Template:Convert/list of units

The table below lists units supported by this template. It is divided up according to the quantity being measured. Not all supported units are listed here; there are links to more complete lists for each quantity.

The codes listed in the code column (column 3) are accepted as input by the template. These can be used as the second or third unnamed parameter. For some units there exist alternative codes. These are listed in brackets and have been incorporated to make the code more flexible for editors, e.g. °F or F may be entered.

The codes listed in the combinations column (column 7) can be used to produce multiple conversions. They can only be used as the third unnamed parameter, e.g. {{convert|55|nmi|km mi}} produces "55 nautical miles (Template:Hid{{#invoke:Math|precision_format| 101.86 | 1-2 }} km;Template:Hid{{#invoke:Math|precision_format| 63.292869641295 | 1-1 }} mi)".
