What is Pferdestärke (ps)?

Pferdestärke (PS) is a metric horsepower unit historically used in German-speaking countries to measure mechanical power, defined as 75 kilogram-force metre per second.

What does horsepower (550 ft*lbf/s) represent?

Horsepower (550 ft*lbf/s) is an imperial unit of power defined as 550 foot-pound-force per second, representing mechanical horsepower as defined by James Watt.

Why convert Pferdestärke to horsepower?

Converting Pferdestärke to horsepower allows consistent comparison and specification of power ratings across metric-based German units and imperial units used internationally.
