g/cm³

gram per cubic centimeter

Densityexact by definition

The gram per cubic centimetre equals exactly 1000 kg/m³, since a gram is 10⁻³ kg and a cubic centimetre is 10⁻⁶ m³. The factor is exact. This is the unit most chemistry and materials tables use, because it makes water almost exactly 1 and therefore makes the number equal to the specific gravity.
