1 kW = 1.341 hp
mechanical horsepower
1 kW = 1.341 hp
How to convert kilowatts to mechanical horsepower
Multiply the number of kilowatts by 1.3410221.
Formula
hp = kW × 1.3410221
The factor is rounded; the converter uses the full-precision value.
Examples
- 75 kW × 1.3410221 = 100.5767 hp
- 110 kW × 1.3410221 = 147.5124 hp
- 300 kW × 1.3410221 = 402.3066 hp

About kilowatts
A kilowatt is 1,000 watts. Engine power in Europe, heat pumps, solar panels and EV chargers are rated in kilowatts.
About mechanical horsepower
Mechanical horsepower, also called imperial horsepower, is defined as 550 foot-pounds-force per second, about 745.7 watts. US and UK car engine ratings in "hp" or "bhp" use this definition.
Frequently asked questions
How many mechanical horsepower are in one kilowatt?
One kilowatt equals 1.341 mechanical horsepower (rounded).
How do I convert kilowatts to mechanical horsepower?
Multiply the number of kilowatts by 1.3410221. For example: 110 kW × 1.3410221 = 147.5124 hp.
How many kilowatts are in one mechanical horsepower?
One mechanical horsepower equals 0.7457 kilowatts.
Is the kW to hp conversion exact?
The factor between these units has more decimals than are useful to show, so it is rounded on this page. The converter itself always calculates with the full-precision value.
My European car manual lists PS, not hp. Which do I use?
PS is metric horsepower (735.5 W), slightly smaller than mechanical hp (745.7 W). Choose "Metric horsepower (PS)" in the converter to get PS from kW.
