Gigawatt-hour to watt-hour Conversion
1 gigawatt-hour (GW⋅hr) is equal to 1000000000 watt-hour (W⋅hr).
1 GW⋅hr = 1000000000 W⋅hr
or
1 W⋅hr = 0.000000001 GW⋅hr
Formula
To convert a energy from gigawatt-hour (GW⋅hr) to watt-hour (W⋅hr), multiply the energy in gigawatt-hour by 1000000000
e(W⋅hr) = e(GW⋅hr) × 1000000000
Examples:
Convert 1000 gigawatt-hour to watt-hour:
e(W⋅hr) = 1000GW⋅hr × 1000000000 = 1000000000000 W⋅hr

Frequently asked questions
How do I convert gigawatt-hour to watt-hour?
Multiply the value in gigawatt-hour by 1000000000 to get the result in watt-hour. For example, 5 GW⋅hr × 1000000000 = 5e9 W⋅hr.
How many watt-hour are in 1 gigawatt-hour?
1 gigawatt-hour (GW⋅hr) is equal to 1e9 watt-hour (W⋅hr).
How do I convert watt-hour back to gigawatt-hour?
Use the inverse operation: divide the value in watt-hour by 1000000000 to get the result in gigawatt-hour.
How accurate is the gigawatt-hour to watt-hour conversion?
The converter multiplies by the conversion factor 1000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
