About electronvolts and calories
Electronvolt (eV)
An electronvolt (eV) is about 1.602 × 10⁻¹⁹ joules, the energy an electron gains across one volt. It is used in atomic and particle physics.
Calorie (cal)
A calorie (cal) here is the thermochemical calorie, exactly 4.184 joules. Food "Calories" are kilocalories, a thousand times larger.
