About Foot-Pounds per Minute
One foot-pound per minute (ft·lbf/min) ≈ 0.02260 W. Its historical importance is large: James Watt rated mill horses at ~33,000 ft·lbf/min sustained output and defined 1 mechanical horsepower as exactly 33,000 ft·lbf/min (= 550 ft·lbf/s). The unit is still used for machine-tool power, hydraulic pump output, and low-speed actuator performance in US customary calculations: torque (ft·lbf) × RPM = power in ft·lbf/min. 1 hp = 33,000 ft·lbf/min.
About Metric Horsepower
The metric horsepower (PS/CV/pk) equals exactly 75 kgf·m/s = 735.49875 W - the European equivalent of mechanical horsepower, defined as lifting 75 kg by 1 m/s. It was the DIN 66036 standard for European automotive ratings until the EU mandated kW. A 100 PS car produces 73.55 kW; 200 PS = 147.1 kW. The ~1.4% difference from mechanical hp (745.7 W) means a 100 PS car rates as 98.6 mechanical hp. German car advertising still shows PS parenthetically alongside kW. 1 PS = 735.49875 W.
