How the conversion works
Multiply by 3,600 to go from kilowatt-hour 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 kilowatt-hour — 1 kJ = 0.0002777777778 kWh.
