How to Convert Kilocalorie to Foot-pound
- 1 kcal = 3085.960033 ft·lbf
- 1 ft·lbf = 0.0003240482668 kcal
- Example: convert 15 kcal to ft·lbf: 15 kcal = 15 × 3085.960033 ft·lbf = 46289.40049 ft·lbf
Reference conditions. kcal: Thermochemical kilocalorie (food Calorie), 4184 J exactly.
Formula
ft·lbf = kcal × 3085.960032576
Derivation from SI units:
- 1 kcal = 1000 cal = 4184 J (exact)
- 1 ft·lbf = 0.3048 m × 4.4482216152605 N = 1.3558179483314 J
- 1 kcal = 4184 J ÷ 1.355817948331 J per ft·lbf = 3085.960032576 ft·lbf
Both units are defined exactly, so the factor is exact. Kilocalorie definition: kilocalorie; Foot-pound definition: foot-pound.
Worked examples
- A reading of 200 kcal converts to 617192.0065 ft·lbf.
200 kcal × 3085.960033 = 617192.0065 ft·lbf - A value of 1500 kcal is 4628940.049 ft·lbf.
1500 kcal × 3085.960033 = 4628940.049 ft·lbf
