A unit of measurement is a defined magnitude of a particular quantity, which is used as a standard. Any other quantity of that same kind can be expressed as a multiple of the unit of measurement.

Measurement is the process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind.

Different systems of units are based on different choices of a set of base units. The most widely used system of units is the International System of Units, or SI (sometimes referred to as the Metric System).
