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
