A little context on Kilocalorie and Electronvolt helps this conversion stick, along with some frequently asked questions below.
Step-by-step example — Convert 200 kcal to eV:
A Kilocalorie (kcal) equals 1,000 calories and is the actual unit behind the 'Calorie' shown on food nutrition labels.
An Electronvolt (eV) is an extremely small energy unit used for particle and atomic-scale physics.
The formula is: Electronvolt = Kilocalorie x 26114474000000000000000. Multiply any Kilocalorie value by 26114474000000000000000 to get the equivalent in Electronvolt.
1 kcal = 26114474000000000000000 eV.
1 eV = 0 kcal.
Kilocalorie is bigger than Electronvolt. 1 Kilocalorie = 26114474000000000000000 eV.
500 kcal = 1.305724e+25 eV.
1000000 eV = 3.829294e-17 kcal.
Nutrition labeling adopted the capitalized "Calorie" as shorthand for kilocalorie, so "200 Calories" on a label means 200 kcal, not 200 of the small chemistry calories.
