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
therms = ergs × 9.4804×10⁻¹⁰The erg is the CGS (centimeter-gram-second) unit of energy, widely used in geophysics and atmospheric science. The therm is the US natural gas unit — 100,000 BTU. Converting between them: 1 erg = 9.48×10⁻¹⁰ therms, or conversely 1 therm = 1.055×10¹⁰ ergs. This comes up in energy budget calculations spanning both unit systems.
