A pound is a weight, so the number of cups in one depends on what you are weighing. A pound of butter is 2 cups because a 1 lb box holds four 1/2-cup sticks, but a pound of all-purpose flour is about 3.8 cups and a pound of granulated sugar about 2.3 cups. The cups in a pound chart covers 18 ingredients.
