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))”
