How the conversion works

Multiply by 239,005.7361 to go from megajoule 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 megajoule — 1 cal = 0.000004184 MJ.
