How many ounces in a cup?

quart, gallon, and so on. So I'm going to write them down here, secure in the knowledge that I can always search my own damned web site next time I need them.

3 teaspoons is 1 tablespoon
8 ounces is 1 cup
16 ounces is 2 cups which is 1 pint
32 ounces is 4 cups which is 2 pints which is 1 quart
128 ounces is 16 cups which is 8 pints which is 4 quarts which is 1 gallon
