About kilocalories and electronvolts
Kilocalorie (kcal)
A kilocalorie (kcal) is 1,000 calories, or 4,184 joules. It is the "Calorie" used on food labels and in diet and fitness tracking.
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.
kcal to eV: common questions
