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
eV = ft·lbf × 5.9612×10¹⁸The foot-pound is an imperial mechanical energy unit; the electronvolt is a quantum unit. One ft·lbf = 1.356 J while one eV = 1.602×10⁻¹⁹ J, giving approximately 5.96×10¹⁸ eV per ft·lbf. Particle physicists and quantum engineers use this when bridging macroscopic mechanical work to quantum energy levels.
