1 Kilocalorie = 4.1840e+10 Erg
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
erg = kcal × 41840000000One kilocalorie equals 41.84 billion ergs. Since 1 kcal = 4184 J and 1 erg = 10⁻⁷ J, the conversion is simply 4184/10⁻⁷ = 41.84×10⁹ erg. This conversion appears in older physics texts, astrophysics, and CGS system calculations.
