Horsepower

Horsepower (hp) is a unit of power. Power is the rate of energy usage per time unit. One imperial/mechanical horsepower (hp) is equal to 745.699872 watts (W). One metric horsepower (hp) is equal to 735.49875 watts (W).

Kilowatt

Kilowatt (kW) is a unit of power. Power is the rate of energy usage per time unit. One kilowatt (kW) is equal to 1000 watts (W). One kilowatt (kW) is equal to 1000 joules (J) per second (S).

How to convert horsepower to kilowatts

Imperial/Mechanic horsepower to kilowatts

One imperial/mechanic 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
