Cubic centimeters cannot be converted to horsepower because they are two different units of measurement. Cubic centimeters is the standard unit of volume used in the International System of Units. Horsepower is a unit of energy commonly used to describe the engine of a vehicle.
A cubic centimeter is equivalent to a cube with all sides measuring 1 centimeter. One horsepower, when converted to the same system of units as a cubic centimeter, is equal to 746 watts when used to describe electrical energy. Horsepower was first used by James Watt to describe the amount of work a horse can do in 1 minute.
