Convert Watts to Horsepower (mechanical)

Watts → Horsepower (mechanical)
W × 0.001341022 = hp hp × 745.6999 = W

To convert watts (W) to horsepower (mechanical) (hp), multiply the watts value by 0.001341022. 1 W = 0.001341022 hp, and 1 hp = 745.6999 W. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert hp to W.
