Definition

1 cm³ = (0.01 m)³ = exactly 10^-6 m³ = exactly 1 mL.

Reference value

One cubic centimetre is exactly 0.000001 cubic metres.

History & use

A coherent SI-derived volume formed by cubing the centimetre; since 1964 the litre is defined as exactly 1 dm³, so 1 cm³ equals 1 mL exactly.

Modern use

Common in medicine (doses written as cc), engine displacement, laboratory work and densities in g/cm³. Same quantity as the millilitre, which remains its own record.

Did you know?

A cubic centimetre and a millilitre are the same volume under two names: one is a cube's edge, the other a thousandth of a litre.
