1 Kilocalorie = 3085.96 Foot-Pound Force
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
ft·lbf = kcal × 3088.025One kilocalorie equals 3088.025 foot-pounds force. Since 1 kcal = 4184 J and 1 ft·lbf = 1.356 J, the conversion is 4184/1.356 = 3088 ft·lbf. This connects dietary energy to mechanical work — a 2000 kcal/day diet is equivalent to about 6.2 million ft·lbf/day.
