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 × 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 almost equal to one gram.

One complete cycle of a four-cylinder, four-stroke engine. The areas marked in orange represent the displaced volumes.

Some SI units of volume to scale and approximate corresponding mass of water

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

${\displaystyle d={\pi \over 4}\times b^{2}\times s\times n}$

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.
