A
cubic centimetres (or
cubic centimeters in US English) (SI unit symbol:
cm3; non-SI abbreviations:
cc and
ccm) is a commonly used
unit of
volume that extends the derived
SI-unit
cubic metre, and corresponds to the volume of a cube that measures 1
cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of of a cubic metre, or of a
litre, or one
millilitre; thus, 1 cm
3 = 1 ml. The mass of one cubic centimetre of
water at 3.98 °C (the temperature at which it attains its
maximum density) is closely equal to one gram. Note that SI supports only the use of symbols and deprecates the use of any abbreviations for units. Hence
cm3 is preferred to
cc or
ccm.
