Measuring liquid with mass units? Toddlerific

    It seems to be an American thing. When I was in the US I was confused by all that drink cans are labeled in weight measurements rather than in liquid measurements. Although I guess it's the US so I should just be grateful that it wasn't been measured in fractions of a corgi or something.

    8 fluid ounces is a cup, 4 cups is a quart, 4 quarts is a gallon. Most canned drinks are 12 fl. oz, or 3/4 of a pint.

    8 ounces is half a pound.

    It makes perfect sense!

    Does that not mean that you get different amounts of liquid for the same 12 fluid ounces, because a pint of water does not weigh the same as a pint of beer, which in turn does not weigh the same as a paint of Coke.

    No. Fluid ounce is the volume. Most filling processes utilize the specific gravity of the solution and then fill by weight.

    1 L of water is 1kg. Let's say you add 500 grams of sugar. Now the solution has a specific gravity of 1.5mg per ml. So a 500 mL fill (16.9 oz) is 750mg. This is really rudimentary but I hope it kind of explains how the process should go.

    Why tho? 1kg=1l, 1g=1ml anyway, and I like to know how much something will weight in my backpack

    That's only for pure H20 (distilled water). Most drinking water has low amounts of mineral salts and other stuff.
