The US also doesn’t label alcohol content effectively - % alone is not helpful.
In Australia for example, all booze containers tell you how many “standard drinks” they contain. 1 standard drink is the average amount of alcohol a body can process in an hour. If you have no more than 1-2 standard drinks in you, you should still pass a breathalyzer, depending on weight/gender.
A ~5% beer can is ~1.5 standard drinks. So if you drank 4x beers over the last 3 hours, best spend another hour drinking water before you drive:
4 beers x 1.5 = 6 standard drinks. - 3 hours = 3 standard drinks
Even what is called “1 standard drink” isn’t standardised across countries though.
For you, and also us in NZ it’s 10g of ethanol (approximately 12ml), in the UK it’s 8g. The US does in fact have a standard measure too, but 14g (and I don’t know enough to know how widely it’s actually used).
So as well as the standard drinks per bottle, the rule-of-thumb has to differ between countries too.
