About kilojoules and electronvolts
Kilojoule (kJ)
A kilojoule (kJ) is 1,000 joules. Food energy on nutrition labels is often shown in kJ as well as kcal.
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.
kJ to eV: common questions
