Full precision:2e-8 GW
Step-by-Step Solution
To convert 20 watts to gigawatts, we divide by 1000000000 because one gigawatt equals exactly 1000000000 watts.
1 gigawatt = 1000000000 watts
Since there are 1000000000 watts in every gigawatt, we divide our value by this factor:
20 ÷ 1000000000 = 2e-8 gigawatts
So 20 watts = 2e-8 gigawatts.
Quick check: 2e-8 × 1000000000 = 20 watts
