How to Convert Metric Horsepower to Kilowatt
- 1 PS = 0.73549875 kW
- 1 kW = 1.359621617 PS
- Example: convert 15 PS to kW: 15 PS = 15 × 0.73549875 kW = 11.03248125 kW
Formula
kW = PS × 0.73549875
or kW = PS ÷ 1.359621617304
Derivation from SI units:
- 1 PS = 75 kgf·m/s = 735.49875 W (exact)
- 1 kW = 10³ W
- 1 PS = 735.49875 W ÷ 1000 W per kW = 0.73549875 kW
Both units are defined exactly, so the factor is exact. Metric Horsepower definition: metric horsepower; Kilowatt definition: kilowatt.
Worked examples
- A 150 PS engine produces 110.3248125 kW.
150 PS × 0.73549875 = 110.3248125 kW - A 75 PS engine produces 55.16240625 kW.
75 PS × 0.73549875 = 55.16240625 kW
