Convert Megajoules (MJ) to Kilowatt-Hours (kWh)
Convert megajoules (MJ) to kilowatt-hours (kWh): divide by 3.6, since 1 kWh = 3.6 MJ. Bridges the joule-based SI energy unit and the kWh used on electricity bills.
Formula
1 MJ = 0.277778 kWh
To convert MJ to kWh, divide the value by 3.6.

About MJ to kWh
One kilowatt-hour is exactly 3.6 megajoules (1 kW for one hour is 3,600,000 J), so MJ divided by 3.6 gives kWh — 18 MJ = 5 kWh.
Megajoules show up in food energy, gas usage and physics, while kWh is the everyday unit for electricity. Converting MJ to kWh lets you compare a gas appliance's MJ rating against electricity priced per kWh.
