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

{{convert|2|km|mi}} → 2 kilometres (1.2 mi)
{{convert|7|mi|km}} → 7 miles (11 km)

Units to convert

Enter units to convert:

  • {{convert|1|lb|kg}} → 1 pound (0.45 kg)
  • Units are listed below.

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

By default, the first value shows unit name spelled out, the second the symbol (or abbreviation). Use Template:Para to change this behaviour:

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

To abbreviate both:

  • {{convert|1|lb|kg|abbr=on}} → 1 lb (0.45 kg)
  • {{convert|1|lb|kg|abbr=off}} → 1 pound (0.45 kilograms)

Template:Para is the reverse behaviour to the default, Template:Para:

  • {{convert|1|lb|kg|abbr=in}} → 1 lb (0.45 kilograms)

When using scientific notation, the default is for the second (converted) value to display with scientific notation:

  • {{convert|100|e6mi|e6km}} → 100 million miles (160×10^6 km)

To display thousands, millions, etc., while abbreviating both input and output units use Template:Para:

  • {{convert|100|e6mi|e6km|abbr=unit}} → 100 million mi (160 million km)

Convenience: Template:Tlf has Template:Para by default

Template {{cvt}} is similar to Template:Tlf, but has Template:Para as the default behaviour. In Template:Tlf, all other options are available. So:

{{cvt|1|lb|kg}}Template:Cvt

is equal to:

{{convert|1|lb|kg|abbr=on}}Template:Cvt

Adjective: a 10-mile distance

Use Template:Para to produce the adjective 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.

This option does not work with Template:Para.

Template:AnchorRounding: 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 Template:Tlf 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 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 Template:Frac 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: Template:Para

To specify the output number to be with n significant figures use Template:Para:

  • {{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 Template:Para is meaningless

  • {{convert|1200|ft|m|sigfig=0}} → 1,200 feet (370 m)*

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

Using Template:Para 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 Template:Para 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 Template:Para:

  • {{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: Template:Frac inch

Specify the desired denominator using Template:Para. (Denominator is the below-the-slash number, for example the 3 in Template:Frac).

  • {{convert|5.56|cm|in|frac=16}} → 5.56 centimetres (2 316 in)
  • {{convert|8|cm|in|frac=4}} → 8 centimetres (3 14 in)

The fraction is reduced when possible:

  • {{convert|8|cm|in|frac=100}} → 8 centimetres (3 320 in)

Default behaviour, for comparison:

  • {{convert|8|cm|in}} → 8 centimetres (3.150 in)

Template:AnchorRounding 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.

  1. Script error: No such module "DemoTemplate".
  2. Script error: No such module "DemoTemplate".
  3. Script error: No such module "DemoTemplate".
  4. Script error: No such module "DemoTemplate".
  5. Script error: No such module "DemoTemplate".
  6. Script error: No such module "DemoTemplate".

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 Template:Para:

Script error: No such module "DemoTemplate".

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

Script error: No such module "DemoTemplate".

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.

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.

Ranges of values

Template:Hatnote 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:

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 Template:Para (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 Template:Para:

{{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 Template:Para:

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

To spell out both in and out values, use Template:Para:

  • {{convert|10|mi|m|spell=on}}Lua error in Module:Convert at line 403: attempt to call upvalue 'speller' (a string value).

To make first letter a capital, use Template:Para, Template:Para

  • {{convert|10|mi|m|spell=In}} → 10 miles (16,000 m)*
  • {{convert|10|mi|m|spell=On}}Lua error in Module:Convert at line 403: attempt to call upvalue 'speller' (a string value).

Remember that the spelling of the units (ft, m) is independently set by Template:Para. To the extreme:

  • {{convert|10|mi|m|spell=on|abbr=off|sp=us}}Lua error in Module:Convert at line 403: attempt to call upvalue 'speller' (a string value).

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|1/4|oz|g|spell=in}}14 ounce (7.1 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}}18 of an imperial pint (71 mL)*

Numbers

Using an SI prefix: gigameter (Gm), or micrometer (μm)

Template:Sidebar metric prefixes (small) 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)

Template:Further information

Engineering notation: 7 × 106 m

In the unit: e6m

Engineering number notations like 7Template:Smallcaps6 (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 (7.0×10^6 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 Template:Rnd. The plain number has exactly one digit before the decimal point.

With Template:Tlf, 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 12 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}}12 inch (12.7 mm)
  • {{convert|1⁄2|in|mm|1}}12 inch (12.7 mm)

With integers, use a + sign

  • {{convert|2+1⁄2|in|mm|1}}2 12 inches (63.5 mm)

When negative, use a hyphen - and repeat it:

  • {{convert|-2-1⁄2|in|mm|1}}−2 12 inches (−63.5 mm)
  • {{convert|2-1⁄2|in|mm|1}} → 2–12 inch (50.8–12.7 mm) Note: this is read as a range
  • {{convert|-2+1⁄2|in|mm|1}}[convert: invalid number] Template:Nay Should be a number, not an expression (do not require a calculation)

Output with horizontal fraction bar in: Template:Sfrac 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] Template:Nay

Set Template:Para to remove the separator from the output:

  • {{convert|1234567|m|ft|comma=off}} → 1234567 metres (4050417 ft)

Use Template:Para 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 Template:Para or Template:Para 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)
  • {{convert|1234|m|ft|comma=gaps5}} → 1,234 metres (4,049 ft)*
  • {{convert|1234567|m|ft|comma=gaps5}} → 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 Template:Para.
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 Template:Para will force a new line (<br/>)

  • {{convert|10|m|ft|disp=br}} → 10 metres
    33 feet

Also Template:Para will force a new line, and keep the brackets:

  • {{convert|10|m|ft|disp=br()}} → 10 metres
    (33 feet)

Setting Template:Para allows any text as separator:

  • {{convert|10|m|ft|disp=x|_MyText_}} → 10 metres_MyText_33 ft—(To display spaces, use &nbsp;)

Flipping (reordering) the two measurements: 1,609.3 metres (1 mile)

Setting Template:Para 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)

Displaying parts of the result: 2 (1.5)

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

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=~}} → 2 kilopascals [kPa] (0.29 psi)
  • A {{convert|2|kPa|psi|abbr=~|adj=on}} pressureTemplate: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
100 kilometres
62 miles
100 kilometres
(62 miles)

Table columns showing numbers only

Using {convert} in a table cell, with Template:Para splits the result over two columns:

{{convert|10|m|ft|disp=table}}
style="text-align:right;"|10

|style="text-align:right;"|33

Template:Para 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
Template:Para 10 33
Template:Para 20 66
Template:Para (default) 30 metres (98 ft)

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:Nowrap7001100000000000000</span>10 metres (33&nbsp;ft)

Use both Template:Para and Template:Para together to produce table columns (pipe symbols) for each value in sortable columns:

m ft
A 15 34 52
B 15.5 51
C 16.0 52.5

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.

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)

Template:AnchorUnits 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: Template:Para, Template:Para and Template:Para.

  • Script error: No such module "DemoTemplate"., regular temperature
  • Script error: No such module "DemoTemplate"., difference (e.g., "The temperature changed from 30 into 40 °C")
  • Script error: No such module "DemoTemplate"., 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 Template:Slink 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 Template:Slink.

  • {{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)

  • {{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}} → $10 per mile ($6.2/km)

You can set the currency in both values using Template:Para:

  • {{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: Template:!mxt Template:Nay
