Use the converter below to change any calories value into electronvolts instantly — with formula, conversion table, and real-world examples.
Example: 10 cal × 2.6114e19 = 2.6114e20 eV.
The gram calorie (small calorie) equals 4.184 joules — the energy to raise 1 g of water by 1 °C. It is a scientific unit, distinct from the nutrition "Calorie" (kcal). Largely replaced by joules in modern science.
The electronvolt equals 1.602 × 10⁻¹⁹ joules — the energy gained by an electron accelerated through 1 volt. It is the natural energy unit of atomic, nuclear and particle physics. Chemical bonds are a few eV; LHC protons reach 7 TeV = 7 × 10¹² eV.
