How fluid ounces in a cup?

Answer 1

Any old cups that you drink coffee or cocoa out of can have different sizes, anything from

a demi-tasse to a flagon or a shtein that you need both hands and a helper to lift.

But the official standard "cup" ... kept secure in a clean dish-cloth in the back of a cabinet

in Funk & Wagnall's pantry ... is equivalent to a capacity of 8 fluid ounces.

Answer 2

1 cup = 8 ounces

1 ounce = 0.12 cup

Answer 3

There are 8 fluid ounces in a cup.
