How to Convert Milliwatts to Mechanical Horsepower

To convert a milliwatt measurement to a mechanical horsepower measurement, multiply the power by the conversion ratio. One milliwatt is equal to 1.341E-6 mechanical horsepower, so use this simple formula to convert:

mechanical horsepower = milliwatts × 1.341E-6

The power in mechanical horsepower is equal to the milliwatts multiplied by 1.341E-6.

For example, here's how to convert 5 milliwatts to mechanical horsepower using the formula above.
5 mW = (5 × 1.341E-6) = 6.7051E-6 hp(I)

Milliwatts and mechanical 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.

Mechanical Horsepower

Mechanical horsepower is often used to measure the output of engines and motors in North America. One mechanical horsepower is equal to 745.69987158227022 watts.

The mechanical horsepower is a US customary and imperial unit of power. Mechanical horsepower can be abbreviated as hp(I), for example 1 mechanical horsepower can be written as 1 hp(I).
