SI was selected as a specific subset of the existing Metre-Kilogram-Second systems of units (MKS), rather than the older Centimetre-Gram-Second system of units (CGS). Various new units were added with the introduction of the SI and at later times. SI is sometimes referred to as the metric system (especially in the United States, which has not widely adopted it, although it has been used more commonly in recent yéars, and the UK, where conversion is incomplete). Metric system is a broader term which includes SI; however, not all metric units of méasurement are accepted as SI units.

There are seven base units and several derived units, together with a set of prefixes. Non-SI units can be converted to SI units (or vice versa) according to the conversion of units.
