**Conversion of units** is the conversion between different units of measurement for the same quantity, typically through multiplicative **conversion factors** which change the measured quantity value without changing its effects. Unit conversion is often easier within the metric or the SI than in others, due to the regular 10-base in all units and the prefixes that increase or decrease by 3 powers of 10 at a time.
