How to Convert Foot-pound per Second to Metric Horsepower
- 1 ft·lbf/s = 0.001843399392 PS
- 1 PS = 542.4760388 ft·lbf/s
- Example: convert 15 ft·lbf/s to PS: 15 ft·lbf/s = 15 × 0.001843399392 PS = 0.02765099088 PS
Formula
PS = ft·lbf/s × 0.00184339939168
or PS = ft·lbf/s ÷ 542.4760388407
Derivation from SI units:
- 1 ft·lbf/s = 1.3558179483314 W
- 1 PS = 75 kgf·m/s = 735.49875 W (exact)
- 1 ft·lbf/s = 1.355817948331 W ÷ 735.49875 W per PS = 0.00184339939168 PS
Both units are defined exactly, so the factor is exact. Foot-pound per Second definition: foot-pound per second; Metric Horsepower definition: metric horsepower.
Worked examples
- A reading of 100 ft·lbf/s converts to 0.1843399392 PS.
100 ft·lbf/s × 0.001843399392 = 0.1843399392 PS - A value of 1000 ft·lbf/s is 1.843399392 PS.
1000 ft·lbf/s × 0.001843399392 = 1.843399392 PS
