Results in Milliwatts:
1 hp(E) = 746,000 mW

## How to Convert Electric Horsepower to Milliwatts Using an Easy Conversion Formula

Convert electric horsepower to milliwatts with this simple formula:

milliwatts = electric horsepower × 746,000

Converting an electric horsepower power measurement to a milliwatt measurement involves multiplying your power by the conversion ratio to find the result. An electric horsepower is equal to 746,000 milliwatts, so to convert simply multiply by 746,000.

For example:
5 hp(E) = (5 × 746,000) = 3,730,000 mW

Electric horsepower and milliwatts are both units used to measure power. Learn more about power and find more power measurement conversion calculators. An electric horsepower is a power measurement and can be abbreviated as hp(E), for example 1 hp(E). A milliwatt is a power measurement and can be abbreviated as mW, for example 1 mW.

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.
