1 kilowatt-hour in kilojoule

1 kilowatt-hour equals 3600 kilojoule as a pure energy equivalence on NiftyRecipe.

Kilowatt-hours measure delivered electrical energy. Expressing them as kcal, kJ, MJ or BTU is physics only-not a forecast of what a household pays. The factor is 1 kilowatt-hour = 3600 kilojoule, so this amount is 3600 kilojoule. Reverse: 1 kilojoule ≈ 0.000278 kilowatt-hour. Note that 1 kWh is exactly 3.6 MJ.
