Usage

{{convert|value|from-unit|to-unit|decimals|hide-unit}}

The parameters value, from-unit and to-unit are mandatory, and the other optional

value: Value to be converted from one unit to another.

from-unit: Unit to be converted from

to-unit: Unit to be converted to

decimals: Number of decimals. If empty, no decimals will be shown

hide-unit: If not empty the unit will not be shown in the result

Examples

m/s	meters per second
km/h	kilometers per hour
mph	statute miles per hour
kt	knots

Units of time
