Template {{convert}} is used to convert a value from one unit of measurement to another. This page provides an overview of the options available when using the template.


Asking questions[ಬದಲಾಯಿಸಿ]

Units[ಬದಲಾಯಿಸಿ]

Quick start[ಬದಲಾಯಿಸಿ]

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[ಬದಲಾಯಿಸಿ]

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[ಬದಲಾಯಿಸಿ]

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)

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 which assume that it is reasonable to round the output to the nearest integer:

  • {{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".

Fractions[ಬದಲಾಯಿಸಿ]

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)

Joins[ಬದಲಾಯಿಸಿ]

The |disp= ("display") option may be used to "join" the input and output, as shown in the following examples.

Convert Output
{{convert|3|-|6|ft}} 3–6 feet (0.91–1.83 m)
{{convert|3|–|6|ft}} 3–6 feet (0.91–1.83 m)
{{convert|3|and|6|ft}} 3 and 6 feet (0.91 and 1.83 m)
{{convert|3|or|6|ft}} 3 or 6 feet (0.91 or 1.83 m)
{{convert|3|to|6|ft}} 3 to 6 feet (0.91 to 1.83 m)
{{convert|3|to(-)|6|ft}} 3 to 6 feet (0.91–1.83 m)
{{convert|3|to about|6|ft}} 3 to about 6 feet (0.91 to about 1.83 m)
{{convert|3|+/-|6|ft}} 3 ± 6 feet (0.91 ± 1.83 m)
{{convert|3|±|6|ft}} 3 ± 6 feet (0.91 ± 1.83 m)
{{convert|3|by|6|ft}} 3 by 6 feet (0.91 by 1.83 m)
{{convert|3|x|6|ft}} 3 by 6 feet (0.91 m × 1.83 m)
{{convert|3|xx|6|ft}} 3 × 6 feet (0.91 × 1.83 m)
{{convert|3|*|6|ft}} 3×6 feet (0.91×1.83 m)
{{convert|3|+|6|ft}} 3 + 6 feet (0.91 + 1.83 m)
{{convert|3|,|6|ft}} 3, 6 feet (0.91, 1.83 m)
{{convert|3|, and|6|ft}} 3, and 6 feet (0.91, and 1.83 m)
{{convert|3|, or|6|ft}} 3, or 6 feet (0.91, or 1.83 m)

The following ranges provide different output when units are abbreviated.

Convert Output
{{convert|3|to(-)|6|ft|abbr=on}} 3 to 6 ft (0.91–1.83 m)
{{convert|3|x|6|ft|abbr=on}} 3 ft × 6 ft (0.91 m × 1.83 m)

Extra words[ಬದಲಾಯಿಸಿ]

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)

Differences from templates previously used[ಬದಲಾಯಿಸಿ]

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.
  • The module does not have a problem with template loops, and will allow pointless conversions like {{convert|123|m|m}}.
  • 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.

Limitations[ಬದಲಾಯಿಸಿ]

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)
