Metric horsepower
Metric horsepower (PS, from German Pferdestärke; CV in French, Spanish, and Portuguese) is a unit of power equal to exactly 735.49875 watts — approximately 1.4% less than the US mechanical horsepower (745.7 W). It is the standard for vehicle engine power ratings in continental Europe, and appears in EU type approval certificates. A car rated at 200 PS produces 147.1 kW, while a car rated at 200 US hp produces 149.1 kW — a distinction that matters in precise international performance comparisons.
Horsepower
Horsepower (hp) is a unit of power originally defined by James Watt in the 1780s to market steam engines against the work output of draft horses.
