How to Convert Kilocalorie per Hour to Foot-pound per Second
- 1 kcal/h = 0.8577847796 ft·lbf/s
- 1 ft·lbf/s = 1.165793593 kcal/h
- Example: convert 15 kcal/h to ft·lbf/s: 15 kcal/h = 15 × 0.8577847796 ft·lbf/s = 12.86677169 ft·lbf/s
Reference conditions. kcal/h: Uses the International Table kilocalorie (4186.8 J), the convention in heating and HVAC: 1 kcal/h = 1.163 W.
Formula
ft·lbf/s = kcal/h × 0.8577847796095
or ft·lbf/s = kcal/h ÷ 1.165793592718
Derivation from SI units:
- 1 kcal_IT/h = 4186.8 J ÷ 3600 s = 1.163 W (exact)
- 1 ft·lbf/s = 1.3558179483314 W
- 1 kcal/h = 1.163 W ÷ 1.355817948331 W per ft·lbf/s = 0.8577847796095 ft·lbf/s
Both units are defined exactly, so the factor is exact. Kilocalorie per Hour definition: kilocalorie per hour; Foot-pound per Second definition: foot-pound per second.
Worked examples
- A reading of 1000 kcal/h converts to 857.7847796 ft·lbf/s.
1000 kcal/h × 0.8577847796 = 857.7847796 ft·lbf/s - A value of 10000 kcal/h is 8577.847796 ft·lbf/s.
10000 kcal/h × 0.8577847796 = 8577.847796 ft·lbf/s
