How to Convert Microwatts to Mechanical Horsepower

To convert a microwatt measurement to a mechanical horsepower measurement, multiply the power by the conversion ratio. One microwatt is equal to 1.341E-9 mechanical horsepower, so use this simple formula to convert:

mechanical horsepower = microwatts × 1.341E-9

The power in mechanical horsepower is equal to the microwatts multiplied by 1.341E-9.

For example, here's how to convert 5 microwatts to mechanical horsepower using the formula above.
5 µW = (5 × 1.341E-9) = 6.7051E-9 hp(I)

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


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

The microwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "micro" is the prefix for 10-6. Microwatts can be abbreviated as µW, for example 1 microwatt can be written as 1 µW.

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).
