How to Convert Megajoules to Megawatt-hours

Convert megajoules to megawatt-hours with this simple formula:

megawatt-hours = megajoules × 0.000278

Converting a megajoule energy measurement to a megawatt-hour measurement involves multiplying the energy by the conversion ratio to find the result. One megajoule is equal to 0.000278 megawatt-hours, so to convert simply multiply by 0.000278.

For example, here's how to convert 5 megajoules to megawatt-hours using the formula above.

5 MJ = (5 × 0.000278) = 0.001389 MWh
