Electronvolts to Kilocalories Converter

1 electronvolt (eV) equals 3.8292941 × 10-23 kilocalories (kcal).

Quick answer

  • 1 electronvolt = 3.8292941 × 10-23 kilocalories
  • 1 kilocalorie = 2.6114474 × 1022 electronvolts
  • Formula: kcal = eV ÷ 2.6114474 × 1022

1 electronvolt = 3.8292941 × 10-23 kilocalories

How to convert electronvolts to kilocalories

kcal = eV ÷ 2.6114474 × 1022

To convert electronvolts to kilocalories, divide the number of electronvolts by 2.6114474 × 1022.

Example: 18 eV to kcal

  1. Start with the value in electronvolts: 18 eV.
  2. Divide by 2.6114474 × 1022: 18 ÷ 2.6114474 × 1022 = 6.8927293 × 10-22.
  3. Result: 18 electronvolts = 6.8927293 × 10-22 kilocalories.

Going the other way, 1 kilocalorie = 2.6114474 × 1022 electronvolts, so to convert kilocalories back to electronvolts you multiply by the same number. See kilocalories to electronvolts.
