# Convert Electric Horsepower to Milliwatts

Enter the power in electric horsepower below to get the value converted to milliwatts.

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

## How to Convert Electric Horsepower to Milliwatts

To convert a electric horsepower measurement to a milliwatt measurement, multiply the power by the conversion ratio. One electric horsepower is equal to 746,000 milliwatts, so use this simple formula to convert:

milliwatts = electric horsepower × 746,000

The power in milliwatts is equal to the electric horsepower multiplied by 746,000.

For example, here's how to convert 5 electric horsepower to milliwatts using the formula above.
5 hp(E) = (5 × 746,000) = 3,730,000 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).

## 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.
