BHP, PS and kW calculator

Convert a car power figure between brake horsepower (BHP), metric horsepower (PS) and kilowatts (kW).

Power figure Unit

BHP: 134.1
PS: 136
kW: 100

BHP, PS and kW are different units of power. This calculator converts the number only; it does not measure a vehicle’s engine output. Published figures may be rounded and can vary by trim, model year and market.

How the conversion works

One mechanical horsepower is approximately 0.7457 kW. One metric horsepower (PS) is approximately 0.7355 kW, so PS is slightly smaller than BHP. For example, 100 kW is about 134.1 BHP or 136.0 PS.
