Comment on Why do Americans measure everything in cups?

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.
