    The metric system is a decimal -based system of measurement. The current international standard for the metric system is the International System of Units (Système international d'unités or SI), in which all units can be expressed in terms of seven base units: the metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and ...

    For example, driving distances are normally given in kilometres (symbol km) rather than in metres. Here the metric prefix ' kilo- ' (symbol 'k') stands for a factor of 1000; thus, 1 km = 1000 m . The SI provides twenty-four metric prefixes that signify decimal powers ranging from 10 −30 to 10 30 , the most recent being adopted in 2022.

    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres (⁠100⁠m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
