Measuring liquid with mass units? Toddlerific

[-] echodot@feddit.uk 7 points 23 hours ago* (last edited 23 hours ago)

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!

A pint's a pound, not quite the world around, mostly just in the US, Liberia, and Myanmar, but also in several commonwealth countries and not to a precision level where local gravity applies

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.

A fluid ounce is a unit of volume.

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

[-] Goodlucksil@lemmy.dbzer0.com 1 points 19 hours ago

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

[-] notSys@lemmy.cafe 4 points 18 hours ago

The difference is negligible for most drinks.

[-] Eheran@lemmy.world 1 points 18 hours ago

So? What is the density of drinking water then, that you specifically mention this when someone says water is ~1?

[-] Goodlucksil@lemmy.dbzer0.com 1 points 18 hours ago

I can't find it.
