Online Converter: Horsepower (hp) - Kilowatt (kW)

Car manufacturers and dealers are nowadays required by law to indicate the power of their cars in kilowatts (kW). However, most people still have more understanding of the in the meantime outdated unit called horsepower (hp).

With our online calculator you can convert kW values ​​into hp or vice versa, horsepower figures into kilowatts. To do this, simply enter a horsepower value or a kilowatt value into the respective input field. The calculator will then automatically show you the converted value in the other field.

Definition of the Horsepower

The horsepower is an old unit that goes back to James Watt. It was intended to demonstrate how many horses could replace a machine. The average power of such a workhorse was defined as 0.73549875 kW, which makes it possible to convert kilowatts and horsepower into each other. One kilowatt therefore corresponds to 1/0.73549875 hp, what is approximately 1.35962162 hp.

1 kW equals 1.35962162 hp
1 hp equals 0.73549875 kW
