1 Foot-Pound Force = 0.0003 Kilocalorie
Key Formulas
Kilocalorie → Kilojoule
kJ = kcal × 4.184Kilojoule → Kilocalorie
kcal = kJ × 0.239006Kilowatt-Hour → Joule
J = kWh × 3600000Joule → Kilowatt-Hour
kWh = J × 2.77778e-7Formula
kcal = ft·lbf × 0.000324One foot-pound force equals 0.000324 kilocalories. Since 1 ft·lbf = 1.356 J and 1 kcal = 4184 J, the conversion is 1.356/4184 = 0.000324 kcal per ft·lbf. This connects mechanical work to dietary energy.
