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?
