1 fl oz (volume) of water weighs about 1 oz (weight). It varies depending on a bunch of stuff, ya know, cause imperial sucks, but I believe the standard rate is 1 fl oz weighs about 1.043 oz. So assuming beer has similar density as water, 22 fl oz would weigh somewhere around 23 oz.
(Some Google searches show that some definitions of fl oz has it as 1 fl oz = 30 ml exactly, but I'm starting to confuse myself and you know how infuriating imperial is.)
I've said this before, but Factorio is genuinely the only thing that has made me lose track of time before. When I'm goofing off into the wee hours of the night, normally I have a vague sense of time passing. I won't know what time it is, but I'll know that it's late and I should probably stop whatever it is I'm doing (and won't). And then I'll look at the clock and it's 2am-- late, but not surprising.
But then came Factorio. This was when I first started playing, around the time I just started making black science packs. I was refitting my bases to work with laser turrets, and making minor modifications here and there like upgrading from 2 saturated belts of iron to 4 and such. Nothing major. I'd just do these things, maybe an hour or two, and head to bed. So you can imagine my surprise when I look at the clock and it was 5:30 AM. I was baffled; I had no idea I'd spent that long modifying my base. Like 7 hours straight, no breaks. And then the exhaustion hit, and I saved and went immediately to bed.
Cracktorio man, the addiction is real.
