Some SI units of volume to scale and approximate corresponding mass of water
Acubic centimetre (orcubic centimeterin US English) (SI unit symbol:cm3; non-SI abbreviations:cc andccm) is a commonly usedunit ofvolume that corresponds to the volume of acube that measures 1 cm × 1 cm × 1 cm. One cubiccentimetre corresponds to a volume of onemillilitre. The mass of one cubic centimetre of water at 3.98 °C (the temperature at which it attains itsmaximum density) is almost equal to one gram.
