How to convert Electron Volts to Calories
Multiply the electron volts value by 3.8293e-20: 1 eV = 3.8293e-20 cal. Going the other way, 1 cal = 2.6114e+19 eV, so divide by 3.8293e-20 or use the Calories to Electron Volts converter.
About these units
Electron Volts (eV)
An electronvolt is the energy an electron gains when accelerated through one volt, exactly 1.602176634 × 10⁻¹⁹ joules. Particle and photon energies are quoted in eV.
Calories (cal)
The calorie used here is the thermochemical calorie, exactly 4.184 joules, roughly the energy needed to warm one gram of water by one degree Celsius. Food calories are actually kilocalories.
