What if 22oz of beer (volume) WEIGHED 24oz (mass)?
According to the website below, searching for "beer", 22 oz weighs 23.281 oz. So it's close!

Wouldn't this mean that beer would need to be 8% more dense than water for this to work out? Quickly searching online, it seems like beer is more like 1% more dense than water, depending on the type of beer, so not sure this is possible.
Wait, I thought ounces were weight but liquid ounces were volume, making this irrelevant?
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.)
The US customary units are officially defined on top of metric, and 1 fl oz is 29.5735295625 mL, but an oz is 28.349523125 g. I imagine this decision was just to fuck with people (since 1ml of water weighs 1g at sea level, at 4°)
As a Brit, I find a lot of American units confusing but that makes my head hurt more than usual.
