How to convert power in horsepower (hp) to watts (W).
Mechanic / Hydraulic horsepower to watts
One mechanic or hydraulic horsepower is equal to 745.699872 watts:
1 hp(I) = 745.699872 W
So the power conversion of horsepower to watts is given by:
P(W) = 745.699872 ⋅ P(hp)
Example
Convert 10 hp to watts:
P(W) = 745.699872 ⋅ 10hp = 7456.99872 W
Electrical horsepower to watts
One electrical horsepower is equal to 746 watts:
1 hp(E) = 746 W
So the power conversion of horsepower to watts is given by:
P(W) = 746 ⋅ P(hp)
Example
Convert 10 hp to watts:
P(W) = 746 ⋅ 10hp = 7460 W
Metric horsepower to watts
One metric horsepower is equal to 735.49875 watts:
1 hp(M) = 735.49875 W
So the power conversion of horsepower to watts is given by:
P(W) = 735.49875 ⋅ P(hp)
Example
Convert 10 hp to watts:
P(W) = 735.49875 ⋅ 10hp = 7354.9875 W
