Common questions
- How many kilocalories are in one electronvolt?
- One electronvolt equals 3.829 × 10^-23 kilocalories. kcal = eV × 3.829294058 × 10^-23.
- How do you convert electronvolts to kilocalories?
- Use kcal = eV × 3.829294058 × 10^-23. So 10 eV is 3.829 × 10^-22 kcal.
- How many electronvolts are in one kilocalorie?
- One kilocalorie equals 2.6114474 × 10^22 electronvolts, which is the reverse of the conversion above.
- Is there more than one kind of kilocalorie?
- The "calorie" on food labels.
