    But most actual cups are 200ml, whereas a pint is 470ml. So if you use a real cup as a measuring tool you are short on the pint.

          I’m also confused by this 473 ml pint, is that some American thing? I always thought pints were 568 ml… as in pint of beer.

            Imperial (used in the British Empire) vs US customary. The imperial fluid gallon (4.54609 L exactly) was never historically defined in terms of another unit while the US fluid gallon was defined as 231 cubic inches (3.785411784 L exactly). A pint is defined as 1/16 of a gallon in each system, but they can’t agree on how many ounces are in a pint (16 for US, 20 for imperial). Note that there are also imperial and US customary dry gallons and thus imperial and US customary dry pints…

              That adds a hilarious new dimension to how shitty the Imperial system is because I had no idea that different countries would just define their own versions of the measurements.
