How to Convert Horsepower (electric) to Watt

1 horsepower (electric) = 746 watts exact

Watt = Horsepower (electric) × 746

Example: 12 hp(E) × 746 = 373 W

Reverse Conversion

To convert watts back to horsepower (electric):

  • Remember, 1 watt equals 0.00134048 horsepower (electric).
  • To convert 373 W to hp(E), multiply 373 x 0.00134048, resulting in 12 hp(E).

exact This conversion factor is exact by international definition.

12 hp(E) is also equal to:

  • 0.373 kilowatt
  • 0.000373 megawatt
