What is Foot-pound per second?
The foot-pound per second is the fundamental unit of power in the imperial system, representing one foot-pound of work performed per second. It equals approximately 1.356 watts. Historically, James Watt defined one horsepower as 550 foot-pounds per second, making this unit the foundation of the horsepower concept. While rarely used directly in modern practice, it appears in engineering unit conversions and historical technical literature.
What is Metric horsepower?
Metric horsepower (PS) is defined as the power to lift 75 kilograms by one meter in one second, equal to approximately 735.5 watts. The abbreviation comes from the German "Pferdestärke" (horse strength). It is the standard unit for automotive power in Japan, Germany, and much of continental Europe. Japanese car specifications typically list maximum output in PS. One PS is slightly less than one mechanical horsepower (hp).
