1 Kilowatt-Hour = 3.6000e+13 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
ergs = kWh × 3.6×10¹³The erg is the CGS (centimeter-gram-second) unit of energy — about the work done by a mosquito landing on your arm. A kilowatt-hour is 3.6 MJ, which is 36 trillion ergs. Physics labs working with CGS systems, especially older publications or atmospheric science, still commonly express energy in ergs.
