Convert HP to kW


What is Horsepower?

Horsepower (HP) is a unit of measurement for power, the rate at which work is done. Originally devised by engineer James Watt to compare the power of steam engines with the work of draft horses, it has since become a standard unit for measuring the power output of engines, motors, and other machinery. One horsepower is defined as the ability to move 550 pounds one foot in one second, or 33,000 foot-pounds per minute.
