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 = BTU × 1.0551×10¹⁰The BTU is a practical heat unit; the erg is a CGS physics unit. Converting between them: 1 BTU = 1055 J = 1.055×10¹⁰ ergs. Labs working with older literature, atmospheric models, or geophysical data frequently encounter energy in ergs and need to relate it to BTU.
