How to Convert Metric Horsepower to Foot-pound per Second
- 1 PS = 542.4760388 ft·lbf/s
- 1 ft·lbf/s = 0.001843399392 PS
- Example: convert 15 PS to ft·lbf/s: 15 PS = 15 × 542.4760388 ft·lbf/s = 8137.140583 ft·lbf/s
Formula
ft·lbf/s = PS × 542.4760388407
Derivation from SI units:
- 1 PS = 75 kgf·m/s = 735.49875 W (exact)
- 1 ft·lbf/s = 1.3558179483314 W
- 1 PS = 735.49875 W ÷ 1.355817948331 W per ft·lbf/s = 542.4760388407 ft·lbf/s
Both units are defined exactly, so the factor is exact. Metric Horsepower definition: metric horsepower; Foot-pound per Second definition: foot-pound per second.
Worked examples
- A reading of 100 PS converts to 54247.60388 ft·lbf/s.
100 PS × 542.4760388 = 54247.60388 ft·lbf/s - A value of 200 PS is 108495.2078 ft·lbf/s.
200 PS × 542.4760388 = 108495.2078 ft·lbf/s
