What is HP to kW Calculator?

HP to kW Calculator helps you convert mechanical horsepower into kilowatts.

The main result is kilowatts. The formula, example and assumptions below explain how to interpret it.

How to use HP to kW Calculator

Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.

  1. Gather mechanical horsepower (hp). Use values from the same situation or reporting period.
  2. Replace the example mechanical horsepower with your own value, then complete the other fields. Check the displayed units.
  3. Select Calculate and read kilowatts. Change one input and calculate again to compare a second scenario. Reset restores the original example.
  • Enter mechanical horsepower in hp, at least 0. Decimals are accepted.
