## Using Online Converter :

To further proceed with this method, **Enter** the power in horsepower below to get the value converted to watts. Then you’ll see the results being display in the box.

## Using The Formula:

Here we’re using different types of horsepower for your choice.

### Mechanical Horsepower to Watts

Here the formula given to convert mechanical horsepower to watts:

watts = hp(I) × 745.699872

Since, 1 mechanical horsepower is equal to 745.699872 watts, the formula to find watts is to multiply mechanical horsepower by 745.699872.

Let’s take an example, here’s how to convert 3 mechanical horsepower to watts using the formula.

3 hp(I) = (3 × 745.699872) = 2237.099616 W

### Electric Horsepower to Watts

Here is the formula given to convert electric horsepower to watts

watts = hp(E) × 746

Since, 1 electric horsepower is equal to 746 watts, the formula to find watts is to multiply electric horsepower by 746.

For an example, here’s how to convert 5 electric horsepower to watts using the formula.

6 hp(E) = (6 × 746) = 4476 W

### Metric Horsepower to Watts

Formula given to convert metric horsepower to watts:

watts = hp(M) × 735.49875

Since, 1 metric horsepower is equal to 735.49875 watts, the formula to find watts is to multiply metric horsepower by 735.49875.

Have a look at the example, here’s **how to convert 5 metric horsepower to watts** using the formula.

4 hp(M) = (4 × 735.49875) = 2941.995 W

### Boiler Horsepower to Watts

We can use formula given below to convert boiler horsepower to watts:

watts = hp(S) × 9,809.5

Since, 1 boiler horsepower is equal to 9,809.5 watts, the formula to find watts is to multiply boiler horsepower by 9,809.5.

For example, how to convert 5 boiler horsepower to watts using the formula.

9 hp(S) = (9 × 9,809.5) = 88285.5 W
