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.
Mechanical horsepower — 33,000 ft·lbf/min, or 550 ft·lbf/s (745.700 watts or 0.745700 kW)
Metric horsepower — 75 kgf·m/s ((735.499 W or 0.735499 kW)
Electrical horsepower — 0.746 kW (746 W)
Boiler horsepower — 9.8095 kW (9809.5 W)
Hydraulic horsepower — merely mechanical horsepower; can be calculated by multiplying the specific units of US gal/min times pressure in psi (lbf/in²) then dividing by 1714.
Additionally, the term "horsepower" has been applied to calculated (estimated rather than measured) metrics:
RAC horsepower is based solely on the dimensions of a piston engine (1 liter of engine displacement is equal to 10 RAC horsepower)
