How many ounces are in 1 cup?

Answer 1

In the US, 1 cup = 8 fluid ounces (*not identical to the avoirdupois ounce which is weight)

In the US, one standard measuring cup contains 8 fluid ounces, but there is also a dry measure using the term cup, equal to 8 ounces.

The UK cup is equal to 10 Imperial ounces, which are equal to 0.96 US ounces, because they are based on the avoirdupois (weight) ounce.

This standard - as with standard spoon measurements - varies from country to country. As well, ordinary coffee cups can vary greatly in capacity, so standard measures depending on the country of origin of a recipe should always be used, rather than those mismatched cups no longer part of dinner sets, which sit in the kitchen cupboard.

Fluid ounces are an volume measurement which is not the same as the weight of an item. Volume measurements are how much of a container is filled which is totally different to how much an item weighs. A cup of chopped carrot will weigh more than a cup of chopped marshmallow.

In many cases some variation in quantities doesn't matter at all, but - especially in baking - the use of different size cups for measuring can invite disaster. So use standard measures, and check the country of origin of the recipe in case ther standard measures are different.
