Calories to Electronvolts Converter
1 calorie (cal) equals 2.6114474 × 1019 electronvolts (eV).
Quick answer
- 1 calorie = 2.6114474 × 1019 electronvolts
- 1 electronvolt = 3.8292941 × 10-20 calories
- Formula: eV = cal × 2.6114474 × 1019
1 calorie = 2.6114474 × 1019 electronvolts
How to convert calories to electronvolts
eV = cal × 2.6114474 × 1019
To convert calories to electronvolts, multiply the number of calories by 2.6114474 × 1019.
Example: 18 cal to eV
- Start with the value in calories: 18 cal.
- Multiply by 2.6114474 × 1019: 18 × 2.6114474 × 1019 = 4.7006053 × 1020.
- Result: 18 calories = 4.7006053 × 1020 electronvolts.
Going the other way, 1 electronvolt = 3.8292941 × 10-20 calories, so to convert electronvolts back to calories you divide by the same number. See electronvolts to calories.
