Now, you might be thinking, "Wait, isn't a pint just a pint?" Not quite, my friend! In the United States, a pint is usually 16 ounces, which is around 473 milliliters. But in the United Kingdom and Ireland, a pint is indeed 568 milliliters - that's about 20% more booze!
This difference might seem small, but it can add up (or should I say, pour up?) over the course of a night out. Just imagine ordering a pint in the US and then traveling to the UK and being like, "Wait, this pint is way bigger!" Yeah, you might want to pace yourself!
