What is Metric Horsepower (PS)?

Metric horsepower (PS, CV) is a traditional unit of power used for engine output in Europe and much of the world; it equals 735.49875 watts. The mechanical horsepower (hp) used in the US and UK is slightly larger, 745.7 watts.

Short history of Metric Horsepower (PS)

Horsepower was introduced by James Watt in the 18th century to compare the output of steam engines with the work of draft horses; the metric version later became standard across the automotive industry outside the US.
