A unit is any standard used for comparison in measurements. Unit conversions allow for measurements of a property that have been recorded using different units (e.g., centimeters to inches).

The meter is one standard of length. A liter is a standard of volume. Each of these standards can be used to compare with other measurements made using the same units.
