How the conversion works

Multiply by 0.2777777778 to go from megajoule to kilowatt-hour, 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? kilowatt-hour to megajoule — 1 kWh = 3.6 MJ.
