How to Convert Kilowatt to Foot-pound per Second
- 1 kW = 737.5621493 ft·lbf/s
- 1 ft·lbf/s = 0.001355817948 kW
- Example: convert 15 kW to ft·lbf/s: 15 kW = 15 × 737.5621493 ft·lbf/s = 11063.43224 ft·lbf/s
Formula
ft·lbf/s = kW × 737.5621492773
Derivation from SI units:
- 1 kW = 10³ W
- 1 ft·lbf/s = 1.3558179483314 W
- 1 kW = 1000 W ÷ 1.355817948331 W per ft·lbf/s = 737.5621492773 ft·lbf/s
Both units are defined exactly, so the factor is exact. Kilowatt definition: kilowatt; Foot-pound per Second definition: foot-pound per second.
Worked examples
- A reading of 3.5 kW converts to 2581.467522 ft·lbf/s.
3.5 kW × 737.5621493 = 2581.467522 ft·lbf/s - A value of 22 kW is 16226.36728 ft·lbf/s.
22 kW × 737.5621493 = 16226.36728 ft·lbf/s
