## 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:

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.

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).
