Gigawatt-hour to megawatt-hour Conversion
1 gigawatt-hour (GW⋅hr) is equal to 1000 megawatt-hour (MW⋅hr).
1 GW⋅hr = 1000 MW⋅hr
or
1 MW⋅hr = 0.001 GW⋅hr
Formula
To convert a energy from gigawatt-hour (GW⋅hr) to megawatt-hour (MW⋅hr), multiply the energy in gigawatt-hour by 1000
e(MW⋅hr) = e(GW⋅hr) × 1000
Examples:
Convert 10 gigawatt-hour to megawatt-hour:
e(MW⋅hr) = 10GW⋅hr × 1000 = 10000 MW⋅hr

Frequently asked questions
How do I convert gigawatt-hour to megawatt-hour?
Multiply the value in gigawatt-hour by 1000 to get the result in megawatt-hour. For example, 5 GW⋅hr × 1000 = 5000 MW⋅hr.
How many megawatt-hour are in 1 gigawatt-hour?
1 gigawatt-hour (GW⋅hr) is equal to 1000 megawatt-hour (MW⋅hr).
How do I convert megawatt-hour back to gigawatt-hour?
Use the inverse operation: divide the value in megawatt-hour by 1000 to get the result in gigawatt-hour.
How accurate is the gigawatt-hour to megawatt-hour conversion?
The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
