1 pound of brown sugar is equivalent to around 2 1/2 cups. The actual amount of cups depends on how tightly the brown sugar is packed upon measurement.
If the sugar is not compacted tightly, users can obtain approximately 3 to 3 1/2 cups of brown sugar per pound. Most brown sugar recipes require the sugar to be tightly packed. 1 pound of powdered sugar equals roughly 3 3/4 cups, while 1 pound of granulated sugar equals around 2 1/4 cups. There will be more cups per pound of powdered sugar if it is sifted.
