The ''horsepower'' (abbreviated hp) is the power that an average [[horse]] could exert. One horsepower is 550 foot-pounds per second. Engines and motors often have their power rated in horsepower, as a direct measure of the size of a team of horses that would be required to match that engine or motor for power.
