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:
