Kilocalories to Electronvolts Converter
1 kilocalorie (kcal) equals 2.6114474 × 1022 electronvolts (eV).
Quick answer
- 1 kilocalorie = 2.6114474 × 1022 electronvolts
- 1 electronvolt = 3.8292941 × 10-23 kilocalories
- Formula: eV = kcal × 2.6114474 × 1022
1 kilocalorie = 2.6114474 × 1022 electronvolts
How to convert kilocalories to electronvolts
eV = kcal × 2.6114474 × 1022
To convert kilocalories to electronvolts, multiply the number of kilocalories by 2.6114474 × 1022.
Example: 18 kcal to eV
- Start with the value in kilocalories: 18 kcal.
- Multiply by 2.6114474 × 1022: 18 × 2.6114474 × 1022 = 4.7006053 × 1023.
- Result: 18 kilocalories = 4.7006053 × 1023 electronvolts.
Going the other way, 1 electronvolt = 3.8292941 × 10-23 kilocalories, so to convert electronvolts back to kilocalories you divide by the same number. See electronvolts to kilocalories.
