The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Character Counts

This extension is fairly simple, straight-forward, and self-explanatory (if not, please let me know what I can do to enhance it). In version 2 you can now change what format the source string is in (i.e., the string to be converted, in the top input box). Source options are the same as the conversion output options; ASCII(char), ASCII(int), and Binary. The 'Convert' link will then cycle through the 3 conversions. Character Counts is open-sourced on GitHub (feel free to make a PR for adding something useful). * GitHub: https://github.com/KDCinfo/character-counts The latest update upgraded the Chrome extension manifest from v2 to v3.
