A centimetre (international spelling as used by the International Bureau of Weights and Measures; symbol cm) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a metre, centi being the SI prefix for a factor of 1/100.
The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units |
