'''Conversion of units''' is the conversion of the [[unit of measurement]] in which a [[quantity]] is expressed, typically through a multiplicative '''conversion factor''' that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.

Unit conversion is often easier within a [[metric system]] such as the [[International System of Units|SI]] than in others, due to the system's [[Coherence (units of measurement)|coherence]] and its [[metric prefix]]es that act as power-of-10 multipliers.
