Metric system

Decimal-based systems of measurement

A system of measurement is a frame in which physical qualities (such as length, weight, temperature, etc.) can be quantified with numbers. Among many systems of measurement, the metric system refers to ones, each standardises a set of base units and a nomenclature describing relatively large and small quantities using decimal-based multiplicative unit prefixes (such as kilo and milli). The International System of Units (SI) is a good example, and there are other widely accepted systems (less popular than SI) mainly used in specific fields, such as the Gaussian units for electromagnetism.
