A centimetre (American spelling: centimeter, symbol cm) is a unit of length in the metric system, equal to one hundredth of a metre, which is the current SI base unit of length. Centi is the SI prefix for a factor of 10. Hence a centimetre can be written as 10 × 10 m (engineering notation) or 1E−2 m (scientific E notation) — meaning 10 × 10 mm or 1 m/100 respectively,centimetre-gram-second system of units.

Though for many physical quantities, SI prefixes for factors of 10—like milli- and kilo-—are often preferred by technicians, the centimetre remains a practical unit of length for many everyday measurements. A centimetre is approximately the width of the fingernail of an adult person.
1 centimetre is equal to:
1 cubic centimetre is equal to 1 millilitre, under the current SI system of units.
In addition to its use in the measurement of length, the centimetre is used:
