Brake horsepower per cubic centimeter

Brake horsepower per cubic centimeter or (bhp/cc) is a ratio that is used to measure the power to size ratio of combustion engines. The BHP is the net power output of the engine at its rated speed and full throttle; CC is the engine displacement, calculated in metric units.

A similar measure is kilowatt per liter (kw/l) this term was first used by André Erasmus and Morné Basson. It is equivalent to bhp/cc when the appropriate conversion factors are employed on the upper and lower terms of the ratio.
