Electronvolts to Calories Converter

1 electronvolt (eV) equals 3.8292941 × 10-20 calories (cal).

Quick answer

  • 1 electronvolt = 3.8292941 × 10-20 calories
  • 1 calorie = 2.6114474 × 1019 electronvolts
  • Formula: cal = eV ÷ 2.6114474 × 1019

1 electronvolt = 3.8292941 × 10-20 calories

How to convert electronvolts to calories

cal = eV ÷ 2.6114474 × 1019

To convert electronvolts to calories, divide the number of electronvolts by 2.6114474 × 1019.

Example: 18 eV to cal

  1. Start with the value in electronvolts: 18 eV.
  2. Divide by 2.6114474 × 1019: 18 ÷ 2.6114474 × 1019 = 6.8927293 × 10-19.
  3. Result: 18 electronvolts = 6.8927293 × 10-19 calories.

Going the other way, 1 calorie = 2.6114474 × 1019 electronvolts, so to convert calories back to electronvolts you multiply by the same number. See calories to electronvolts.
