How to convert power in horsepower (hp) units to kilowatts (kW) units.
Mechanic / Hydraulic horsepower to kilowatts
One mechanic or hydraulic horsepower is equal to 0.745699872 kilowatts:
1 hp(I) = 745.699872 W = 0.745699872 kW
So the power conversion of horsepower to kilowatts is given by:
P(kW) = 0.745699872 · P(hp)
Example
Convert 10 hp to kW:
P(kW) = 0.745699872 · 10hp = 7.45699872 kW
Electrical horsepower to kilowatts
One electrical horsepower is equal to 0.746 kilowatts:
1 hp(E) = 746 W = 0.746 kW
So the power conversion of horsepower to kilowatts is given by:
P(kW) = 0.746 · P(hp)
Example
Convert 10 hp to kW:
P(kW) = 0.746 · 10hp = 7.460 kW
Metric horsepower to kilowatts
One metric horsepower is equal to 0.73549875 kilowatts:
1 hp(M) = 735.49875 W = 0.73549875 kW
So the power conversion of horsepower to kilowatts is given by:
P(kW) = 0.73549875 · P(hp)
Example
Convert 10 hp to kW:
P(kW) = 0.73549875 · 10hp = 7.3549875 kW
