Template:Convert
 | See this information on copying this template and modifying it for use on another wiki. |
 | This template uses Lua: |
Template {{convert}} calculates from one measurement unit to another one, and then presents the results formatted. For example:
{{convert|2|km|mi}}→ 2 kilometres (1.2 mi) (km entered, so converted into mile){{convert|7|mi|km}}→ 7 miles (11 km) (mi entered, so converted into km)
Numbers can be rounded, units can be abbreviated into symbols:
{{convert|2|km|mi|2|abbr=on}}→ 2 km (1.24 mi){{convert|7|mi|km|2|abbr=on}}→ 7 mi (11.27 km)
Value ranges can be entered using |to|... or |-|...:
{{convert|2|to|5|km|mi}}→ 2 to 5 kilometres (1.2 to 3.1 mi){{convert|2|-|5|km|mi}}→ 2–5 kilometres (1.2–3.1 mi)
Combined effect example:
{{convert|2|-|5|km|mi|2|abbr=on}}→ 2–5 km (1.24–3.11 mi){{convert|2|and|5|km|mi|sigfig=3|abbr=off}}→ 2 and 5 kilometres (1.24 and 3.11 miles)
Units to convert
Enter units to convert:
{{convert|1|lb|kg}}→ 1 pound (0.45 kg)
- SI units generally accept prefixes, like "m" for micro (10−3), and "M" for mega (106)
- For "per" units, use "/" (slash): kg/ha
- For three-unit units etc.: see Category:Convert-like templates
Unit name or symbol (abbreviation): 1 pound or 1 lb?
By default, the first quantity shows unit name, the second shows the symbol (or abbreviation):
{{convert|1|lb|kg}}→ 1 pound (0.45 kg)
Using |abbr=in is the reverse behaviour to the default:
{{convert|1|lb|kg|abbr=in}}→ 1 lb (0.45 kilograms)
To abbreviate both or neither:
{{convert|1|lb|kg|abbr=on}}→ 1 lb (0.45 kg){{convert|1|lb|kg|abbr=off}}→ 1 pound (0.45 kilograms)
When using scientific notation, the default is for the second (converted) quantity to be displayed using scientific notation:
{{convert|100|e6mi|e6km}}→ 100 million miles (160×106 km)
To display thousands, millions, etc., while abbreviating both input and output units use |abbr=unit:
{{convert|100|e6mi|e6km|abbr=unit}}→ 100 million mi (160 million km)
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 10-mile (16 km) distance.
Default behaviour, for comparison:
{{convert|10|mi|km}} to go→ 10 miles (16 km) to go.
Even with |abbr=on, as per MoS no hyphen is produced with unit symbols.
Rounding: 100 ft is 30 m or 30.5 m or 30.48 m?
By definition, 100 ft equals 30.48 m. 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 figures, 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 (40 m) | |
{{convert|123|ft|m}} |
123 feet (37 m) | same output as with 0 (below) |
{{convert|123|ft|m|0}} |
123 feet (37 m) | |
{{convert|123|ft|m|1}} |
123 feet (37.5 m) | |
{{convert|123|ft|m|2}} |
123 feet (37.49 m) | exact value is 37.4904 m |
{{convert|500|ft|m|-1}} |
500 feet (150 m) | |
{{convert|500|ft|m}} |
500 feet (150 m) | same output as with -1 (above) |
{{convert|500|ft|m|0}} |
500 feet (152 m) | |
{{convert|500|ft|m|1}} |
500 feet (152.4 m) | |
{{convert|500|ft|m|2}} |
500 feet (152.40 m) | exact value is 152.4 m |
{{convert|500|ft|cm}} |
500 feet (15,000 cm) | different output as with 0 (below) |
{{convert|500|ft|cm|0}} |
500 feet (15,240 cm) | |
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 1⁄10 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}}→ 1,200 feet (365.8 m){{convert|1200|ft|m|sigfig=3}}→ 1,200 feet (366 m){{convert|1200|ft|m|sigfig=2}}→ 1,200 feet (370 m){{convert|1200|ft|m|sigfig=1}}→ 1,200 feet (400 m)
Default behaviour, for comparison:
{{convert|1200|ft|m}}→ 1,200 feet (370 m)
Setting |sigfig= to a value less than 1 is meaningless:
{{convert|1200|ft|m|sigfig=0}}→ 1,200 feet (370 m)*
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 (33 ft){{convert|10|m|ft|round=5}}→ 10 metres (35 ft)
Similar: using |round=25 rounds the outcome to a multiple of 25.
{{convert|10|m|ft}}→ 10 metres (33 ft){{convert|10|m|ft|round=25}}→ 10 metres (25 ft)
Default behaviour, for comparison:
{{convert|10|m|ft|sigfig=4}}→ 10 metres (32.81 ft)
In a range, one can round each value individually to the default. Use |round=each:
{{convert|10 x 200 x 3000|m|ft}}→ 10 by 200 by 3,000 metres (33 ft × 656 ft × 9,843 ft){{convert|10 x 200 x 3000|m|ft|round=each}}→ 10 by 200 by 3,000 metres (33 ft × 660 ft × 9,800 ft)
Round to a multiple of a given fraction: 2+3⁄16 inch
Specify the desired denominator using |frac=<some positive integer>. (Denominator is the below-the-slash number, for example the 3 in 1⁄3).
{{convert|5.56|cm|in|frac=16}}→ 5.56 centimetres (2+3⁄16 in){{convert|8|cm|in|frac=4}}→ 8 centimetres (3+1⁄4 in)
The fraction is reduced when possible:
{{convert|8|cm|in|frac=100}}→ 8 centimetres (3+3⁄20 in)
Default behaviour uses decimal notation:
{{convert|5.56|cm|in}}→ 5.56 centimetres (2.19 in)
Rounding temperatures: °C, °F and K
In temperatures, 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.
{{convert|10,000|C|F K}}→ 10,000 °C (18,000 °F; 10,300 K){{convert|10,000.1|C|F K}}→ 10,000.1 °C (18,032.2 °F; 10,273.2 K){{convert|-272|C|F K}}→ −272 °C (−457.60 °F; 1.15 K){{convert|-272|C}}→ −272 °C (−457.60 °F){{convert|-300|C|F K}}→ −300 °C (−508.0 °F; −26.9 K){{convert|0|C|F K}}→ 0 °C (32 °F; 273 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 0.1 degrees Celsius change is a 0.18 degrees Fahrenheit change, 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}}→ 10,000 °C (18,032 °F)
or you set the precision positionally, relative to the decimal point (zero being at the decimal point):
{{convert|10000|C|0}}→ 10,000 °C (18,032 °F)
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 tales place after conversion, so the output is based on the full-precision input. This is useful when the input is produced by {{#expr:}} 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-1 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:
{{convert|4.14159|mi|km|adj=ri0}}→ 4 miles (6.66524 km){{convert|4.14159|mi|km|0|adj=ri0}}→ 4 miles (7 km)
In this case, if the input were rounded before conversion, a different result would be obtained:
{{convert|{{#expr:4.14159 round 0}}|mi|km|0}}→ 4 miles (6 km)
Into multiple units: 10 °C (50 °F; 283 K)
Separate the multiple output units by a space:
{{convert|10|C|F K}}→ 10 °C (50 °F; 283 K){{convert|5|km|mi nmi}}→ 5 kilometres (3.1 mi; 2.7 nmi)
If the output unit names contain spaces, use + as the separator.

- For multiple-unit options like 1 ft 5 in, see § In input and § In output.
Ranges of values
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:
| Separator | Convert | Result | Notes |

Multiple dimensions: 6 m × 12 m (20 ft × 39 ft)
Use by:
{{convert|6|by|12|ft|m}}→ 6 by 12 feet (1.8 by 3.7 m)
Use ×, multiplication sign, or x, letter:
{{convert|6|x|12|m|ft}}→ 6 by 12 metres (20 ft × 39 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}}→ 6 m × 12 m (20 ft × 39 ft)
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}}→ 1 foot 3 inches ([convert: unknown unit])*
Default behaviour, for comparison:
{{convert|1|ft|3|in|mm}}→ 1 foot 3 inches (380 mm)
Words
Spelling of unit name: 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 metres)
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 metres)
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)
Inserted before units: 4 planted acres
{{convert|4|acre||adj=pre|planted}}→ 4 planted acres (1.6 ha)
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 }}→ 4 planted acres (1.6 planted ha){{convert|4|acre||disp=preunit|planted |reforested-}}→ 4 planted acres (1.6 reforested-ha)
After adjective unit: A 10-foot-long corridor
{{convert|10|ft|m|adj=mid|-long}}→ 10-foot-long (3.0 m)
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}}→ 1 metre (3 ft 3 in){{convert|2|metre}}→ 2 metres (6 ft 7 in){{convert|2|metre|abbr=on}}→ 2 m (6 ft 7 in)
- Exception
Entering the unit spelled |foot| forces singular output "foot", whatever the number is.
{{convert|100|foot|abbr=off}}→ 100 foot (30 metres)
Fractions: one-eighth of an imperial pint
The convert template also supports spelling out fractions.
{{convert|3+1/2|oz|g|spell=in}}→ three and a half ounces (99 g)
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}}→ one-eighth of an imperial pint (71 mL)
Wrapping and line breaking
Numbers
Using an SI prefix: gigameter (Gm), or micrometer (μm)
| Metric prefixes | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Units can have an SI prefix like G before the unit: Gm, and giga before the name: gigameter. These are plain multiplication factors.
To illustrate, these are trivial calculations (from meter to meter), showing the multiplication factor:
- 12 Gm (1.2×1010 m)
- 12 μm (1.2×10−5 m)
The prefix can be added before the SI unit (here: unit m for meter):
{{convert|12|Gm|mi|abbr=on}}→ 12 Gm (7,500,000 mi)Mm: 12 Mm (7,500 mi)km: 12 km (39,000 ft)mm: 12 mm (0.47 in)μm: 12 μm (0.012 mm)um: 12 μm (0.012 mm) (letter "u" can be used for "μ" here)
The prefix can be used in the output unit:
{{convert|12000|mi|Mm|abbr=on}}→ 12,000 mi (19 Mm){{convert|12|in|μm|abbr=on}}→ 12 in (300,000 μm)
As an exception, the non-SI unit "inch" can have the "μ" prefix too)
{{convert|12|μm|μin|abbr=on}}→ 12 μm (470 μin)
Engineering notation: 7 × 106 m
In the unit: e6m
Engineering number notations like 7E6 (for 7 × 106) can be entered as a "prefix" to the unit:
{{convert|7|e6m}}→ 7 million metres (23,000,000 ft)
The same is possible for the output unit:
{{convert|23,000,000|ft|e6m}}→ 23,000,000 feet (7.0×106 m)
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}}→ 12.3×10−15 atm (1.23×10−14 atm){{convert|0.00000005|atm|atm|abbr=on}}→ 0.00000005 atm (5.0×10−8 atm)
Input with fractions: 1+1⁄2 inches (38.1 mm)
The number to convert can be written in fractions. Both / (keyboard slash) and ⁄ (fraction slash) are accepted:
{{convert|1/2|in|mm|1}}→ 1⁄2 inch (12.7 mm){{convert|1⁄2|in|mm|1}}→ 1⁄2 inch (12.7 mm)
With integers, use a + sign
{{convert|2+1⁄2|in|mm|1}}→ 2+1⁄2 inches (63.5 mm)
When negative, use a hyphen - and repeat it:
{{convert|-2-1⁄2|in|mm|1}}→ −2+1⁄2 inches (−63.5 mm){{convert|2-1⁄2|in|mm|1}}→ 2–1⁄2 inch (50.8–12.7 mm) Note: this is read as a range{{convert|-2+1⁄2|in|mm|1}}→ [convert: invalid number] Should be a number, not an expression (do not require a calculation)
Output with horizontal fraction bar in: 1/2 inch
Using a double slash (//) returns a horizontal bar fraction:
{{convert|1//2|in|mm|1}}→ 1/2 inch (12.7 mm){{convert|2+1//2|in|mm|1}}→ 2+1/2 inches (63.5 mm)
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}}→ 1,234,567 metres (4,050,417 ft){{convert|1,234,567|m|ft}}→ 1,234,567 metres (4,050,417 ft){{convert|1 234 567|m|ft}}→ [convert: invalid number]
Set |comma=off to remove the separator from the output:
{{convert|1234567|m|ft|comma=off}}→ 1234567 metres (4050417 ft)
Use |comma=gaps to use digit grouping by gap (thin space) as a thousands separator:
{{convert|1234567|m|ft|comma=gaps}}→ 1234567 metres (4050417 ft)
Default behaviour, for comparison:
{{convert|1234567|m|ft}}→ 1,234,567 metres (4,050,417 ft)
Setting |comma=5 will only add the separator when the number of digits is 5 or more:
{{convert|1234|m|ft|comma=5}}→ 1234 metres (4049 ft){{convert|1234567|m|ft|comma=5}}→ 1,234,567 metres (4,050,417 ft)
Default behaviour, for comparison:
{{convert|1234|m|ft}}→ 1,234 metres (4,049 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, x|…:
{{convert|10|m|ft|disp=sqbr}}→ 10 metres [33 ft]{{convert|10|m|ft|disp=comma}}→ 10 metres, 33 ft{{convert|10|m|ft|disp=or}}→ 10 metres or 33 feet
Default behaviour, for comparison:
{{convert|10|m|ft}}→ 10 metres (33 ft)
Setting |disp=br will force a new line (<br/>)
{{convert|10|m|ft|disp=br}}→ 10 metres
33 feet
Also |disp=br() will force a new line, and keep the brackets (useful in tables):
{{convert|10|m|ft|disp=br()}}→ 10 metres
(33 feet)
Setting |disp=x|… allows any text as separator:
{{convert|10|m|ft|disp=x|_MyText_}}→ 10 metres_MyText_33 ft (To display spaces, use )
Flipping (reordering) the two measurements: 1,609.3 metres (1 mile)
Setting |order=flip will flip (swap) the two measurements:
{{convert|1|mi|m|order=flip}}→ 1,609.3 metres (1 mile)
Default behaviour, for comparison:
{{convert|1|mi|m}}→ 1 mile (1,609.3 metres)
When converting to multiple units, the effect is:
{{convert|10|km|mi nmi|order=flip}}→ 6.2137 miles; 5.3996 nautical miles (10 kilometres){{convert|10|km|nmi mi|order=flip}}→ 5.3996 nautical miles; 6.2137 miles (10 kilometres)

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()
|
|---|---|
| 100 kilometres 62 miles |
100 kilometres (62 miles) |
Table columns showing numbers only
Using {convert} in a table cell, with |disp=table splits the result over two columns:
{{convert|10|m|ft|disp=table}}→style="text-align:right;"|10
|style="text-align:right;"|33
|disp=tablecen does the same, and also centers the text:
{{convert|20|m|ft|disp=tablecen}}→style="text-align:center;"|20
|style="text-align:center;"|66
The units are added as a column header:
m ft |disp=table10 33 |disp=tablecen20 66 |disp=<other>(default)30 metres (98 ft)
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 style="display:none">7001100000000000000</span>10 metres (33 ft)
Use both |disp=table and |sortable=on together to produce table columns (pipe symbols) for each value in sortable columns:
m ft A 15+3⁄4 52 B 15.5 51 C 16.0 52.5 D 16 52
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
The table below lists units supported by template {{convert}}. The list is not complete—more complete lists are linked for each dimension. A complete list is at the full list of units.
- Explanation – unit codes
The {{convert}} template uses unit-codes, which are similar to (but not necessarily exactly the same as) the usual written abbreviation for a given unit. These 'unit-codes' are given in column 3 of the following tables, and are accepted as input by the {{convert}} template as the second and third unnamed parameters. For example, {{convert|100|kg|lb}} produces "100 kilograms (220 lb)" and {{convert|100|lb|kg}} produces "100 pounds (45 kg)"
Some units have alternative unit-codes; these are shown in brackets in column 3, e.g. °F (F): either may be entered for Fahrenheit (but not lower-case f).
The unit-codes should be treated as case-sensitive, especially in cases like {{convert|100|Mm|mm}}, which produces "100 megametres (1.0×1011 mm)".
The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the | separator). Typical combination output units are listed below in column 7. For example, {{convert|55|nmi|km mi}} produces "55 nautical miles (102 km; 63 mi)", and {{convert|1|oz|ozt g gr}} produces "1 ounce (0.91 ozt; 28 g; 440 gr)".

'per' units: kg/hl
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}}→ 1,000 kilograms per hectolitre (100 lb/imp gal)
Units of difference: 10 °C higher; how much in °F
When a number is the measurement for a difference, one conversion is done. This may occur in temperatures (°C, °F, K). Compare this to a range, when two conversions are done.
The only available units of difference are: |C-change=, |F-change= and |K-change=.
{{convert|10|C}}→ 10 °C (50 °F), regular temperature{{convert|10|C-change}}→ 10 °C (18 °F), difference (e.g., "The temperature changed from 30 into 40 °C"){{convert|10-15|C}}→ 10–15 °C (50–59 °F), range (e.g., "The temperature is between 10 and 15 °C")
Consistently, into multiple units:
A rise of {{convert|10|C-change|F-change K-change}}→ A rise of 10 °C (18 °F; 10 K)
Multiple units: 1 ft 5 in
In input
Base document § Input multiples 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}}→ 1 yard 2 feet 3 inches (1.60 m){{convert|2|ft|3|in|cm}}→ 2 feet 3 inches (69 cm){{convert|1|lb|5|oz|g}}→ 1 pound 5 ounces (600 g)
In output
Available multiple-unit output options predefined, like ftin and ydftin. The full list is at § Output multiples.
{{convert|2|m|ftin}}→ 2 metres (6 ft 7 in){{convert|2|m|ft in}}→ 2 metres (6.6 ft; 79 in), using a space, returns the decimal point
Default behaviour, for comparison:
{{convert|2|m}}→ 2 metres (6 ft 7 in)
See also:
Currency per unit: $/mi → $/km
Using currency symbols in a $ per unit value, you can convert the per-unit:
{{convert|10|$/mi|$/km}}→ $10 per mile ($6.2/km)
You can set the currency in both values using |$=€:
{{convert|10|$/mi|$/km|$=€}}→ €10 per mile (€6.2/km)
It is not possible to convert the currency. So, this result (mixed currencies) is not possible: $15 per mile (€8.6/km)
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 7/8and 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 Lua error in Module:Wikibase at line 40: attempt to index field 'wikibase' (a nil value). (P2073):
Note: this example uses |qid=Q1056131 (testing for Lua error in Module:Wd at line 196: attempt to index field 'wikibase' (a nil value). (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.
