kcal = kJ × 0.239006Kilowatt-Hour → Joule
J = kWh × 3600000Joule → Kilowatt-Hour
kWh = J × 2.77778e-7Formula
ft·lbf = eV × 8.4623×10⁻¹⁸An electronvolt (eV) is the energy acquired by an electron accelerating through one volt potential — about 1.602×10⁻¹⁹ joules. A foot-pound is the mechanical work done by one pound-force over one foot — about 1.356 joules. The ratio of roughly 8.46×10⁻¹⁸ reflects the enormous scale difference between quantum and macroscopic mechanical energy.
