    Here’s a handy guide to SE:

    1 liter = 10 deciliter

    1 deciliter = 10 centiliter

    1 centiliter = 10 milliliter

    I live in a country where these measurements aren’t used, so without any background knowledge I interpreted the comma as “and” at first. Looking at the picture, I’m pretty sure it’s meant to be “or” instead, in which case they should have used a slash instead of a comma imo.

    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.

        Currently used definitions of the cup:

        The US customary cup (236.6 mL) is 8 US customary fluid ounces. The US customary fluid ounce (29.6 mL) is 1/16 of a US fluid pint.

        The US legal cup (240 mL) is 8 US nutritional fluid ounces. The US nutritional fluid ounce is 30 mL.

        The metric cup is 250 mL

        Historically used definitions of the cup:

        Ths British cup (284.1 mL) is 10 imperial fluid ounces. The imperial fluid ounce (28.4 mL) is 1/20 of an imperial fluid pint

        The Canadian cup (227.3 mL) is 8 imperial fluid ounces

    There are 20 fl oz. to a pint

    Instead of cups you should use half pints.

    There are 8 pints to the gallon.

    Unless you specify which pint, gallon then you’re probably wrong anywhere outside the US. Even then you could have to deal with vintage Canadian equipment with imperial labeling.

    US Cups are random in measurement and only sometimes half a pint.

    The imperial fluid oz. has one value 28.413 ml

    The US fl. oz used to be 29.573 ml. But now can officially be 30 ml in some settings.

    Metric is the best system, followed by imperial which at least is still a consistent standard.

    Then US customary measures where the written value may or may not have to meet a standard these days.

    The US has been using metric for everything important for a long time now like the rest of the world. Except the Mars probe NASA crashed.

      Correction, NASA only uses metric. Lockheed Martin was contracted for some systems and that’s where the unit conversion problems came from.

      Still partially NASA’s fault for not checking / enforcing units.

    This is very confusing. I assumed at first that a gallon was 4 quarts + 8 pints + 16 cups, a weird way to write 8 quarts… Because a quart in my interpretation is 2 pints + 4 cups = 8 cups. I mean the diagram does show the gallon containing all of them.
