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 = eV × 1.5198×10⁻¹⁸The electronvolt is a quantum-scale unit — the energy gained by one electron through one volt. A therm is 100,000 BTU of macroscopic heat energy. The ratio reflects a 10¹⁸ scale difference per particle. Particle physicists and radiation chemists convert eV to therms when scaling quantum process energies up to bulk material effects.
