Template {{convert}} calculates a measurement value (number × unit) into the same measurement by a different unit, and then presents the results, formatted. See also the unit symbols recognized by this template.

For example:

{{convert|2|km|mi}} → 2 kilometres () (km entered, converted into miles)

{{convert|7|mi|km}} → 7 miles () (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} → Link titleTemplate:Convert/Dual/LoffAoffDbSoff

{{convert|2|-|5|km|mi}} → Template:Convert/Dual/LoffAoffDbSoff

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} → 25 km (Template:Convert/Dual/prnd)

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} → Template:Convert/and

See Help:Convert for more detailed, technical information

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} → 1 pound ()

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha (see § 'per' units: kg/ha and § Currency per unit: $/km)

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

Keng default, ing mumunang dagul papakit ne ing lagyu ning unit, ing kadwa papakit ne ing symbol (o abbreviation):

• {{convert|1|lb|kg}} → 1 pound ()

Using |abbr=in shows the symbol for first (left-hand side) unit, and the name instead of the symbol for the second unit:

• {{convert|1|lb|kg|abbr=in}} → Template:Convert/LoffAinDbSoff

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} → 1 pound ()

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behavior. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A 10-mile () distance.

Default behavior, for comparison:

• {{convert|10|mi|km}} to go → 10 miles () to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals Template:Convert/LoffAoffDoutSoff. In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}	123 feet ()
{{convert|123|ft|m}}	123 feet ()	same output as with 0 (below)
{{convert|123|ft|m|0}}	123 feet ()
{{convert|123|ft|m|1}}	123 feet ()
{{convert|123|ft|m|2}}	123 feet ()	123 feet is exactly 37.4904 m which is rounded to 37 m if this parameter is not specified at all
{{convert|500|ft|m|-1}}	500 feet ()
{{convert|500|ft|m}}	500 feet ()	same output as with -1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}	500 feet ()
{{convert|500|ft|m|1}}	500 feet ()
{{convert|500|ft|m|2}}	500 feet ()	exact value is 152.4 m
{{convert|500|ft|cm|-3}}	500 feet ()
{{convert|500|ft|cm}}	500 feet ()	same output as with -3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}	500 feet ()

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with an integer as the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this integer. For instance, if the result is 8621 and the rounding parameter is "−2", 8600 will be displayed. If the result is "123.456" and the parameter is "0", 123 will be displayed. Essentially a positive or zero rounding parameter specifies the number of decimal places; a negative value specifies the number of trailing zeroes.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} → 1,200 feet ()
• {{convert|1200|ft|m|sigfig=3}} → 1,200 feet ()
• {{convert|1200|ft|m|sigfig=2}} → 1,200 feet ()
• {{convert|1200|ft|m|sigfig=1}} → 1,200 feet ()

Default behavior, for comparison:

• {{convert|1200|ft|m}} → 1,200 feet ()

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → 1,200 feet () N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} → 10 metres ()
• {{convert|10|m|ft|round=5}} → 10 metres ()

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} → 10 metres ()
• {{convert|10|m|ft|round=25}} → 10 metres ()

Default behavior, for comparison:

• {{convert|10|m|ft|sigfig=4}} → 10 metres ()

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} → 10 x 200 x 3,000 metres ()
• {{convert|10 x 200 x 3000|m|ft|round=each}} → 10 x 200 x 3,000 metres ()

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} → 5.56 centimetres (

For currency conversion into US dollars, see Template:To USD

Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.

For example:

{{convert|2|km|mi}} → (km entered, converted into miles)

{{convert|7|mi|km}} → (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} →

{{convert|2|-|5|km|mi}} →

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} →

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} → Template:Convert/C
2. {{convert|10,000.1|C|F K}} → Template:Convert/C
3. {{convert|-272|C|F K}} → Template:Convert/C
4. {{convert|-272|C}} → Template:Convert/C
5. {{convert|100|C|F K}} → Template:Convert/C
6. {{convert|0|C|F K}} → Template:Convert/C

The precision of the input number in example (1) is one digit, but the precision of its kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a Template:Convert/LoffAoffDxSoffT, and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} → Template:Convert/C

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that it is not possible to round above the decimal place (|adj=ri-1N is invalid). Neither is there support for significant figures, multiples of a number, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → Template:Convert/LoffAoffDbSri0 N (precisions are mismatched)
• Template:Tlc → Template:Convert/LoffAoffDbSri0 Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → 4 miles () N (rounds intermediate calculation, giving a different result)

Into multiple units: Template:Convert/C

Separate the multiple output units by a space:

• {{convert|10|C|F K}} → Template:Convert/C
• {{convert|5|km|mi nmi}} → 5 kilometres (Template:Convert/mi nmi)

If the output unit names contain spaces, use + as the separator.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions: Template:Convert/x

Use by:

• {{convert|6|by|12|ft|m}} → Template:Convert/by

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} → Template:Convert/x

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} → Template:Convert/x

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} → Template:Convert/,

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → Template:Convert/LoffAoffDbSoff2 N

Default behavior, for comparison:

• {{convert|1|ft|3|in|mm}} → Template:Convert/LoffAoffDbSoff2

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} → Template:Convert/x

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → 1 metre ()—default

{{convert|1|m|ft|sp=us}} → 1 meter ()

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} → 10 miles ()

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} → 10 miles ()

To make the first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} → 10 miles ()
• {{convert|10|mi|m|spell=On}} → 10 miles ()

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} → Template:Convert/LoffAoffDbSpreNa

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} → Template:Convert/LoffAoffDpreunitSoffNa
• {{convert|4|acre||disp=preunit|planted |reforested-}} → Template:Convert/LoffAoffDpreunitSoffNa

After adjective unit: A Template:Convert/LoffAoffDoutSmid corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} → Template:Convert/LoffAoffDbSmid

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} → Template:Convert/metre
• {{convert|2|metre}} → Template:Convert/metre
• {{convert|2|metre|abbr=on}} → Template:Convert/metre

Exception

Entering the unit "foot" instead of "ft" forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} → Template:Convert/foot

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} → Template:Convert/oz

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} → Template:Convert/imppt

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} → Template:Convert/e6mi
• {{convert|120|e6acre}} → Template:Convert/e6acre
• {{convert|120|e6acre|e3km2}} → Template:Convert/e6acre

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} → Template:Convert/e6mi

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} → Template:Convert/e6mi
• {{convert|100|e6mi|e6km|abbr=off}} → Template:Convert/e6mi

Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

• Template:Convert/Gm
• Template:Convert/μm

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} → Template:Convert/Gm
• Mm: Template:Convert/Mm
• km:
• mm: Template:Convert/mm
• μm: Template:Convert/μm
• um: Template:Convert/um (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.

For example:

{{convert|2|km|mi}} → (km entered, converted into miles)

{{convert|7|mi|km}} → (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} →

{{convert|2|-|5|km|mi}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} → 23,000,000 feet (Template:Convert/e6m)

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),

• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 0.000000000000. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.

For example:

{{convert|2|km|mi}} → (km entered, converted into miles)

{{convert|7|mi|km}} → (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.

For example:

{{convert|2|km|mi}} → (km entered, converted into miles)

{{convert|7|mi|km}} → (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding

{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

Example for (P2386): Note: this example uses |qid=Q1513315 (testing for (Q1513315))

• (Q613628): {{convert|input=P2386|qual=Q613628|ft|abbr=on}} →
• (Q1395645): {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} →

For currency conversion into US dollars, see Template:To USD

Template {{convert}} calculates from one measurement unit to another one, and then presents the results, formatted. The complete list of unit symbols recognized by the template is here.

For example:

{{convert|2|km|mi}} → (km entered, converted into miles)

{{convert|7|mi|km}} → (mi entered, converted into km)

Numbers can be rounded, units can be abbreviated into symbols:

{{convert|2|km|mi|2|abbr=on}} →

{{convert|7|mi|km|2|abbr=on}} →

Value ranges can be entered using |to|... or |-|...:

{{convert|2|to|5|km|mi}} →

{{convert|2|-|5|km|mi}} →

Combined effect example:

{{convert|2|-|5|km|mi|2|abbr=on}} →

{{convert|2|and|5|km|mi|sigfig=3|abbr=off}} →

See Help:Convert for more detailed, technical information

Units to convert

See also: the summary at Complete list of units for {{Convert}} and the complete list at Module:Convert/documentation/conversion data

Enter units to convert from into:

• {{convert|1|lb|kg}} →

SI units generally accept prefixes, like "m" for milli (10⁻³), and "M" for mega (10⁶)

For "per" units, use "/" (slash): kg/ha

For three-unit units, etc., see Template:Cl

Unit name or symbol (abbreviation): 1 pound or 1 lb?

By default, the first quantity shows the unit name, the second shows the symbol (or abbreviation):

• {{convert|1|lb|kg}} →

Using |abbr=in is the reverse behaviour to the default:

• {{convert|1|lb|kg|abbr=in}} →

To abbreviate both or neither:

• {{convert|1|lb|kg|abbr=on}} →
• {{convert|1|lb|kg|abbr=off}} →

Convenience: {{cvt}} has |abbr=on by default

Template {{cvt}} is the same as {{convert}}, except that it has |abbr=on as the default behaviour. In {{cvt}}, all other options are available. So:

{{cvt|1|lb|kg}} → 1 lb (0.45 kg)

is equivalent to:

{{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)

Adjective: a 10-mile distance

Use |adj=on to produce the adjectival (hyphenated) form:

• A {{convert|10|mi|km|adj=on}} distance → A distance.

Default behaviour, for comparison:

• {{convert|10|mi|km}} to go → to go.

|adj=on does not produce hyphens with unit symbols, as per :

• A {{convert|9|in|cm|adj=on|abbr=on}} nail → A nail.

Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?

See Template:Section link for a more mathematical description of the rounding options

By definition, 100 ft equals . In practical use, it is common to round the calculated metric number. With that, there are several possibilities.

Default rounding

By {{Convert}} default, the conversion result will be rounded either to precision comparable to that of the input value (the number of digits after the decimal point—or the negative of the number of non-significant zeroes before the point—is increased by one if the conversion is a multiplication by a number between 0.02 and 0.2, remains the same if the factor is between 0.2 and 2, is decreased by 1 if it is between 2 and 20, and so on) or to two significant digits, whichever is more precise. An exception to this is rounding temperatures (see below).

Examples of rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}
{{convert|123|ft|m}}		same output as with 0 (below)
{{convert|123|ft|m|0}}
{{convert|123|ft|m|1}}
{{convert|123|ft|m|2}}		The more-exact value is 37.4904 m or so, which gets converted to 37 m if this parameter is not specified at all.
{{convert|500|ft|m|-1}}
{{convert|500|ft|m}}		same output as with −1 (above), because the conversion factor is between 0.2 and 2 (hence, it should produce same double-zero precision (−2) as in the input value), but the conversion must produce two significant digits at a minimum (hence, a higher single-zero precision (−1) is used)
{{convert|500|ft|m|0}}
{{convert|500|ft|m|1}}
{{convert|500|ft|m|2}}		exact value is 152.4 m
{{convert|500|ft|cm|-3}}
{{convert|500|ft|cm}}		same output as with −3 (above), because the conversion factor is between 20 and 200 (hence, it should decrease input value's double-zero precision (−2) by 2), but the conversion must produce two significant digits at a minimum (hence, a higher triple-zero precision (−3) is used)
{{convert|500|ft|cm|0}}

Convert supports four types of rounding:

Round to a given precision: use a precision number

Specify the desired precision with the fourth unnamed parameter (or third unnamed parameter if the "convert to" parameter is omitted; or fifth unnamed parameter if a range is specified; or fourth unnamed parameter again if a range is specified and the "convert to" parameter is omitted; needs to be replaced with a "precision" named parameter). The conversion is rounded off to the nearest multiple of to the power of this number. For instance, if the result is 8621 and the round number is "-2", the result will be 8600. If the result is "234.0283043" and the round number is "0", the result will be 234.

Round to a given number of significant figures: |sigfig=

To specify the output number to be with n significant figures use |sigfig=<number>:

• {{convert|1200|ft|m|sigfig=4}} →
• {{convert|1200|ft|m|sigfig=3}} →
• {{convert|1200|ft|m|sigfig=2}} →
• {{convert|1200|ft|m|sigfig=1}} →

Default behaviour, for comparison:

• {{convert|1200|ft|m}} →

Setting |sigfig= to a value less than 1 is meaningless:

• {{convert|1200|ft|m|sigfig=0}} → N

Round to a multiple of 5: 15, 20, 25, ...

Using |round=5 rounds the outcome to a multiple of 5.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=5}} →

Similar: using |round=25 rounds the outcome to a multiple of 25.

• {{convert|10|m|ft}} →
• {{convert|10|m|ft|round=25}} →

Default behaviour, for comparison:

• {{convert|10|m|ft|sigfig=4}} →

In a range, one can round each value individually to the default. Use |round=each:

• {{convert|10 x 200 x 3000|m|ft}} →
• {{convert|10 x 200 x 3000|m|ft|round=each}} →

Round to a multiple of a given fraction: inch

Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in ).

• {{convert|5.56|cm|in|frac=16}} →
• {{convert|8|cm|in|frac=4}} →

The fraction is reduced when possible:

• {{convert|8|cm|in|frac=100}} →

Default behaviour uses decimal notation:

• {{convert|5.56|cm|in}} →

Rounding temperatures: °C, °F and K

In temperatures, the conversion will be rounded either to the precision comparable to that of the input value or to that which would give three significant figures when expressed in kelvins, whichever is more precise.

1. {{convert|10,000|C|F K}} →
2. {{convert|10,000.1|C|F K}} →
3. {{convert|-272|C|F K}} →
4. {{convert|-272|C}} →
5. {{convert|100|C|F K}} →
6. {{convert|0|C|F K}} →

The precision of the input number in example (1) is one digit, but the precision of its Kelvins expression is three, so the precision of the Fahrenheit conversion is made three (made 180...) . (1) and (2) seem to belie the fact that a , and make the 32 degrees difference shown in (1) begin to seem off somehow. Result (1) seems off until you set the significant figures yourself with |sigfig=:

{{convert|10000|C|sigfig=5}} →

or you set the precision positionally, relative to the decimal point (zero being at the decimal point):

{{convert|10000|C|0}} →

The precision of the input number in example (2) is six, so the precision of the Fahrenheit output is, whereas before, Kelvins had determined it to be three. Examples (3) and (4) show how this can be hidden and generate questions, but it occurs there because the Kelvins conversion generated two fractional parts. (Before it was the input number that generated the fractional part.) In example (3) the three input digits converted into five significant output digits because of the two digits after the decimal point, generated by the Kelvins conversion. This happened again in (5), but in (6) decimal fractions were neither given as input nor induced by the Kelvins conversion.

Rounding input

There is limited support for rounding the displayed input number. The rounding takes place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by Template:Tlc or otherwise available to a higher precision than is usefully displayed, and it's desirable to avoid double-rounding.

To round the input to a specified number of digits after the decimal point, use one of the parameters:

• |adj=ri0
• |adj=ri1
• |adj=ri2
• |adj=ri3

Note that there is no |adj=ri-1N or similar for rounding above the decimal place. Neither is there support for significant figures, multiples of 5, or any other output-rounding feature.

The default precision is computed based on the input, so an explicit output precision must usually be supplied:

• Template:Tlc → N (precisions are mismatched)
• Template:Tlc → Y

In this case, if the input were rounded before conversion, a different result would be obtained:

• Template:Tlc → N (double rounding)

Into multiple units:

Separate the multiple output units by a space:

• {{convert|10|C|F K}} →
• {{convert|5|km|mi nmi}} →

If the output unit names contain spaces, use + as the separator.

See also:

• For multiple-unit options like 1 ft 5 in, see Template:Section link and Template:Section link.

Ranges of values

Para a conversion of a difference, lon me ing #Units of difference.

A range converts two values and separates them by your choice of words and punctuation.

A range: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:
Template:Convert/doc/range separator list

Multiple dimensions:

Use by:

• {{convert|6|by|12|ft|m}} →

Use ×, multiplication sign, or x, letter:

• {{convert|6|x|12|m|ft}} →

In science, the formal way is to set |x| and |abbr=on (keeping dimensions right, like in area = x km²):

• {{convert|6|x|12|m|ft|abbr=on}} →

Lists of values: 20, 40, or 60 miles

{{convert|20|,|40|, or|60|mi}} →

About feet, inch in ranges and multiples

While it is possible to enter feet, inch in a simple conversion, this is not possible for ranges:

• {{convert|1|ft|3|in|x|3|ft|5|in|mm}} → N

Default behaviour, for comparison:

• {{convert|1|ft|3|in|mm}} →

However, converting metric units into feet and inches with |order=flip can produce the desired output:

• {{convert|380|x|1040|mm|ftin|order=flip}} →

Words

Spelling of unit name: international metre or US meter?

Default spelling of units is in the en (generic) locale. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → —default

{{convert|1|m|ft|sp=us}} →

Spell out numbers: ten miles

To write a number in words, use |spell=in:

• {{convert|10|mi|m|spell=in}} →

To spell out both in and out values, use |spell=on:

• {{convert|10|mi|m|spell=on}} →

To make first letter a capital, use |spell=In, |spell=On

• {{convert|10|mi|m|spell=In}} →
• {{convert|10|mi|m|spell=On}} →

Remember that the spelling of the units (ft, m) is independently set by |abbr=. To the extreme:

• {{convert|10|mi|m|spell=on|abbr=off|sp=us}} →

Inserted before units: 4 planted acres

• {{convert|4|acre||adj=pre|planted}} →

disp=preunit is similar, but has no separator after the specified text, and can have different text for the output value:

• {{convert|4|acre||disp=preunit|planted }} →
• {{convert|4|acre||disp=preunit|planted |reforested-}} →

After adjective unit: A corridor

Note that two units (in this case, ft and m) are required. Use with just one unit will generate an error message.

{{convert|10|ft|m|adj=mid|-long}} →

Plurals: 1 inch, 2 inches

The unit symbol is singular always. Depending on the preceding number only, a unit name can be shown plural.

• {{convert|1|metre}} →
• {{convert|2|metre}} →
• {{convert|2|metre|abbr=on}} →

Exception

Entering the unit spelled |foot| forces singular output "foot", whatever the number is.

• {{convert|100|foot|abbr=off}} →

Fractions: one-eighth of an imperial pint

The convert template also supports spelling out fractions.

• {{convert|3+1/2|oz|g|spell=in}} →

Any additional words needed for the fraction can also be added at the end of the template.

• {{convert|1/8|imppt|ml|spell=in|adj=pre|of an}} →

Wrapping and line breaking

See Template:Section link

Spelling out "thousands", "millions", etc.

Most unit codes accept a prefix of e3 (thousand) or e6 (million) or e9 (billion).

• {{convert|100|e6mi|e6km}} →
• {{convert|120|e6acre}} →
• {{convert|120|e6acre|e3km2}} →

To display both input and output in scientific notation, use |abbr=on

• {{convert|100|e6mi|e6km|abbr=on}} →

To spell out "thousands", "millions", etc., |abbr=unit abbreviates the unit; |abbr=off displays both full unit names.

• {{convert|100|e6mi|e6km|abbr=unit}} →
• {{convert|100|e6mi|e6km|abbr=off}} →

Numbers

Using an SI prefix: gigametre (Gm), or micrometre (μm)

Template:Sidebar metric prefixes (small) Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigametre. These are plain multiplication factors.

To illustrate, these are trivial calculations (from metre to metre), showing the multiplication factor:

The prefix can be added before the SI unit (here: unit m for metre):

• {{convert|12|Gm|mi|abbr=on}} →
• Mm:
• km:
• mm:
• μm:
• um: (letter "u" can be used for "μ" here)

The prefix can be used in the output unit:

• {{convert|12000|mi|Mm|abbr=on}} →
• {{convert|12|in|μm|abbr=on}} →

As an exception, the non-SI unit "inch" can have the "μ" prefix too:

• {{convert|12|μm|μin|abbr=on}} →

Further information: Help:Convert units § SI prefixes

Engineering notation: 7 × 10⁶ m

In the unit: e6m

Engineering notation can be entered as a "prefix" to the unit:

• {{convert|70|e6m}} →

The same is possible for the output unit:

• {{convert|23,000,000|ft|e6m}} →

Any standard unit (not a combination, multiple, or built-in unit) can have such a prefix:

• e3 (thousand),
• e6 (million),
• e9 (billion),
• e12 (trillion),
• e15 (quadrillion).

Scientific notation: 1.23 × 10⁻¹⁴

In scientific notation, a number is written like 1.23×10⁻¹⁴. The plain number has exactly one digit before the decimal point.

With {{convert}}, the input can be in e-notation such as 12.3e4. This value is displayed as a power of ten, and the output is displayed in scientific notation, except that an output value satisfying 0.01 <= v < 1000 is shown as a normal number. In addition, if the output value is 1000 and sigfig=4 is used, the value is displayed as a normal number.

• {{convert|12.3e-15|atm|atm|abbr=on}} →
• {{convert|0.00000005|atm|atm|abbr=on}} →

Input with fractions:

The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:

• {{convert|1/2|in|mm|1}} →
• {{convert|1⁄2|in|mm|1}} →

With positive mixed numbers (a positive integer and a fraction), use a + sign

• {{convert|2+1⁄2|in|mm|1}} →

With negative mixed numbers, use a hyphen - and repeat it:

• {{convert|-2-1⁄2|in|mm|1}} →

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → . This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → N This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.

Horizontal fraction bar: 1/2 inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} →
• {{convert|6+3//8|in|mm|1}} →

Using a negative value for |frac= provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} →
• {{convert|161.9|mm|frac=-8}} →

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} →
• {{convert|1,234,567|m|ft}} →

Set |comma=off to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} →

Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} →

Default behaviour, for comparison:

• {{convert|1234567|m|ft}} →

Setting |comma=5 will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} →
• {{convert|1234567|m|ft|comma=5}} →

Default behaviour, for comparison:

• {{convert|1234|m|ft}} →

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by |disp=.
Options are: b (the default), sqbr, comma, or, br, br(), x|…:

• {{convert|10|m|ft|disp=sqbr}} →
• {{convert|10|m|ft|disp=comma}} →
• {{convert|10|m|ft|disp=or}} →

Default behaviour, for comparison:

• {{convert|10|m|ft}} →

Setting |disp=br will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} →

Also |disp=br() will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} →

Setting |disp=x|… allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → (To display spaces, use  )

Flipping (reordering) the two measurements:

Setting |order=flip will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} →

Default behaviour, for comparison:

• {{convert|1|mi|m}} →

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} →
• {{convert|10|km|nmi mi|order=flip}} →

Fixed ordering of output units:

Setting |order=out shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} →
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} →

See also: § Displaying parts of the output.

Displaying parts of the result:

It is possible to display only parts of the conversion result:

Convert	Output	Returns
{{convert|2|cuyd|m3}}		Regular output (for comparison)
{{convert|2|cuyd|m3|abbr=values}}		Input and output numbers
{{convert|2|cuyd|m3|disp=unit}}		Input unit
{{convert|2|cuyd|m3|disp=unit|adj=on}}		Input unit, adjective (hyphenated)
{{convert|2|cuyd|cuyd|disp=out}}		Input (workaround. Note repetition of unit in input)
{{convert|2|cuyd|m3|abbr=~}}		Input: both name and symbol
{{convert|2|cuyd|m3|disp=unit2}}		Output unit (symbol)
{{convert|2|cuyd|m3|disp=unit2|abbr=off}}		Output unit (name)
{{convert|2|cuyd|m3|disp=number}}		Output value
{{convert|2|cuyd|m3|disp=out}}		Output value and unit name
{{convert|2|cuyd|m3|disp=out|abbr=off}}		Output value and unit symbol

Display both input name and symbol: 2 kilopascals [kPa]

Setting |abbr=~ returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} →
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → A pressure

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

|disp=br adds a line-break and omits brackets.

|disp=br() adds a line-break and does add brackets to the converted value. This may be useful in tables:

|disp=br	|disp=br()

Table columns

Using {convert} in a table cell, with |disp=table splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the |abbr= parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

|disp=tablecen does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

The units are added as a column header:

	kilograms	pounds	stone and pounds
|disp=table
|disp=table and |abbr=on
|disp=table and |abbr=off
|disp=tablecen
|disp=<other> (default)

Sorting

Use |sortable=on to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} → <span data-sort-value="7001100000000000000♠"></span>10 metres (33 ft)

showing: .

Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	15.75 m
B	15.5 m
C	16 m
D	16 m

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

See also: Convert/list of units

Units are case-sensitive: use Template:Xt, not Template:!xt or Template:!xt

'per' units: kg/hl, miles per gallon

When using a slash (/), a unit like kg/hl is recognized as kilograms per hectolitre and will be converted with other mass/volume units.

• {{convert|1000|kg/hl}} →

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} →

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} →

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• {{convert|10|C}} → (standard temperature conversion)
• {{convert|10–15|C}} → (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (|C, |F and |K), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": |C-change, |F-change and |K-change.

Compare the following two examples with the two above:

• {{convert|10|C-change}} → increase in temperature
• {{convert|10–15|C-change}} → warmer than normal

To produce multiple units in the output:

• {{convert|10|C-change|F-change K-change}} → difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} →
• {{convert|2|ft|3|in|cm}} →
• {{convert|1|lb|5|oz|g}} →

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} →
• {{convert|2|m|ft in}} → , using a space, returns the decimal point

Default behaviour, for comparison:

• {{convert|2|m}} →

See also:

• {{hands}} a length used to measure horses
• {{Long ton}} a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|10|$/mi|$/km}} →
• {{convert|1500|$/ozt|$/g}} →

You can set the currency in both values using |$=€:

• {{convert|10|$/mi|$/km|$=€}} →

It is not possible to convert the currency. So, this result (mixed currencies) is not possible: Template:!mxt N

Using convert inside templates

For usage in template code, like infoboxes, {{Convert}} has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into {{Convert}}-accepted input.

Your template can accept |input=16 7/8 and use {{#invoke:Convert/helper|number|16 7/8}} → 16+7/8

Using a Wikidata property

• Adding the Wikidata property code, like code |input=P2073, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use |qid=.

Example for (P2073): Note: this example uses |qid=Q1056131 (testing for (Q1056131))

• {{convert|input=P2073|qid=Q1056131|ftin|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} →
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} →

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the |qual= parameter to specify which of the values you want to use.

This template prefers inline formatting of parameters.

Parameter		Description	Type	Status
Value	1	The value to convert.	Number	required
From unit	2	The unit for the provided value. Alimbawa km	String	required
To units	3	The units to convert into. Separate units by a space for multiple outputs. In an output unit, use + for a multiplication space. Alimbawa mi nmi	String	suggested

Note that the following cases are not interpreted as mixed numbers:

• {{convert|2-1⁄2|in|mm|1}} → Template:Convert. This is interpreted as a range from 2 inches to 1⁄2 inch.
• {{convert|-2+1⁄2|in|mm|1}} → Template:Convert Template:Nay This is neither a mixed number nor a range, and mathematical expressions requiring calculations are not allowed here.
• {{convert|2+½|in|mm|1}} → Template:Convert Template:Nay Fractions consisting of a single Unicode character are not allowed either.

Horizontal fraction bar: Template:Sfrac inch

Using a double slash (//) provides a horizontal fraction bar for the original (input) unit:

• {{convert|1//2|in|mm|1}} → Template:Convert
• {{convert|6+3//8|in|mm|1}} → Template:Convert

Using a negative value for Template:Para provides a horizontal fraction bar for the converted (output) unit:

• {{convert|12.7|mm|frac=-2}} → Template:Convert
• {{convert|161.9|mm|frac=-8}} → Template:Convert

Thousands separator: 1,000 mi or 1000 mi

In input, a comma for thousands separator is accepted but not required; a gap (space) is not accepted. In output, by default, the thousand separator is the comma:

• {{convert|1234567|m|ft}} → Template:Convert
• {{convert|1,234,567|m|ft}} → Template:Convert

Set Template:Para to remove the separator from the output:

• {{convert|1234567|m|ft|comma=off}} → Template:Convert

Use Template:Para to use digit grouping by gap (thin space) as a thousands separator:

• {{convert|1234567|m|ft|comma=gaps}} → Template:Convert

Default behavior, for comparison:

• {{convert|1234567|m|ft}} → Template:Convert

Setting Template:Para will only add the separator when the number of digits is 5 or more:

• {{convert|1234|m|ft|comma=5}} → Template:Convert
• {{convert|1234567|m|ft|comma=5}} → Template:Convert

Default behavior, for comparison:

• {{convert|1234|m|ft}} → Template:Convert

Output manipulation

Brackets and separators: 10 m [33 ft]

Punctuation that distinguishes the two measurements is set by Template:Para.
Options are: b (the default), sqbr, comma, semicolon, or, br, br(), x!…:

• {{convert|10|m|ft|disp=sqbr}} → Template:Convert
• {{convert|10|m|ft|disp=comma}} → Template:Convert
• {{convert|10|m|ft|disp=semicolon}} → Template:Convert
• {{convert|10|m|ft|disp=or}} → Template:Convert

Default behavior, for comparison:

• {{convert|10|m|ft}} → Template:Convert

Setting Template:Para will force a new line (<br/>)

• {{convert|10|m|ft|disp=br}} → Template:Convert

Also Template:Para will force a new line, and keep the brackets (useful in tables):

• {{convert|10|m|ft|disp=br()}} → Template:Convert

Setting Template:Para allows any text as separator:

• {{convert|10|m|ft|disp=x|_MyText_}} → Template:Convert (To display spaces, use  )

Flipping (reordering) the two measurements: Template:Convert

Setting Template:Para will flip (swap) the two measurements:

• {{convert|1|mi|m|order=flip}} → Template:Convert

Default behavior, for comparison:

• {{convert|1|mi|m}} → Template:Convert

When converting to multiple units, the effect is:

• {{convert|10|km|mi nmi|order=flip}} → Template:Convert
• {{convert|10|km|nmi mi|order=flip}} → Template:Convert

Fixed ordering of output units: Template:Convert

Setting Template:Para shows the output-units as ordered; the input unit is skipped:

• {{convert|100|C|F C K|abbr=on|order=out}} → Template:Convert
• {{convert|200|PS|kW hp|0|abbr=on|order=out}} → Template:Convert

See also: § Displaying parts of the output.

Displaying parts of the result: Template:Convert

It is possible to display only parts of the conversion result: The following examples show how to display only a part of the result.

Note: in Convert, abbr is synonym for unit symbol

Convert	Returns	Components
{{convert|2|cuyd|m3}}	Template:Convert	all (default conversion)
{{convert|2|cuyd|m3|abbr=on}}	Template:Convert	all (default conversion, abbr)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	numbers only
{{convert|2|cuydTemplate:Bg}}	Template:Convert	input value (workaround)
{{convert|2|cuydTemplate:Bg}}	Template:Convert	input value abbr (workaround)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	input unit
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	input unit, adjectival (hyphenated)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	input unit, adjectival (abbr so not hyphenated)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	input unit abbr
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output value, symbols
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output value, names
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output, adjective
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output number
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output unit (abbr by default)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output unit (name)
{{convert|2|cuyd|m3Template:Bg}}	Template:Convert	output unit (abbr)

Display both input name and symbol: 2 kilopascals [kPa]

Setting Template:Para returns both name and symbol of the first (input) unit:

• {{convert|2|kPa|psi|abbr=~}} → Template:Convert
• A {{convert|2|kPa|psi|abbr=~|adj=on}} pressure → Template:Nowrap

Table options

For the wikitable structure, there are three options: add a line-break, split the result over columns and make the table sortable.

Enforced line break

Template:Para adds a line-break and omits brackets.

Template:Para adds a line-break and does add brackets to the converted value. This may be useful in tables:

Template:Para	Template:Para
Template:Convert	Template:Convert

Table columns

Using {convert} in a table cell, with Template:Para splits the result over two (or more) columns. By default units are not included in the table, however, they can be added using the Template:Para parameter. Multiple-unit outputs, like ftin, always output their units to the table.

{{convert|10|m|ft|disp=table}} →

Template:Convert

Template:Para does the same, and also centers the text:

{{convert|20|m|ft|disp=tablecen}} →

Template:Convert

Deng units miragdagan la bilang column header:

	kilograms	pounds	stone and pounds
Template:Para	Template:Convert
Template:Para and Template:Para	Template:Convert
Template:Para and Template:Para	Template:Convert
Template:Para	Template:Convert
Template:Para (default)	Template:Convert

Sorting

Use Template:Para to include a hidden numerical sortkey in the output, suitable for use in a table with sortable columns. Technically, this places a hidden string before the actual displayed values:

{{convert|10|m|ft|sortable=on}} Template:Nowrap

showing: Template:Convert.

Use both Template:Para and Template:Para together to produce table columns (pipe symbols) for each value in sortable columns:

	m	m	ft
A	Template:Val	Template:Convert
B	Template:Val	Template:Convert
C	Template:Val	Template:Convert
D	Template:Val	Template:Convert

The generated sortkey is calculated in a consistent way based on both the value and its unit as passed to the convert template. In most cases convert uses the passed value converted to SI base units. It is therefore not necessarily the displayed value or other alternate units and is calculated regardless of output format options. Using different units or different order of units in individual rows should therefore not lead to incorrect sorting, although variations in rounding can give surprising results, since an unrounded number is used for the sortkey.

Units

The conversion factors and physical constants are sourced here.

All units

Template:Selfref Template:Hatnote Template:Convert/list of units

'per' units: kg/ha, miles per gallon

When using a slash (/), a unit like kg/ha is recognized as kilograms per hectare and will be converted in to other mass/area units. A unit in the numerator is not required.

• {{convert|1000|kg/ha}} → Template:Convert
• {{convert|350|/in2}} → Template:Convert

Population density (inhabitants per square mile) can be converted using

• {{convert|10|PD/sqmi|PD/km2}} → Template:Convert

Vehicular fuel efficiency, commonly expressed in miles per gallon or litres per 100 km can also be converted

• {{convert|26|mpgUS|l/100km mpgimp}} → Template:Convert

Units of difference: Expressing a change or difference in temperature

We have already discussed standard temperature conversions (°C, °F, K), as shown in these two examples:

• #invoke:DemoTemplate (standard temperature conversion)
• #invoke:DemoTemplate (standard temperature range conversion)

When expressing a temperature change (e.g., "The temperature increased by 10 °C"), or when comparing temperatures (e.g., "10 to 15 °C warmer"), we cannot use the standard temperature units (Template:Para, Template:Para and Template:Para), which refer to points on the respective scale. Instead, we must use one of the following "units of difference": Template:Para, Template:Para and Template:Para.

Compare the following two examples with the two above:

• #invoke:DemoTemplate increase in temperature
• #invoke:DemoTemplate warmer than normal

To produce multiple units in the output:

• #invoke:DemoTemplate difference

Multiple units: 1 ft 5 in

In input

Base document Template:Section link lists options for multiple unit input (like ft,in). It can catch predefined sets only (units that can be subdivided; e.g., yd into ft):

• {{convert|1|yd|2|ft|3|in}} → Template:Convert
• {{convert|2|ft|3|in|cm}} → Template:Convert
• {{convert|1|lb|5|oz|g}} → Template:Convert

In output

Available multiple-unit output options predefined, like ftin and ydftin. The full list is at Template:Section link.

• {{convert|2|m|ftin}} → Template:Convert
• {{convert|2|m|ft in}} → Template:Convert, using a space, returns the decimal point

Default behavior, for comparison:

• {{convert|2|m}} → Template:Convert

See also:

• Template:Tl a length used to measure horses
• Template:Tl a weight in ton, cwt, qr and lb

Currency per unit: $/mi → $/km

Using currency symbols in a $ per unit value, you can convert the per-unit:

• {{convert|3.39|$/USgal|$/L}} → Template:Convert
• {{convert|10000|€/ha|€/acre}} → Template:Convert
• {{convert|10|¢/mi|¢/km}} → Template:Convert
• {{convert|1500|¥/lb|¥/kg}} → Template:Convert

You can also set the currency in both values using Template:Para:

• {{convert|10|$/mi|$/km|$=€}} → Template:Convert

It is not possible to convert the currency:

• {{convert|10|$/lb|€/kg}} → Template:Convert Template:Nay

So, this result (mixed currencies) is not possible: Template:!mxt Template:Nay

Using convert inside templates

For usage in template code, like infoboxes, Template:Tlf has these options:

Pre-formatting fraction input

• Module:Convert/helper can read regular input and pre-format it into Template:Tlf-accepted input.

Your template can accept Template:Para and use {{#invoke:Convert/helper|number|16 7/8}} → #invoke:Convert/helper

Using a Wikidata property

• Adding the Wikidata property code, like code Template:Para, to your template code automatically returns the Wikidata property for that article, and convert it. Both number and unit are read.

Note: to return that property value for an other article, use Template:Para.

Example for Template:Wikidata property link of Template:Wikidata entity link:

• {{convert|input=P2073|qid={{get QID|Cessna 208 Caravan}}|ftin|abbr=on}} → Template:Convert
• {{convert|input=P2073|qid=Q1056131|km|abbr=on}} → Template:Convert
• {{convert|input=P2073|qid=Q1056131|km|abbr=on|disp=out}} → Template:Convert

For example see template:Infobox Telescope.

Sometimes a property may have more than one value against it in Wikidata. You can use the Template:Para parameter to specify which of the values you want to use.

Example for Template:Wikidata property link: Note: this example uses Template:Para (testing for Template:Wikidata entity link)

• Template:Wikidata entity link: {{convert|input=P2386|qual=Q613628|ft|abbr=on}} → Template:Convert
• Template:Wikidata entity link: {{convert|input=P2386|qual=Q1395645|ft|abbr=on}} → Template:Convert
