Megawatt-hour to joules Conversion
1 megawatt-hour (MW⋅hr) is equal to 3600000000 joules (joule).
1 MW⋅hr = 3600000000 joule
or
1 joule = 0.0000000002777777778 MW⋅hr
Formula
To convert a energy from megawatt-hour (MW⋅hr) to joules (joule), multiply the energy in megawatt-hour by 3600000000
e(joule) = e(MW⋅hr) × 3600000000
Examples:
Convert 1 megawatt-hour to joules:
e(joule) = 1MW⋅hr × 3600000000 = 3600000000 joule

Frequently asked questions
How do I convert megawatt-hour to joules?
Multiply the value in megawatt-hour by 3600000000 to get the result in joules. For example, 5 MW⋅hr × 3600000000 = 1.8e10 joule.
How many joules are in 1 megawatt-hour?
1 megawatt-hour (MW⋅hr) is equal to 3.6e9 joules (joule).
How do I convert joules back to megawatt-hour?
Use the inverse operation: divide the value in joules by 3600000000 to get the result in megawatt-hour.
How accurate is the megawatt-hour to joules conversion?
The converter multiplies by the conversion factor 3600000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
