Template:Convert/list of units

The table below lists units supported by {{convert}}. More complete lists are linked for each dimension. For a complete list of all dimensions, see full list of units.

{{Convert}} uses unit-codes, which are similar to, but not necessarily exactly the same as, the usual written abbreviation for a given unit. These unit-codes are displayed in column 3 of the following tables. These are accepted as input by {{convert}} as the second and third unnamed parameters:

• {{convert|100|kg|lb}} → 100 kilograms (220 lb)
• {{convert|100|lb|kg}} → 100 pounds (45 kg)

The unit-codes should be treated as case-sensitive:

• {{convert|100|Mm|mm}} → 100 megametres (1.0×10¹¹ mm)

The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination output units are listed below in column 7.

• {{convert|55|nmi|km mi}} → 55 nautical miles (102 km; 63 mi)
• {{convert|1|oz|ozt g gr}} → 1 ounce (0.91 ozt; 28 g; 440 gr)

Some units have alternative unit-codes. These are shown in brackets in column 3, e.g. °F (F). Either may be entered for Fahrenheit (but not a lower-case f).
