How to Convert Watts to Electric Horsepower Using an Easy Conversion Formula

Convert watts to electric horsepower with this simple formula:

electric horsepower = watts × 0.00134

Converting a watt power measurement to an electric horsepower measurement involves multiplying your power by the conversion ratio to find the result. A watt is equal to 0.00134 electric horsepower, so to convert simply multiply by 0.00134.

For example:
5 W = (5 × 0.00134) = 0.006702 hp(E)

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

A watt is equal to the rate of energy of one joule per second and is a standard unit of power measurement under the International System of Units (SI). You might also find our watts to amps calculator or our watts to kilowatt-hours calculator useful.
