Watt-hour to gigawatt-hour converter (wh to gwh)

Conversion Formula

1 wh = 1.00e-9 gwh

Step-by-Step Explanation

1. Understand the base relationship:
   1 Watt-hour = 3.60k joules
   1 Gigawatt-hour = 3.60T joules
2. Establish the conversion factor:
   1 wh = (3.60k J) / (3.60T J/gwh) = 1.00e-9 gwh
3. Apply the conversion:
   Multiply the value in wh by 1.00e-9 to get the equivalent in gwh

Example Conversion

Convert 5 wh to gwh:

5 wh × 1.00e-9 = 5.00e-9 gwh
