# Cubic centimetre

A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm x 1 cm × 1 cm. One cubic centimetre corresponds to a volume of one millilitre. 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.

Cubic centimetre A measuring cup holding 1000 cubic centimetres, that is one litre (1 L) or 1000 millilitres (1000 mL)

In internal combustion engines, "cc" refers to the total volume of its engine displacement in cubic centimetres. The displacement can be calculated using the formula

$d={\pi \over 4}\times b^{2}\times s\times n$ where d is engine displacement, b is the bore of the cylinders, s is length of the stroke and n is the number of cylinders.
