About 2 1/2 cups of brown sugar make up one pound. Depending on how tightly packed the brown sugar is while measuring, the actual number of cups will vary.
Users can receive about 3 to 3 1/2 cups of brown sugar for every pound of sugar if it is not tightly packed. The majority of recipes requiring brown sugar call for it to be tightly packed. One pound of granulated sugar equals around 2 1/4 cups, while one pound of powdered sugar is roughly 3 3/4 cups. The amount of cups per pound of powdered sugar will increase if it is sifted.
