Ergs to Kilowatt-Hours (kWh) Converter
Enter a value to instantly convert between energy units.
1 Erg = 2.7778e-14 Kilowatt-Hour
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
kWh = ergs × 2.7778×10⁻¹¹The erg (CGS unit, 10⁻⁷ J) and kilowatt-hour (SI-derived electrical unit, 3.6 MJ) differ by 10 orders of magnitude. Converting 1 erg gives 2.78×10⁻¹¹ kWh. Labs working with geophysical data, atmospheric energy budgets, or legacy CGS literature need this conversion to express energy in practical electrical terms.
