Horsepower to Kilowatts

The term horsepower was adopted by Scottish inventor James Watt to measure the power output of his steam engine and to compare that power with that of horses horses. Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.

There are now several different types of horsepower, including mechanical, electrical, metric, boiler, brake, and indicated, and they all have different applications in industry. Mechanical and electric are the most commonly used types.

One kilowatt is the power equal to 1,000 watts, or the energy consumption at a rate of 1,000 joules per second.

The kilowatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "kilo" is the prefix for 103. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.

How to convert horsepower to kilowatts

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

bSo 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
