How to Convert Milliwatts to Electric Horsepower

To convert a milliwatt measurement to a electric horsepower measurement, multiply the power by the conversion ratio. One milliwatt is equal to 1.3405E-6 electric horsepower, so use this simple formula to convert:

electric horsepower = milliwatts × 1.3405E-6

The power in electric horsepower is equal to the milliwatts multiplied by 1.3405E-6.

For example, here's how to convert 5 milliwatts to electric horsepower using the formula above.
5 mW = (5 × 1.3405E-6) = 6.7024E-6 hp(E)

Milliwatts and electric horsepower are both units used to measure power. Keep reading to learn more about each unit of measure.

Milliwatts

One milliwatt is the power equal to 1/1,000 of a watt, or the energy consumption at a rate of 1/1,000 of a joule per second.

The milliwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "milli" is the prefix for 10-3. Milliwatts can be abbreviated as mW, for example 1 milliwatt can be written as 1 mW.

Electric Horsepower

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).
