Gigajoule to megawatt-hour Conversion
1 gigajoule (GJ) is equal to 0.2777777778 megawatt-hour (MW⋅hr).
1 GJ = 0.2777777778 MW⋅hr
or
1 MW⋅hr = 3.6 GJ
Formula
To convert a energy from gigajoule (GJ) to megawatt-hour (MW⋅hr), divide the energy in gigajoule by 3.6
e(MW⋅hr) = e(GJ) / 3.6
Examples:
Convert 1000 gigajoule to megawatt-hour:
e(MW⋅hr) = 1000GJ / 3.6 = 277.7777778 MW⋅hr
