American legal cup ? metric cup ? Canadian cup ? or one of the other ones.

Even if you narrow it to just the roughly the US you still have 4 + metric , so 5 different options.

and that doesn't even account for people just using the cup they have to hand.

It's not a rant at you, it's frustration with non-specific, arbitrary units.

Cups are 236.6 ml. 8 fluid ounces.

But, wow apparently the FDA rounds cups in nutrition labeling to be exactly 240ml “legal cup”, which I agree is super annoying. It’s 1.4% more.

“For purposes of nutrition labeling, 1 cup means 240 mL, 1 tablespoon means 15 mL, 1 teaspoon means 5 mL, 1 fluid ounce means 30 mL, and 1 ounce means 28 g (21 CFR 101.9(b)(5)(viii))”

WAIT.

US cups and metric cups are different?

Technically yes and that confusion is exactly my point.
