Potential knowledge is probably infinite. How much is a finite fraction of infinite? Likely not much.
To be fair, when we say "we know much" we don't compare with all that potential knowledge, but with the knowledge of the generations that preceded us, or compared to the uneducated goat herder on some steppe, or some such thing. But this is also tricky, because they knew/know thing that we don't and so we find ourselves in a muddy morass, even when guessing how much we know (compared to someone else), let alone trying to accurately assess this. Unless we are very specific of course, like narrowing it down to maths or nuclear science.
Come to think of it, that's probably what you meant.

OK, scratch this.
