How many horsepower is 100 kilowatts?
About 136 in metric horsepower, 134 in mechanical. Estonian documents and the European motor industry use metric horsepower, so a 100 kW engine is 136 hp here. For mental arithmetic, multiply kilowatts by 1.36.
Why are there two kinds of horsepower?
Mechanical horsepower comes from the British system and is defined through foot-pounds; the metric one through kilogram-metres. The gap is about 1.4 percent, which on a car amounts to a couple of horsepower — small enough to go unnoticed, large enough to confuse when comparing spec sheets.
