1 Erg = 7.3756e-8 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 = ergs × 0.0135582The erg (CGS) and foot-pound (imperial) are both small mechanical energy units — 1 erg = 10⁻⁷ J and 1 ft·lbf = 1.356 J, giving the conversion factor of 0.01356. Labs that work across unit systems need this conversion when referencing older literature or comparing equipment specs.
