12 megajoules in kilowatt-hour

12 megajoules equals 3.333333 kilowatt-hour 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 megajoule = 0.277778 kilowatt-hour, so this amount is 3.333333 kilowatt-hour. Reverse: 1 kilowatt-hour ≈ 3.6 megajoule. Note that 1 kWh is exactly 3.6 MJ.
