How to convert kilocalories to electronvolts
One kilocalorie equals 2.611447 × 10²² electronvolts, so multiply the number of kilocalories by 2.611447 × 10²².
eV = kcal × 2.611447 × 10²²
1 kcal = 2.611447 × 10²² eV · 1 eV = 3.829294 × 10⁻²³ kcal
Worked example
To convert 5 kilocalories to electronvolts: 5 kcal × 2.611447 × 10²² = 1.305724 × 10²³ eV.
