How to Convert Mechanical Horsepower to Kilowatts

Convert mechanical horsepower to kilowatts with this simple formula:

kilowatts = mechanical horsepower × 0.7457

Converting a mechanical horsepower power measurement to a kilowatt measurement involves multiplying the power by the conversion ratio to find the result. One mechanical horsepower is equal to 0.7457 kilowatts, so to convert simply multiply by 0.7457.

For example, here's how to convert 5 mechanical horsepower to kilowatts using the formula above.
5 hp(I) = (5 × 0.7457) = 3.728499 kW

Mechanical horsepower and kilowatts are both units used to measure power. Learn more about power and find more power measurement conversion calculators. Mechanical horsepower is a power measurement and can be abbreviated as hp(I), for example 1 hp(I). Kilowatts are a power measurement and can be abbreviated as kW, for example 1 kW.

Mechanical horsepower is often used to measure the output of engines and motors in North America and is equal to 745.69987158227022 watts, or joules per second. Electric horsepower is used to measure the output of electric motors and other electrical machines, and is equal to exactly 746 watts.
