What is a Horsepower?
Horsepower is a marketing unit that became a standard. James Watt devised it to sell steam engines to mine owners who had never bought an engine but had bought plenty of horses: by measuring what a draught horse could actually lift over a working day, he could quote an engine as worth so many horses and let the buyer do the arithmetic. Mechanical or imperial horsepower is defined as exactly 550 foot-pounds-force per second, which is why it lands on no tidy figure in watts. Two and a half centuries after the horses left, it is still how cars, outboards and lawn tractors are advertised.
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.
To put both in perspective: a family hatchback makes something like 120 horsepower, while a hot hatch might be advertised at 200 PS in Germany.
