How the conversion works

Multiply by 1,000 to go from megajoule to kilojoule, 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? kilojoule to megajoule — 1 kJ = 0.001 MJ.
