Megajoule to megawatt-hour Conversion
1 megajoule (MJ) is equal to 0.0002777777778 megawatt-hour (MW⋅hr).
1 MJ = 0.0002777777778 MW⋅hr
or
1 MW⋅hr = 3600 MJ
Formula
To convert a energy from megajoule (MJ) to megawatt-hour (MW⋅hr), divide the energy in megajoule by 3600
e(MW⋅hr) = e(MJ) / 3600
Examples:
Convert 10 megajoule to megawatt-hour:
e(MW⋅hr) = 10MJ / 3600 = 0.002777777778 MW⋅hr

Frequently asked questions
How do I convert megajoule to megawatt-hour?
Divide the value in megajoule by 3600 to get the result in megawatt-hour. For example, 5 MJ ÷ 3600 = 0.001388889 MW⋅hr.
How many megawatt-hour are in 1 megajoule?
1 megajoule (MJ) is equal to 2.77778e-4 megawatt-hour (MW⋅hr).
How do I convert megawatt-hour back to megajoule?
Use the inverse operation: multiply the value in megawatt-hour by 3600 to get the result in megajoule.
How accurate is the megajoule to megawatt-hour conversion?
The converter multiplies by the conversion factor 3600 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
