how many oz in a cup

A cup is a unit of measurement used to measure volume. One cup is equal to 8 fluid ounces, or about 237 milliliters. This is the same as 1/2 pint or 16 tablespoons. In the United States, the customary system of measurement is used, which is why a cup is equal to 8 fluid ounces.

In the metric system of measurement, one cup is equal to 250 milliliters. This is the same as 8.45 fluid ounces. In the UK, the imperial system of measurement is used, which is why one cup is equal to 10 fluid ounces.

It is important to note that when measuring liquids, a cup should not be confused with a glass. A glass is a unit of volume used to measure dry goods, such as sugar, flour, and oats. One glass is equal to 4 fluid ounces, or about 118 milliliters.
