### 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
