HORSEPOWER

n. unit for measuring the rate of work of an engine or motor

This article is about a unit of measurement. For the machine which used horses to generate power, see horse power (machine). For other uses of hp, see HP (disambiguation)Horsepower (hp) is the name of several non-metric units of power. The most occurring conversion of horsepower to watt goes 1 horsepower = 745.7 watts. In scientific discourse, the term "horsepower" is seen as inferior and is rarely used because of its various definitions and the already existent SI unit for power, the watt (W). However, use of the term "horsepower" persists as a legacy in many languages and industries, particularly in the automotive industry because of their continued advertising of maximum power output of internal-combustion engines in "horsepower" units of measurement.
