How to convert power in watts (W) to horsepower (hp).
Watts to mechanic / hydraulic horsepower
One mechanic or hydraulic horsepower is equal to 745.699872 watts:
1 hp(I) = 745.699872 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 745.699872
Example
Convert 10W to mechanic horsepower:
P(hp) = 10W / 745.699872 = 0.01341 hp
Watts to electrical horsepower
One electrical horsepower is equal to 746 watts:
1 hp(E) = 746 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 746
Example
Convert 10W to electrical horsepower:
P(hp) = 10W / 746 = 0.013405 hp
Watts to metric horsepower
One metric horsepower is equal to 735.49875 watts:
1 hp(M) = 735.49875 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 735.49875
Example
Convert 10W to metric horsepower:
P(hp) = 10W / 735.49875 = 0.013596 hp
