How to Convert Watt to Horsepower (electric)

1 watt = 0.00134048 horsepower (electric) exact

Horsepower (electric) = Watt × 0.00134048

Example: 1500 W × 0.00134048 = 2.0107 hp(E)

Reverse Conversion

To convert horsepower (electric) back to watts:

  • Remember, 1 horsepower (electric) equals 746 watts.
  • To convert 2.0107 hp(E) to W, multiply 2.0107 x 746, resulting in 1500 W.

exact This conversion factor is exact by international definition.

1500 W is also equal to:

  • 1 12 kilowatt
  • 0.0015 megawatt
