How do you convert PS to kW?
Multiply the number of metric horsepower by 0.7355. This is the horsepower used in Germany as PS, in France as ch, in Spain and Italy as CV. A figure from an American source almost always uses the other horsepower.
PS = kW ÷ 0.7355

The metric horsepower is defined as 75 kilogram-force-metres per second, exactly 735.49875 W. It does not belong to the SI but remains tolerated in several European countries for commercial communication, provided the legal figure in kilowatts appears as well. Methodology & sources.
Frequently asked questions
Why isn't 150 PS the same as 150 hp?
Because they are two different units sharing one everyday name. 150 PS is 110.3 kW, 150 hp is 111.9 kW. Translated across, 150 PS equals 148 hp. The 1.4 % gap comes from the definitions: 75 kgf·m/s on one side, 550 ft·lbf/s on the other.
What is the difference between horsepower and tax horsepower?
No relation at all. Metric horsepower measures mechanical power. Tax horsepower is a number computed by the authorities from power and sometimes CO2 emissions, purely to set a levy. A 150 PS car may be rated 8 tax horsepower.
What is the exact factor?
0.73549875, rounded to 0.7355 in our tables. For the reverse, multiply kilowatts by 1.35962. Remembering 0.74 is enough in conversation: the error stays below one horsepower up to 150 PS.
Are motorcycles rated in horsepower too?
Yes, on a different scale: a 125 scooter makes around fifteen horsepower or 11 kW, a touring bike 100 PS or 73.5 kW, a race-derived sportbike passes 200 PS. The European A2 licence caps at 35 kW, which is 47.6 PS.
PS, CV, pk, hk: are they all the same horsepower?
Yes, every one of them is 735.5 W. The metric horse is written PS in Germany and Austria, ch in France, CV in Spain, Italy and Portugal, pk in the Netherlands, hk in the Nordic countries, ks in central Europe and 馬力 in Japan. A Japanese or Korean figure given in PS is therefore directly comparable with a German one. Only the Anglo-Saxon hp stands apart, at 745.7 W.
