80 watt-hours in joule

80 watt-hours equals 288000 joule 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 watt-hour = 3600 joule, so this amount is 288000 joule. Reverse: 1 joule ≈ 0.000278 watt-hour. Note that 1 kWh is exactly 3.6 MJ.
