A centimetre (Symbol cm ) is worth 10^-2 = 0,01 Mètre.

1 cm = 10^-2 m = 0,01 m;

1 m = 10² cm = 100 cm.

The centimetre is one of the basic units of the Système CGS. It makes it possible to define

• a unit of surface, the square centimeter (cm ²): one square centimeter is the surface of a Carré of 1 cm on side; it is worth ten-thousandths of Square meter
  1 cm ² = 10^{-2 × 2} m ² = 10^-4 m ² = 0,000  1 m ²
  1 m ² = 10^{2 × 2} cm ² = 10⁴ cm ² = 10  000 cm ²
• a unit of Volume, the Cubic centimeter (cm ³): one cubic centimeter is the volume of a Cube of 1 cm of stops; it is worth one millionth Cubic meter, and thousandths of Liter
  1 cm ³ = 10^{-2 × 3} m ³ = 10^-6 m ³ = 0,000  001 m ³
  1 m ³ = 10^{2 × 3} cm ³ = 10⁶ cm ³ = 1  000  000 cm ³
  1 cm ³ = 10^-3 L = 0,001 L
  1L = 10 ³ cm ³ = 1  000 cm ³.

Compared to the other units of length:

Use

The centimetre is of a popular use running: it makes it possible to represent in a simple way of dimensions of human size (lower than the meter). In the scientific discipline, one prefers the meter (basic unit of the international system) or the millimetre to him (very much used in mechanics) to represent the lengths of these orders of magnitude.
