Results in Mechanical Horsepower:
1 hp(E) = 1.000402 hp(I)

## How to Convert Electric Horsepower to Mechanical Horsepower

To convert a electric horsepower measurement to a mechanical horsepower measurement, multiply the power by the conversion ratio. One electric horsepower is equal to 1.000402 mechanical horsepower, so use this simple formula to convert:

mechanical horsepower = electric horsepower × 1.000402

The power in mechanical horsepower is equal to the electric horsepower multiplied by 1.000402.

For example, here's how to convert 5 electric horsepower to mechanical horsepower using the formula above.
5 hp(E) = (5 × 1.000402) = 5.002012 hp(I)
