Megajoule to gigawatt-hour Conversion
1 megajoule (MJ) is equal to 0.0000002777777778 gigawatt-hour (GW⋅hr).
1 MJ = 0.0000002777777778 GW⋅hr
or
1 GW⋅hr = 3600000 MJ
Formula
To convert a energy from megajoule (MJ) to gigawatt-hour (GW⋅hr), divide the energy in megajoule by 3600000
e(GW⋅hr) = e(MJ) / 3600000
Examples:
Convert 1000 megajoule to gigawatt-hour:
e(GW⋅hr) = 1000MJ / 3600000 = 0.0002777777778 GW⋅hr

Frequently asked questions
How do I convert megajoule to gigawatt-hour?
Divide the value in megajoule by 3600000 to get the result in gigawatt-hour. For example, 5 MJ ÷ 3600000 = 1.388889e-6 GW⋅hr.
How many gigawatt-hour are in 1 megajoule?
1 megajoule (MJ) is equal to 2.77778e-7 gigawatt-hour (GW⋅hr).
How do I convert gigawatt-hour back to megajoule?
Use the inverse operation: multiply the value in gigawatt-hour by 3600000 to get the result in megajoule.
How accurate is the megajoule to gigawatt-hour conversion?
The converter multiplies by the conversion factor 3600000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
