I edited my comment with more fact checking, and the DMG mentions the 1 oz potions on page 139. That also has implications for the density of a potion–a piece of granite would float in it! Honestly I’m fine with being wrong about the volume of a potion, that’s a legit fun fact
As for your source, there are better options than a PDF from 3 years ago. Am I allowed to mention that easily googleable website that has tools that we can use for 5e on this forum?
Yeah, I tend to prefer on device resources when I can’t have physical copies. Online resources tend to be a pain in the ass when you need them most, so I never think of them.
I don’t play 5e, nor run a game with it, so I haven’t bothered to find newer copies of the PDF. If they’ve changed that much in a few years that the official site/books are no longer useful for quickly checking things, I can’t say I’ll ever bother to look for new files. It would mean that they’ve turned d&d into a churn based monetary thing rather than a reliable game system. I’m just not interested in that.
I mean, I have all the old ad&d books, most of the 3.X, and the box sets from before 2e. The 5e stuff, I’ll never buy any of if there’s not a good reason to.
