Purpose

To show quantities in a primary and secondary display, such as 32 metres (105 ft), or 18 °C (64.4 °F).

Usage

{{convert|original_value|original_unit|conversion_unit|round_to}}

Examples

Input	Displays as
{{convert|32|m|ft|0}}	32 metres (105 ft)
{{convert|18|°C|°F|1}}	18 °C (64.4 °F)
{{convert|10|mi|km|0}}	10 miles (16 km)
{{convert|25|km|mi|0}}	25 kilometres (16 mi)
{{convert|1|lb|kg|0}}	1  ( )
{{convert|1250|sqft|sqm|1|lk=on}}	1,250 square feet (116.1 m²)
{{convert|20.5|sqkm|sqmi|1|lk=on|abbr=on}}	20.5 km² (7.9 sq mi)
{{convert|641|acre|sqmi|3|lk=on|abbr=on}}	641 acres (1.002 sq mi)
However
{{convert|641|acre|sqmi|2|lk=on|abbr=on}}	641 acres (1 sq mi) because 640 acres equals one square mile; 641 acres rounded to 2 would equal 1.00 sq mi. Therefore it is displayed as 1 sq mi.

Tricks

In order to...
Use U.S. spelling	attach |sp=us
Make units wikilinked	attach |lk=on (The manual of style suggests that you only link the first instance).
Use the singular for grammar	attach |sing=on (ex: "The 190 foot (58 m) bridge" as opposed to "feet")
Abbreviate all units	attach |abbr=on
Use a / instead ( )	attach |disp=slash (or shorthand: |disp=/) (ex: 190 foot/58 m)

Rounding

The number given for rounding rounds off the result to the power of 1/10 the rounding 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.

Conversions

The abbreviations to the right of the units are the abbreviations that can be entered when using the template. Through various revisions of this template, some units have incorporated multiple abbreviations to make the code more flexible for editors, e.g. °F or F may be entered. Though they may not be the correct abbreviations, the correct abbreviation will always be displayed when you use {{convert}}.
