Conversion of horsepower and kilowatts

There are different coefficients to determine the number of watts depending on horsepower.

  • Metric horsepower equals to 735,49875 W. Mostly this value is used in calculations.
  • Mechanical (Imperial) horsepower equals to 745,69987158227022 W.
  • Electrical horsepower equals to 746 W.
  • Boiler horsepower equals to 9812,5 W.

It should be borne in mind that the coefficients are in watts and calculations are in kilowatts, so the coefficients are divisible by 1000.
