if weighted average is too small

I have a metric in % and another column with the Number of accounts for each row. I created a weighted average using rhe 5 metric and the number of accunts as the weights. My answer however, is very very samll (due to the large populated rows having small or a 0% in the % metric). No my queston is, when the weighted average is so small, something like this 0.0000674% .. how do I interpret this, or is there anything I need to do to show this differently.

I am actually comparing 2 separate groups, using the same number of accounts, but different % metrics, and comparing the final weighted averages between the 2.
