Kilowatts to horsepower

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.

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.

How to convert kilowatts to horsepower

Kilowatts to mechanic / hydraulic horsepower

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 kilowatts to horsepower is given by:

P_(hp)

= P_(kW) / 0.745699872

Example

Convert 10kW to mechanic horsepower:

P_(hp)

= 10kW / 0.745699872 = 13.41 hp

Kilowatts to electrical horsepower

One electrical horsepower is equal to 0.746 kilowatts:

1 hp(E) = 746 W = 0.746 kW

So the power conversion of kilowatts to horsepower is given by:

P_(hp) = P_(kW) / 0.746

Example

Convert 10kW to electrical horsepower:

P_(hp) = 10kW / 0.746 = 13.405 hp

Kilowatts to metric horsepower

One metric horsepower is equal to 0.73549875 kilowatts:

1 hp(M) = 735.49875 W = 0.73549875 kW

So the power conversion of kilowatts to horsepower is given by:

P_(hp) = P_(kW) / 0.73549875

Example

Convert 10kW to metric horsepower:

P_(hp) = 10kW / 0.73549875 = 13.596 hp
