How the conversion works
Multiply by 0.2390057361 to go from kilojoule 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 kilojoule — 1 kcal = 4.184 kJ.
