How the conversion works
Multiply by 3.829294058e-23 to go from electron volt to kilocalorie, or divide by it to go back. Every conversion on this site routes through the SI value (J) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? kilocalorie to electron volt — 1 kcal = 2.611447397e+22 eV.
