Horsepower to Kilowatt Formula
The following formula is used to convert horsepower to kilowatts.
Variables:
- kW is the power in kilowatts
- hp is the power in mechanical horsepower
For mechanical horsepower, multiply by approximately 0.745699872 to obtain kilowatts. Metric horsepower uses 0.73549875 kW per PS. Select the input and output units above.
What is Horsepower?
Horsepower is a unit of power in the British system of measurement. It is commonly used to measure the power of engines and motors. One mechanical horsepower is 550 foot-pounds-force per second, or 33,000 foot-pounds-force per minute.

| 60 | 44.742 |
| 75 | 55.927 |
| 100 | 74.570 |
| Conversion factor: 1 mechanical horsepower = approximately 0.745699872 kW. Note: metric horsepower differs slightly (1 PS = 0.73549875 kW). | |
What is a Kilowatt?
A kilowatt (kW) is a unit of power in the International System of Units (SI). It is equivalent to one thousand watts. Power in kilowatts is often used to express the output of engines and the power of electric motors, tools, machines, and heaters.
How to Convert Horsepower to Kilowatts?
The following steps outline how to convert horsepower to kilowatts.
- First, determine the power in horsepower (hp).
- Next, use the conversion formula: kW ≈ hp(mechanical) * 0.745699872.
- Finally, calculate the power in kilowatts (kW).
- After inserting the horsepower value and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variable as an example problem to test your knowledge.
power in horsepower (hp) = 100 hp
The result in kilowatts is 74.570 kW.
