A kilowatt (kW) is 1,000 watts, used for electric motors, appliances and official engine ratings in Europe.
Metric horsepower (PS) is about 735.5 W, roughly 1.4% less than mechanical horsepower. Car specs in Korea, Japan and Europe usually quote PS.
kW × 1.36. For 5 kW that gives about 6.8 PS instead of 6.798 PS (0.028% too high).
