How the conversion works
Multiply by 239.0057361 to go from kilojoule to calorie, 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? calorie to kilojoule — 1 cal = 0.004184 kJ.
