How to Convert Calories to Electronvolts
To convert calories to electronvolts (eV), multiply the number of calories by 2.611 x 1019. This is because 1 calorie is equal to 4.184 joules, and 1 joule is equal to approximately 6.242 x 1018 eV.
Formula
Electronvolts = Calories × (2.611 × 1019)
or
eV = cal × 2.611e19
Step-by-step process
- Take the measurement in calories
- Multiply that number by 2.611e19
- The result is the equivalent energy in electronvolts
Examples
- 1 cal = 1 × 2.611e19 = 2.611 x 1019 eV
- 5 cal = 5 × 2.611e19 = 1.3055 x 1020 eV
- 10 cal = 10 × 2.611e19 = 2.611 x 1020 eV
