How to Convert Horsepower to Kilowatts
To convert horsepower to a kilowatt measurement, use one of the formulas below.
Mechanical Horsepower to Kilowatts
Formula to convert mechanical horsepower to kilowatts:
kilowatts = hp(I) × 0.7457
Since one mechanical horsepower is equal to 0.7457 kilowatts, the formula to find kilowatts is to multiply mechanical horsepower by 0.7457.
Electric Horsepower to Kilowatts
Formula to convert electric horsepower to kilowatts:
kilowatts = hp(E) × 0.746
Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746.
Metric Horsepower to Kilowatts
Formula to convert metric horsepower to kilowatts:
kilowatts = hp(M) × 0.735499
Since one metric horsepower is equal to 0.735499 kilowatts, the formula to find kilowatts is to multiply metric horsepower by 0.735499.
Boiler Horsepower to Kilowatts
Formula to convert boiler horsepower to kilowatts:
kilowatts = hp(S) × 9.8095
Since one boiler horsepower is equal to 9.8095 kilowatts, the formula to find kilowatts is to multiply boiler horsepower by 9.8095.
How Many Kilowatts Are in a Horsepower?
There are 0.7457 kilowatts in a horsepower, which is why we use this value in the formula above.

There are several types of horsepower, including mechanical, electrical, metric, boiler, brake, and indicated, and they all have different applications in industry. Mechanical and electrical are the most commonly used.
Mechanical horsepower is often used to measure the output of engines and motors in North America. One mechanical horsepower is equal to 745.69987158227022 watts.
The mechanical horsepower is a US customary and imperial unit of power. Mechanical horsepower can be abbreviated as hp(I); for example, 1 mechanical horsepower can be written as 1 hp(I).
Electric horsepower is used to measure the output of electric motors and other electrical machines in the US. One electric horsepower is equal to exactly 746 watts.
The electric horsepower is a US customary and imperial unit of power. Electric horsepower can be abbreviated as hp(E); for example, 1 electric horsepower can be written as 1 hp(E).
The metric horsepower is a non-SI metric unit for power. Metric horsepower can be abbreviated as hp(M), and are also sometimes abbreviated as PS, cv, hk, pk, ks, or ch. For example, 1 metric horsepower can be written as 1 hp(M), 1 PS, 1 cv, 1 hk, 1 pk, 1 ks, or 1 ch.
Boiler horsepower can be abbreviated as hp(S); for example, 1 boiler horsepower can be written as 1 hp(S).
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.
