Convert Kilowatts to Metric horsepower
1 kilowatt is 1.359622 PS. One kilowatt is exactly 1.3596216173 metric horsepower.
One kilowatt is 1.3596216 metric horsepower. To convert kilowatts to metric horsepower, multiply by 1.3596216; to go the other way, divide by 1.3596216 or multiply by 0.73549875. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand watts.

What is a kilowatt?
A thousand watts. Electric motors, kettles and EV chargers are rated here, and a kilowatt is close to 1.34 horsepower.
What is a metric horsepower?
Exactly 75 kilogram-force metres a second, which is 1.4% less than mechanical horsepower. A German car quoted at 150 PS is 148 hp, and the difference is the definition rather than the engine.
How many metric horsepower are in a kilowatt?
One kilowatt is 1.3596216 metric horsepower. Going the other way, one metric horsepower is 0.73549875 kilowatts. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
