About converting Metric Horsepower to Watts
Metric Horsepower (PS) and Watts (W) are both units of power, so converting between them is a single multiplication: multiply your Metric Horsepower figure by 735.4988. Ten Metric Horsepower comes to 7,354.99 Watts, and a hundred works out at 73,549.88 Watts.
Rule of thumb: going from Metric Horsepower to Watts multiplies, so the figure always grows — one Metric Horsepower is already 735.4988 Watts. If your answer came out smaller, you have the conversion the wrong way round.
What is a Metric Horsepower?
Metric horsepower is why the same car is advertised with two different "horsepower" numbers depending on which side of the Atlantic you read about it. It is defined as exactly 75 kilogram-force metres per second, which makes it slightly smaller than the mechanical horsepower used in Britain and America — so the European figure for an identical engine always comes out a little higher, and neither number is wrong. It is written PS in Germany, from Pferdestärke, and turns up as CV or hk elsewhere. Enthusiast arguments about a car’s "real" output are very often just this unit mismatch.
What is a Watt?
The watt is the SI unit of power — one joule per second — named after James Watt, whose steam-engine improvements did as much as anything to make the idea of power commercially interesting. It measures a rate, not an amount: a watt tells you how fast energy is being moved or converted and says nothing on its own about how much has been used. That is the entire difference between the watts printed on a light bulb and the kilowatt-hours printed on the bill. It is also deliberately universal — the same unit rates a bulb, a loudspeaker, an engine, a laser and a cyclist on a hill.
To put both in perspective: a hot hatch might be advertised at 200 PS in Germany, while an LED bulb bright enough for a room draws about 10 watts.
