Quick start

édit

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.

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|xx|120|xx|210|mm|in}} → 100 × 120 × 210 millimetres (3.9 × 4.7 × 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|*|120|*|210|mm|in|abbr=on}} → 100×120×210 mm (3.9×4.7×8.3 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

édit

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 10N).
  • |sigfig=N (where N is a positive number) to specify the number of significant digits (round output to N significant figures).
  • |disp=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|disp=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

édit
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)

Fractions

édit

An input value can be specified as a fraction.

  • {{convert|1/2|in|mm|1}}12 inch (12.7 mm)
  • {{convert|1/2|in|mm|1|adj=on}}12-inch (12.7 mm)
  • {{convert|2+1/2|in|mm|1}}2 12 inches (63.5 mm)
  • {{convert|-2-1/4|in|mm|1}}−2 14 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 12 in)
  • {{convert|219|mm|in|abbr=on|frac=4}} → 219 mm (8 12 in)
  • {{convert|219|mm|in|abbr=on|frac=8}} → 219 mm (8 58 in)
  • {{convert|222|mm|in|abbr=on|frac=8}} → 222 mm (8 34 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 (12 m)
  • {{convert|18.45|in|ft in hand cm|frac=2}} → 18.45 inches (1 12 ft; 18 12 in; 4.2 12 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 12 hands; 46.9 cm)

{{convert|3|x|6|ft}} 3 by 6 feet (0.91 m × 1.83 m) uses " ×&nbsp;" (starts with a space)
{{convert|3|xx|6|ft}} 3 × 6 feet (0.91 × 1.83 m) uses "&nbsp;×&nbsp;"
{{convert|3|*|6|ft}} 3×6 feet (0.91×1.83 m) uses "×"
{{convert|3|+|6|ft}} 3 + 6 feet (0.91 + 1.83 m)
{{convert|3|,|6|ft}} 3, 6 feet (0.91, 1.83 m) uses ",&nbsp;"

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

Extra words

édit

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
{{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

édit

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

édit

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

édit

Convert uses the regular space (" ") and non-breaking space (&nbsp; 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&nbsp;ft, or 3_ft, will not break after "3"

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

A line break (Citakan:Purple) 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 (&nbsp;):

  • When a unit is abbreviated (symbol is shown), the separator is &nbsp;.
{{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 &nbsp; 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 &nbsp;.
{{convert|3|acre|m2|adj=j}} → 3 acres (12,000_m2)*
  • Except, &nbsp; 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, &nbsp; is used as the separator between the value and the name. For example, a measurement spelled as "12 million metres" has &nbsp; 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 cases before "/" and before "[" :
{{convert|12|in|cm|disp=slash}} → 12 inches (30_cm)* (&nbsp; before "/")
{{convert|12|in|cm|disp=sqbr|abbr=on}} → 12_in_[30_cm] (&nbsp; 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 &nbsp; 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 , and xx always use &nbsp;:
{{convert|12|+/-|2|in|cm}} → 12_±_2 inches (30.5_±_5.1_cm)
{{convert|12|,|20|in|cm}} → 12,_20 inches (30,_51_cm)
{{convert|12|xx|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 &nbsp; 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 &nbsp; 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

|disp=unit2
|disp=unit Display input symbol/name (not output; not input value)
|disp=x Join input/output using user-specified text
|comma=5 Only use comma grouping if 5 or more digits
|comma=gaps Use gaps, not comma, to separate groups of digits
|comma=gaps5 Use gaps, but only if 5 or more digits
|adj=nocomma No comma in input or output numbers
|abbr=comma
|frac=N Show imperial number in fractions, denominator=N
|lk=in Link LHS unit name or symbol

|round=5 Rounds calculation to the nearest multiple of 5
|near=5
|disp=5
|round=25 Rounds calculation to the nearest multiple of 25
|round=each In a range, each value is rounded by the default rounding
|sigfig=N Round output value to N significant figures (N is a positive integer)
|sortable=in Output numeric hidden sort field for use in a sortable table (based on input)
|sortable=on
|sortable=out Output numeric hidden sort field for use in a sortable table (based on output)
|debug=yes Sortable: show the normally hidden sort key
|sp=us Use U.S. spelling (like "meter" instead of default "metre")
|spell=in Spell input value in words
|spell=In Spell input value in words with first letter uppercase
|spell=on Spell input and output values in words
|spell=On Spell input and output values in words with first letter uppercase

Examples of number grouping:

  • {{convert|1234|m|ft}} → 1,234 metres (4,049 ft)
  • {{convert|1234|m|ft|comma=5}} → 1234 metres (4049 ft)
  • {{convert|12345|m|ft|comma=5}} → 12,345 metres (40,502 ft)
  • {{convert|1234|m|ft|comma=gaps}}1234 metres (4049 ft)
  • {{convert|1234|m|ft|comma=gaps5}} → 1,234 metres (4,049 ft)*
  • {{convert|123,456,789|m|ft|comma=gaps5}} → 123,456,789 metres (405,041,959 ft)*

Examples of spelling input values:

  • {{convert|10|mi|km|spell=in}} → ten miles (16 km)
  • {{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)

Differences from templates previously used

édit

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 disp=flip, should work with all units.
  • Scaled units like e6USgal are not predefined. With some exceptions, all 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||adj=mid|-long}} (it is also possible to use {{convert|4|ft|0|adj=mid|-long}}, but that 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}}.

Limitations

édit

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:

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)
