Horsepower and kilowatts are both units used to measure power. Keep reading to learn more about each unit of measure.
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.
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).
