One cup is equal to 8 ounces, so 16 ounces is equal to 2 cups. Sixteen ounces, or 2 cups, is also equivalent to 1 pint.
In the United States, although cups, pints and quarts are universal measurements that are used in reference to both dry and wet ingredients, ounces are a volume measurement for liquid. The same is true for gallons. Equally, in the United States, dry ingredients are measured as either milliliters or liters. British measurements, however, do no make the same distinction. The metric system is primarily only used in the United States in reference to cooking and measuring food items.
