Quick start

By default, the name of the input unit is shown, while the output is abbreviated using the unit's symbol. If wanted, names or symbols can be used, and the output precision can be specified.

{{convert|123.4|ft|m}} → 123.4 feet (37.6 m)
{{convert|123.4|ft|m|abbr=on}} → 123.4 ft (37.6 m)
{{convert|123.4|ft|m|abbr=off}} → 123.4 feet (37.6 metres)
{{convert|123.4|ft|m|abbr=off|sp=us}} → 123.4 feet (37.6 meters)
{{convert|123.4|ft|m|0}} → 123.4 feet (38 m)
{{convert|123.4|ft|m|3}} → 123.4 feet (37.612 m)

To avoid overlinking, units are not normally linked, but they can be when needed.

{{convert|12300|m2|rood|abbr=off|lk=on}} → 12,300 square metres (12.2 roods)
{{convert|12300|m2|rood|abbr=off|lk=out}} → 12,300 square metres (12.2 roods)

A convert can be used in an adjectival phrase, and user-specified text can be inserted.

{{convert|1500|ft|m|adj=on}} → 1,500-foot (460 m)
{{convert|1500|ft|m|adj=mid|-long}} → 1,500-foot-long (460 m)

If no output unit is specified, a default is used.

{{convert|123.4|ft}} → 123.4 feet (37.6 m)
{{convert|123.4|ft|abbr=on}} → 123.4 ft (37.6 m)
{{convert|1500|ft||adj=mid|-long}} → 1,500-foot-long (460 m)

The last example used || to explicitly show that the output unit has been omitted. If that is not done, the result is an error, and holding the mouse over the error message shows that "-long" is misinterpreted as the output unit.

{{convert|1500|ft|adj=mid|-long}} → 1,500-foot (^{[convert: unknown unit]})

The input and outputs can be "flipped". When flipped, an option such as |lk=out means "link the right-hand side".

{{convert|12300|m2|rood|abbr=off|lk=out}} → 12,300 square metres (12.2 roods)
{{convert|12300|m2|rood|abbr=off|lk=out|disp=flip}} → 12.2 roods (12,300 square metres)
{{convert|12300|m2|rood|abbr=off|lk=in|disp=flip}} → 12.2 roods (12,300 square metres)

The input value can be spelled.

{{convert|5|mi|km|spell=in|0}} → five miles (8 km)
{{convert|5|mi|km|spell=In|0}} → Five miles (8 km)

Ranges of values are supported.

{{convert|3|-|6|ft}} → 3–6 feet (0.91–1.83 m)
{{convert|3|to|6|ft|abbr=off|sp=us}} → 3 to 6 feet (0.91 to 1.83 meters)

A range can use more than two values.

{{convert|100|x|120|x|210|mm|in}} → 100 by 120 by 210 millimetres (3.9 in × 4.7 in × 8.3 in)
{{convert|100|x|120|x|210|mm|in|abbr=on}} → 100 mm × 120 mm × 210 mm (3.9 in × 4.7 in × 8.3 in)
{{convert|100|by|120|by|210|mm|in}} → 100 by 120 by 210 millimetres (3.9 by 4.7 by 8.3 in)

Some input units consist of multiple components.

{{convert|5|ft|8|in}} → 5 feet 8 inches (1.73 m)
{{convert|11|st|3|lb|kg}} → 11 stone 3 pounds (71 kg)

An output can be a combination of several units.

{{convert|123|nmi|km mi}} → 123 nautical miles (228 km; 142 mi)
{{convert|123|hPa|psi inHg|abbr=on|lk=on}} → 123 hPa (1.78 psi; 3.6 inHg)

Some outputs consist of multiple units.

{{convert|123.4|m|ydftin}} → 123.4 metres (134 yd 2 ft 10 in)
{{convert|123.4|kg|stlb}} → 123.4 kilograms (19 st 6 lb)

Rounding

By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.

If the default is not wanted, the precision of output values can be specified using:

|N (where N is a number) to specify the number of digits to be displayed after the decimal mark (round output to N decimal places).
|-N (where -N is a negative number) to specify the number of digits before the decimal mark that should be replaced with zero (round output to nearest 10^N).
|sigfig=N (where N is a positive number) to specify the number of significant digits (round output to N significant figures).
|round=5 to round the output to the nearest multiple of 5.

Examples:

{{convert|1234|ft|m}} → 1,234 feet (376 m)
{{convert|1234|ft|m|2}} → 1,234 feet (376.12 m)
{{convert|1234|ft|m|-1}} → 1,234 feet (380 m)
{{convert|1234|ft|m|round=5}} → 1,234 feet (375 m)
{{convert|1234|ft|m|sigfig=2}} → 1,234 feet (380 m)
{{convert|1234|ft|m|sigfig=4}} → 1,234 feet (376.1 m)
{{convert|1230|ft|m}} → 1,230 feet (370 m)
{{convert|1230|ft|m|0}} → 1,230 feet (375 m)
{{convert|1230|ft|m|1}} → 1,230 feet (374.9 m)
{{convert|5670|sqft}} → 5,670 square feet (527 m²)
{{convert|5670|sqft|-2}} → 5,670 square feet (500 m²)

Spell

Use US (en-US) spelling for unit names

Use |sp=us to specify that unit names should be displayed with US spelling:

{{convert|6|km}} → 6 kilometres (3.7 mi)
{{convert|6|km|sp=us}} → 6 kilometers (3.7 mi)

Spell out numbers in words

Use |spell=in to specify that the input value should be spelled in words, or |spell=In (uppercase "I") to start with an uppercase letter:

{{convert|5|mi|km|spell=in}} → five miles (8.0 km)
{{convert|5|mi|km|spell=in|abbr=off|0}} → five miles (8 kilometres)
{{convert|5|mi|km|spell=In|0}} → Five miles (8 km)
{{convert|5|mi|km|spell=In|abbr=off|0}} → Five miles (8 kilometres)
{{convert|2+1/4|mi|km|abbr=off|0|spell=In}} → Two and a quarter miles (4 kilometres)
{{convert|2+1/4|mi|km|abbr=off|0|spell=In|sp=us}} → Two and a fourth miles (4 kilometers)

The input and output can be "flipped", as shown in these examples. Logically, the resulting first number is spelled:

{{convert|5|mi||0|disp=flip|spell=in}} → eight kilometres (5 mi)
{{convert|5|mi||0|disp=flip|spell=In|abbr=off}} → Eight kilometres (5 miles)

The "||" provides an empty output unit to mean "use the default".

Both input and output values can be spelled:

{{convert|5|mi|m|-2|spell=on|sp=us|abbr=off}} → five miles (eight thousand meters)
{{convert|5|mi|m|-2|spell=On|sp=us|abbr=off}} → Five miles (eight thousand meters)

Thousands separator

In input, a comma for thousands separator is accepted. In output, by default, the thousands 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)

Set |comma=off to remove any thousands separator in the result:

{{convert|1,234,567|m|ft|comma=off}} → 1,234,567 metres (4,050,417 ft)^*

Use |comma=gaps to set thousands grouping by gap (<space>):

{{convert|1234567|m|ft}} → 1,234,567 metres (4,050,417 ft) (To compare, default)
{{convert|1234567|m|ft|comma=gaps}} → 1234567 metres (4050417 ft)

Setting |comma=5 or |comma=gaps5 will only add the separator only when the number of digits is 5 or more:

{{convert|1234|m|ft}} → 1,234 metres (4,049 ft) (To compare, default)
{{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)^*

In input, gaps are not accepted.

Fractions

An input value can be specified as a fraction.

{{convert|1/2|in|mm|1}} → 1⁄2 inch (12.7 mm)
{{convert|1/2|in|mm|1|adj=on}} → 1⁄2-inch (12.7 mm)
{{convert|2+1/2|in|mm|1}} → 2+1⁄2 inches (63.5 mm)
{{convert|-2-1/4|in|mm|1}} → −2+1⁄4 inches (−57.2 mm)
{{convert|1/2|in|mm|1|spell=in}} → one-half inch (12.7 mm)

If two slashes are used, a horizontal fraction bar is used.

{{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)

An output can be expressed with a fraction using |frac=N where N is the denominator. For example, |frac=8 rounds the output to the nearest eighth.

{{convert|219|mm|in|abbr=on}} → 219 mm (8.6 in)
{{convert|219|mm|in|abbr=on|frac=2}} → 219 mm (8+1⁄2 in)
{{convert|219|mm|in|abbr=on|frac=4}} → 219 mm (8+1⁄2 in)
{{convert|219|mm|in|abbr=on|frac=8}} → 219 mm (8+5⁄8 in)
{{convert|222|mm|in|abbr=on|frac=8}} → 222 mm (8+3⁄4 in)

A fraction is applied to the output unit (if there is only one), or to non-SI units (if using a combination), except that if a precision is also specified, the fraction only applies to the hand unit.

{{convert|18.45|in|m|frac=2}} → 18.45 inches (1⁄2 m)
{{convert|18.45|in|ft in hand cm|frac=2}} → 18.45 inches (1+1⁄2 ft; 18+1⁄2 in; 4.2+1⁄2 hands; 46.9 cm)
{{convert|18.45|in|ft in hand cm|frac=2|1}} → 18.45 inches (1.5 ft; 18.5 in; 4.2+1⁄2 hands; 46.9 cm)

`{{convert\|3\|x\|4\|to\|6+1/2\|x\|8+3/4\|in}}`	3 by 4 to 6+1⁄2 by 8+3⁄4 inches (76 mm × 102 mm to 165 mm × 222 mm)

Ranges can be specified in the first parameter.

Convert	Output

`{{convert\|3x4x24\|in}}`	3 by 4 by 24 inches (76 mm × 102 mm × 610 mm)

Extra words

Some options provide text that is included in the output, as shown in the following examples.

Convert	Output	Description
`{{convert\|4\|ft\|\|adj=mid\|-long}}`	4-foot-long (1.2 m)	Adjectival with mid-text between input and output (sets `\|adj=on`)
`{{convert\|40\|acre\|\|adj=pre\|planted}}`	40 planted acres (16 ha)	Text before the input unit
`{{convert\|4\|m\|\|disp=preunit\|+ }}`	4+ metres (13+ ft)	Same text before the input and output units
`{{convert\|4\|m\|\|disp=preunit\|+ \|or more }}`	4+ metres (13 or more ft)	Different text before the input and output units
`{{convert\|20\|impfloz\|\|disp=x\|, approximately }}`	20 imperial fluid ounces, approximately 570 ml; 19 US fl oz	Text before the output (replaces the join)
`{{convert\|100\|m\|\|disp=x\|/day (\|/day)}}`	100 metres/day (330 ft/day)	Text before and after the output (replaces the join)

In each of the above examples, "||" provides an empty output unit which causes the default output to be used. An output unit, possibly empty, must be specified to avoid the template interpreting the extra text as the output unit. For example, using {{convert|4|ft|adj=mid|-long}} has the same effect as using {{convert|4|ft|-long|adj=mid}}, namely that an error would occur because "-long" would be used as the output unit. The following illustrates the error (hover the mouse over the error text to see that the problem is due to "-long" ) and how it may be avoided.

{{convert|4|ft|adj=mid|-long}} → 4-foot (^{[convert: unknown unit]})
{{convert|4|ft||adj=mid|-long}} → 4-foot-long (1.2 m)
{{convert|4|ft| |adj=mid|-long}} → 4-foot-long (1.2 m)
{{convert|4|ft|m|adj=mid|-long}} → 4-foot-long (1.2 m)

Displaying parts of a conversion

The following examples show how to display only some part of the output result.

Convert	Output	Description
`{{convert\|2\|cuyd\|m3}}`	2 cubic yards (1.5 m³)	normal convert
`{{convert\|2\|cuyd\|m3\|abbr=values}}`	2 (1.5)	input and output values
`{{convert\|2\|cuyd\|m3\|disp=unit}}`	cubic yards	input unit
`{{convert\|2\|cuyd\|m3\|disp=unit\|adj=on}}`	cubic-yard	input unit, adjectival (hyphenated)
`{{convert\|2\|cuyd\|cuyd\|0\|disp=out\|abbr=off}}`	2 cubic yards	input (workaround)
`{{convert\|2\|cuyd\|m3\|disp=unit2}}`	m³	output unit (symbol)
`{{convert\|2\|cuyd\|m3\|disp=unit2\|abbr=off}}`	cubic metres	output unit (name)
`{{convert\|2\|cuyd\|m3\|disp=number}}`	1.5	output value
`{{convert\|2\|cuyd\|m3\|disp=out}}`	1.5 m³	output value and unit
`{{convert\|2\|cuyd\|m3\|abbr=off\|disp=out}}`	1.5 cubic metres	output value and unit

Flipping the order of output

To invert the order of measurements, simply use |order=flip

{{convert|10|km|mi}} → 10 kilometres (6.2 mi) (default)
{{convert|10|km|mi|order=flip}} → 6.2 miles (10 km)

Wrapping and line breaking

Convert uses the regular space (" ") and non-breaking space (  which shows: " ") to control line-breaking (also called wrapping/nowrapping).

Wrapping is possible where a space (" ") is used. Prevent wrapping is enforced by using the non-breaking space, that ties and keeps text elements together.

3 feet may break after "3"

3 ft, or 3_ft, will not break after "3"

In the examples below, an   is shown as "_" (red underscore): "3_ft".

A line break (<br/>) forces a newline (line break), and so overrules any nowrap setting at that point.

Within a measurement (value+unit)

The separator between the value and the unit can be a space or a nonbreaking space ( ):

When a unit is abbreviated (symbol is shown), the separator is  .

{{convert|12|m|ft|abbr=on}} → 12_m (39_ft)

When a unit is not abbreviated (name is shown), the separator is a space.

{{convert|12|m|ft}} → 12 metres (39_ft)

This can be set (overruled) to be   by |adj=j (for 'join').

{{convert|12|m|ft|adj=j}} → 12 metres (39_ft)^*

Some units do not have a symbol and always use a space (such as acre).

{{convert|3|acre|m2|abbr=on}} → 3 acres (12,000_m²)

Except, option |adj=j ("join") forces the separator to be  .

{{convert|3|acre|m2|adj=j}} → 3 acres (12,000_m²)^*

Except,   is always used when a measurement is in multiple units.

{{convert|1|ft|6|in|cm}} → 1_foot 6_inches (46_cm)

{{convert|2|m|ftin}} → 2 metres (6_ft 7_in)

Except, if option |adj=on is used and the unit is not abbreviated, the separator is a hyphen ("-").

{{convert|2|m|ftin|adj=on}} → 2-metre (6_ft 7_in)

When the name of a number is used,   is used as the separator between the value and the name. For example, a measurement spelled as "12 million metres" has   before "million" and a space afterwards.

{{convert|12|e6m}} → 12_million metres (39,000,000_ft)

Between measurements

A space is used as the separator in a join between the first and second measurement.

{{convert|3|ft|m}} → 3 feet (0.91_m)

Except for the special case before "[" :

{{convert|12|in|cm|disp=sqbr|abbr=on}} → 12_in_[30_cm] (  before "[")

Multiple output measurements (by listing units) always use a space between measurements ("; " has a space after ";").

{{convert|2|acre|m2 sqft ha}} → 2 acres (8,100_m²; 87,000_sq_ft; 0.81_ha)

Between components of a measurement (e.g., in a range; between foot–inch)

A measurement in multiple units always uses a space between components ("1 foot 6 inches" has   before the unit names, but a space after "foot").

{{convert|1|ft|6|in|cm}} → 1_foot 6_inches (46_cm)

In a range, spaces are generally used to separate items. For example, "to" and "or" have a space before and after in the following.

{{convert|12|to|20|in|cm}} → 12 to 20 inches (30 to 51_cm)

{{convert|12|or|20|in|cm}} → 12 or 20 inches (30 or 51_cm)

The ranges +/- and , always use  :

{{convert|12|+/-|2|in|cm}} → 12_±_2 inches (30.5_±_5.1_cm)

{{convert|12|,|20|in|cm}} → 12,_20 inches (30,_51_cm)

The "to-" range (same as "to(-)") is an exception. When a unit is not abbreviated, "to" has   before and a space after.

{{convert|12|to-|20|in|cm}} → 12 to-^{[convert: unknown unit]}

The "x" range is an exception. When a unit is abbreviated, "×" has a space before and   after.

{{convert|12|x|20|in|cm}} → 12 by 20 inches (30_cm ×_51_cm)

Overrule by setting a line break

Parameter |disp=br adds a forced line break (<br/>) between measurements; brackets are omitted.

{{convert|12|m|ft|disp=br}} → 12 metres
39 feet

Units in singular or plural

Unit symbols are always singular. Unit names can be singular or plural. A unit is singular when the number is exactly +1:

{{convert|0.5|ft|m|abbr=off}} → 0.5 feet (0.15 metres)
{{convert|1|ft|m|abbr=off}} → 1 foot (0.30 metres)
{{convert|2|ft|m|abbr=off}} → 2 feet (0.61 metres)

Note: as of November 2014, in certain conditions this topic can behave unexpected (bug).

Setting |adj=1 makes these values singular: (−1 <= v and v < 0) or (0 < v and v <= 1)

{{convert|2|ft|m|adj=1|abbr=off}} → 2 feet (0.61 metres)^*
{{convert|1|ft|m|adj=1|abbr=off}} → 1 foot (0.30 metres)^*
{{convert|0.5|ft|m|adj=1|abbr=off}} → 0.5 feet (0.15 metres)^*
{{convert|0|ft|m|adj=1|abbr=off}} → 0 feet (0 metres)^*
{{convert|-0.5|ft|m|adj=1|abbr=off}} → −0.5 feet (−0.15 metres)^*
{{convert|-1|ft|m|adj=1|abbr=off}} → −1 foot (−0.30 metres)^*
{{convert|-2|ft|m|adj=1|abbr=off}} → −2 feet (−0.61 metres)^*

Complicated grammar

This example is from article Fort McHenry:

The American defenders had 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons.

This result is not possible straightforward by using {{convert}}. However, it can be made in three steps. Short: step 1: get the values right using {{convert}}, step 2: make them into hardcoded text, step 3: edit text into correct spelling and grammar. Long:

Step 1: Enter the input numbers and units in {{convert}} just to get the calculated output:

had {{convert|18|,|24|,|32|lb|kg|0}} cannons

→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons

The core conversion should look good now. You can save this (or preview).

Step 2: We need the resulting text in plain code in the page, not as a {{convert|...}} template.

For this, add subst: to the template name

 (for 'substitute') :
had {{subst:convert|18|,|24|,|32|lb|kg|0}} cannons


As a check: the preview result should show the conversion correct, with the values still right. Now save this.
→ had 18, 24, 32 pounds (8, 11, 15 kg) cannons


Step 3: When opening the edit screen again, you'll see that the text is there in code.

You can change the text as needed. The template {{convert|...}} itself has disappeared. The edit screen text is:
had 18,&nbsp;24,&nbsp;32 pounds (8,&nbsp;11,&nbsp;15&nbsp;kg) cannons
You can edit this text to add the grammar:
had 18-,_24-_and_32-pounder (8,&nbsp;11_and_15&nbsp;kg) cannons 
After saving your edit, it shows:
→ "had 18-, 24- and 32-pounder (8, 11 and 15 kg) cannons".

Other options are (all replacing step 2 in the above):

B. Save the primary {{convert}} conversion, and then copy-paste the values from the plain read page into edit-page.
C. Put the {{convert|...}} code in Special:ExpandTemplates, and paste the result from there into the edit screen.

Differences from templates previously used

Before December 2013, {{convert}} was implemented by a series of templates, not a module. Following are some differences between the new and old convert implementations.

Using {{subst:convert|...}} works with the module.
The module checks unit types and displays an error message if a mismatch occurs.
Ranges and all options, including order=flip, work with all units.
Scaled units like e6USgal are not predefined. With some exceptions, all standard (simple) units accept prefixes e3, e6, e9, e12, e15.
The module uses an empty unit code rather than 0 to mean "use the default unit", as in {{convert|4|ft||abbr=on}}

Note that writing {{convert|4|ft|0|abbr=on}} sets the output precision to zero.

The functionality of {{convert/3}} and {{convert/4}} is handled by the module, except that the module does not support arbitrary text to separate items in a range. Furthermore, the predefined separator words such as "by" and "to" behave in exactly the same manner as they do for standard converts, so a conversion like {{convert/3|2|x|4|x|6|m|ft}} would need to use the new * separator rather than x to produce exactly the same output with the module.
The module does not have a problem with template loops, and will allow pointless conversions like {{convert|123|m|m}}.

DeprecatedThis list: view • talk • edit

Deprecated options should not be used. They may produce incorrect or undesired results and there is no guarantee that they will be supported in the future.

abbr=comma is deprecated. Use comma=off instead
abbr=mos, setting range separators, is deprecated (not MOS compliant). Use |by| or |x| instead
adj=1 is deprecated. No need to deviate from MOS regarding plurals
adj=flip is deprecated. Use order=flip instead
adj=j is deprecated. No need to use NBSP before full unit name. See MOS
adj=nocomma is deprecated. Use comma=off instead
disp=2 is deprecated. Use disp=output only instead
disp=5 is deprecated. Use round=5 instead
disp=flip is deprecated. Use order=flip instead
disp=flip5 is deprecated. Use |order=flip |round=5 instead
disp=nocomma is deprecated. Use comma=off instead
disp=slash, disp=s, disp=/ are deprecated. Use disp=or instead
disp=u2 is deprecated. Use disp=unit2 instead
near=5 is deprecated. Use round=5 instead
sing= is deprecated in any situation. Use adj= instead
Range separator |xx| is deprecated (not MOS compliant). Use |x| instead
Range separator |*| is deprecated (not MOS compliant). Use |x| instead
Range separator |&| is deprecated. Use |and| instead
Range separator |to-| is deprecated. Use |to(-)| instead

Limitations

This is a list of features that the module may be expected to support, but which will not work.
Composite units cannot be used in a range:

{{convert|2|ft|6|in|to|3|ft|9|in}} → 2 feet 6 inches (^{[convert: unknown unit]})^*

If an expression is wanted, it has to use {{#expr:...}}:

{{convert|3*12|ft|mm}} → 3×12 feet (910×3,660 mm)
{{convert|{{#expr:3*12}}|ft|mm}} → 36 feet (11,000 mm)
