The conversion formula for cubic inches (cu in) to cubic centimetres (cu cm) conversions is as follows:
The cubic centimetre is a unit of volume, its size is that of a cube with sides of one centimetre. It is most well known as the measure of car engine size (cc).
SI Metric
The cubic centimetre is defined as the volume enclosed by a cube with edges of one centimetre in length.
Metre
Formal: cm3
The abbreviations cc, ccm, cu cm, cu centimetre and cubic cm are also used.
The cubic centimetre is an SI metric unit of volume, it is one millionth (1/1000000) of a cubic metre. A cubic centimetre is the same size as the millilitre, being one thousandth (1/1000) of a litre.
In many applications, especially involving liquids, the millilitre is more common than the cubic centimetre.
The most common use of the cubic centimetre has been for measuring the size of automobile engines (e.g. 1300cc, 1998cc). The value measured is the engine displacement which is the volume that is covered by the movement of the top of the piston from its lowest position in the cylinder to its highest position in the cylinder.
Cubic centimetres are used worldwide, although they are not standard units in the United States and Liberia. The use of cubic centimetres is not consistent, even in countries that use the metric system, with millilitres also in day to day use.
The cubic inch is an Imperial unit of volume that has the size of a cube with edges of one inch in length. It is often used for measuring engine size in the USA.
Imperial & US Customary
The cubic inch is defined as the unit of volume contained within a cube with edges of one inch.
Yard
Formal: in3
The following abbreviations have all been used for cubic inches cu in, cu ins, inch3, cubic in, cubic ins, cu inch, cu inches, c.i., CI and cui.
The cubic inch is derived from the inch, which in turn is derived from the formal definition of the yard. A cubic inch is 1/46656th of a cubic yard.
Cubic inches were the standard measure of engine size in the USA until fairly recently when the litre became more widespread and have also been used for measuring engine size in the UK before the adoption of the metric systems by some manufacturers.

Cubic inches are a standard unit of volume in the United States and Liberia and are still found occasionally in the United Kingdom and other British Commonwealth countries that formerly used Imperial units as standard.
