Explanation
horsepower and kilowatts are units of power. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 horsepower = 0.7456998716 kilowatts, and 1 kilowatts = 1.3410220896 horsepower. Because one kilowatts represents a larger amount than one horsepower, the numeric value gets smaller in this direction.
How to convert horsepower to kilowatts
- Enter the value in horsepower (hp).
- Multiply it by 0.7456998716.
- The result is the equivalent value in kilowatts (kW).
- Round the result if needed.
