Formula
mW to hp(I) conversion formula
Use this relationship for a direct conversion:
Worked example
2 mW = 0.000002682 hp(I).
Horsepower type is always identified because mechanical and metric horsepower differ by about 1.4 percent.
Power conversion
1 milliwatt (mW) equals 0.000001341022 mechanical horsepower (hp(I)). Enter any value below to convert from mW to hp(I).
