Template:Convert

Template documentation[view] [edit] [history] [purge]

See Help:Convert for up-to-date and more complete information

Template {{convert}} calculates measurements from one unit (you entered) to another one, and then presents the results. For example:

{{convert|1|km|mi}} → 1 kilometre (0.62 mi)

{{convert|7|mi|km}} → 7 miles (11 km)

That's all.

Usage

Basic examples

Input	Displays as
{{convert|3.21|kg|lb}}	3.21 kilograms (7.1 lb)
{{convert|3.21|kg|lb|0}}	3.21 kilograms (7 lb)
{{convert|10|kg|lb|disp=or}}	10 kilograms or 22 pounds
{{convert|6|ft|5|in|m}}	6 feet 5 inches (1.96 m)
{{convert|10|mi}}	10 miles (16 km)
{{convert|100|mpgus}}	100 miles per US gallon (2.4 L/100 km; 120 mpg-imp)
{{convert|120|km/h}}	120 kilometres per hour (75 mph)
{{convert|18|°C|°F}}	18 °C (64 °F)
{{convert|-15|C|F}}	−15 °C (5 °F)
{{convert|9|e6USgal|abbr=off}}	9 million US gallons (34 megalitres) The "e6" scales the input to millions; the "abbr=off" yields the "mega" in the output. Scaling is only available for Single value conversions. Not all units are supported.
{{convert|1250|sqft|m2|lk=in|sigfig=2}}	1,250 square feet (120 m2) Note 'lk=in' links only the input unit. This example is for illustration only, common units of measurement should not be linked. See: wp:overlink.
{{convert|20.5|m3|cuyd|lk=out|abbr=on}}	20.5 m3 (26.8 cu yd) Note 'lk=out' links only the output unit, cu yd.
{{convert|641|acre|ha sqmi|lk=on}}	641 acres (259 ha; 1.002 sq mi) Note 'lk=on' links all units. Per guidelines, common units should not be linked. See: wp:overlink.
{{convert|641|acre|ha sqmi|2|lk=on}}	641 acres (259.40 ha; 1.00 sq mi) Although 640 acres equals 1 square mile; 641 acres rounded to two decimal places equals 1.00 sq mi.

Options

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

|abbr=on will produce the unit's symbol:

{{convert|1|lb|kg}} → 1 pound (0.45 kg)

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

Adjective: a 10-mile distance

Use |adj=on to produce the adjective form. The difference:

{{convert|10|mi|km}} to go → 10 miles (16 km) to go. -- Regular

A {{convert|10|mi|km|adj=on}} distance → A 10-mile (16 km) distance. -- Adjective

Rounding: 123 ft is 40 m or 37 m or 37.5 m?

Convert supports four types of rounding:

Rounding to a given precision

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 power of ¹⁄₁₀ 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.

Rounding to a given number of significant figures

Specify the desired number of significant figures using |sigfig={some integer greater than zero} as noted above.

Default rounding

If neither the desired precision nor the desired number of significant figures is specified, the conversion 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 figures, whichever is more precise. An exception to this is temperature, wherein the conversion will be rounded either to 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.

Examples of default rounding
Input	Displays as	Note
{{convert|123|ft|m|-1}}	123 feet (40 m)
{{convert|123|ft|m|0}}	123 feet (37 m)
{{convert|123|ft|m|1}}	123 feet (37.5 m)
{{convert|550|ft|m|0}}	550 feet (168 m)	Approximate value is 167.64 m
{{convert|550|ft|m}}	550 feet (170 m)	Rounds to 170, when approximate value is 167.64 m
{{convert|500|ft|m|0}}	500 feet (152 m)	Approximate value is 152.4 m
{{convert|500|ft|m}}	500 feet (150 m)	Rounds to 150, when approximate value is 152.4 m

Range of values: 6 to 17 kg (13 to 37 lb)

Range indicators are entered as the second parameter (between the values). Range separators can be:

to, - (ndash or hyphen), or, and, to(-), +/-:

{{convert|6|to|17|kg|lb|abbr=on}} → 6 to 17 kg (13 to 37 lb)

{{convert|-10|to|-20|C}} → −10 to −20 °C (14 to −4 °F)

{{convert|6|and|17|kg|lb}} → 6 and 17 kilograms (13 and 37 lb)

{{convert|6|to(-)|17|kg|lb}} → 6 to 17 kilograms (13–37 lb)

{{convert|60|+/-|10|m|ft}} → 60 ± 10 metres (197 ± 33 ft)

Multiple dimensions: 6 by 12 feet (1.8 by 3.7 m)

{{convert|6|by|12|ft|m}} → 6 by 12 feet (1.8 by 3.7 m)

{{convert|6|x|12|m|ft}} → 6 by 12 metres (20 ft × 39 ft)

Brackets and separators: 2.4 m, 7.9 ft

Brackets and separators are set by |disp=:

{{convert|2.4|m|ft}} → 2.4 metres (7.9 ft) -- default

{{convert|2.4|m|ft|disp=sqbr}} → 2.4 metres [7.9 ft]

{{convert|2.4|m|ft|disp=comma}} → 2.4 metres, 7.9 ft

{{convert|2.4|m|ft|disp=slash}} → 2.4 m/7.9 ft

{{convert|2.4|m|ft|disp=br}} → 2.4 metres
7.9 feet

Spelling of units: UK metre or US meter?

Default spelling of units is en-UK. To show en-US spelling, use |sp=us:

{{convert|1|m|ft}} → 1 metre (3.3 ft) -- default

{{convert|1|m|ft|sp=us}} → 1 meter (3.3 ft)

Spell out numbers: ten miles

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

{{convert|10|mi|m|spell=in}} → ten miles (16,000 m)

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

{{convert|10|mi|m|spell=on}} → ten miles (sixteen thousand m)

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

{{convert|10|mi|m|spell=In}} → Ten miles (16,000 m)

{{convert|10|mi|m|spell=On}} → Ten miles (sixteen thousand m)

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}} → ten miles (sixteen thousand meters)

Extra words: 4 planted acres

Incomplete secion:

{{convert|4|acre||adj=pre|planted}} → 4 planted acres (1.6 ha)

Table options

For the wikitable structure, there are two options: split over columns and make the table sortable.

Result split over columns in a table

Using {convert} in a table cell, with |disp=table splits the result over two columns:

{{convert|10|m|ft|disp=table}} → align="right"|10

|align="right"|33

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

{{convert|20|m|ft|disp=tablecen}} → align="center"|20

|align="center"|66

The units are added as a column header:

	m	ft
|disp=table	10	33
|disp=tablecen	20	66
|disp=<other> (default)	30 metres (98 ft)

Sorting

Use both |disp=table |sortable=on to make a table column sortable. Only the first column will sort correct.

{{convert|10|m|ft|disp=table|sortable=on}} → (don't let this frighten you)

align="right"|700110000000000000010 |align="right"|33

m	ft
700110000000000000010	33
700120000000000000020	66
700130000000000000030	98

Units overview

See also: complete Convert/list of units

The table below lists units supported by this template. It is divided up according to the quantity being measured. Not all supported units are listed here; there are links to more complete lists for each quantity, and the full list of units shows all units.

The codes listed in the code column (column 3) are accepted as input by the template. These can be used as the second or third unnamed parameter. For some units there exist alternative codes. These are listed in brackets and have been incorporated to make the code more flexible for editors, e.g. °F or F may be entered.

The codes listed in the combinations column (column 7) can be used to produce multiple conversions. They can only be used as the third unnamed parameter, e.g. {{convert|55|nmi|km mi}} produces "55 nautical miles (102 km; 63 mi)".

• {{convert|10|mi|km|spell=In}} → Ten miles (16 km)
• {{convert|1/3|mi|km|adj=on|spell=in}} → one-third-mile (0.54 km)

Options not supported

Free text in a range: 12 m but not greater than 14 m

The range-indicator options like – are limited to a list (see above). It might be needed to use <any text> in a conversion situation, to get a result like:

12 but not greater than 14 metres (39 but not greater than 46 ft)

{{convert}} does not have this option. One can use variant templates:

{{convert/2|12|but not greater than|14|m}} →

12 but not greater than 14 metres (39 but not greater than 46 ft)

For these situations, see the documentation of:

• {{convert/2}}
• {{convert/3}}
• {{convert/4}}
