Wh to gwh Conversion Formula:
One Watt-hour is equal to 1e-9 Gigawatt-hour.
Formula: 1 Wh = 1e-9 GWh
By using this conversion factor, you can easily convert any energy from watt-hour to gigawatt-hour with precision.
How to Convert Wh to GWh?
Converting from Wh to GWh is a straightforward process. Follow these steps to ensure accurate conversions from watt-hour to gigawatt-hour:
- Select the Watt-hour Value: Start by determining the watt-hour (Wh) value you want to convert into gigawatt-hour (GWh). This is your starting point.
- Multiply by the Conversion Factor: To convert watt-hour to gigawatt-hour, multiply the selected Wh value by 1e-9. This factor is essential for accurately converting from a larger unit (Wh) to a much smaller unit (GWh).
- Illustration of Multiplication:
- 1 Wh = 1e-9 GWh
- 10 Wh = 0.000000010 GWh
- 100 Wh = 0.000000100 GWh
- Find the Conversion Result: The result of this multiplication is your converted value in gigawatt-hour unit. This represents the same energy but in a different unit.
- Save Your Gigawatt-hour Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in gigawatt-hours.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the watt-hour value by 1e+9. This alternative method also gives you the correct energy in gigawatt-hours.
- Illustration of Division:
- GWh = wh ÷ 1e+9

Watt-hour to Gigawatt-hour Examples
Example 1:
Convert 0.9 Watt-hour to Gigawatt-hour.
Solution:
We know that one Watt-hour is equivalent to 1e-9 Gigawatt-hour.
Therefore,
0.9 Wh = 0.9 x 1e-9 GWh.
0.9 Wh = 9e-10 GWh.
Hence, 0.9 Watt-hour is approximately equal to 9e-10 Gigawatt-hour.
Example 2:
Convert 5 Watt-hour to Gigawatt-hour.
Solution:
We know that one Watt-hour is equivalent to 1e-9 Gigawatt-hour.
Therefore,
5 Wh = 5 x 1e-9 GWh.
5 Wh = 0.000000005 GWh.
Hence, 5 Watt-hour is approximately equal to 0.000000005 Gigawatt-hour.
Example 3:
Convert 79 Watt-hour to Gigawatt-hour.
Solution:
We know that one Watt-hour is equivalent to 1e-9 Gigawatt-hour.
