The metric system uses a similar principle. 1 liter is a kg of water. It’s just named better.
Comment on Why do Americans measure everything in cups?

I’m always confused by their insistence to use fluid ounces.
An ounce is fine it’s a measurement to wait. But how can you measure liquids by weight when really what you mean is displacement.its like saying fluid kilograms, it’s not a thing, it makes no sense.
I know Americans probably know what it means but everybody else doesn’t have a clue. If you have 250 fluid oz of something is that like a bucket or a single droplet? Or is it a small booting lake, I have no idea at all.

Fl. Oz are actually nothing to do with weight. They are volume.
For each fluid oz. use 30 ml
It’s only approximate but the official measurements for nutrition actually do it in the US so it’s not a real unit anyway anymore.

Well yes, but also no. It is a unit of volume, but it comes from the volume that an ounce of fluid (specifically water) uses. Not at all unlike a gram being based on a cubic centimeter of water, which we also call a milliliter. Imperial just makes that a little more transparent, which also makes things a little more confusing.
