How many cups are in a pound of sugar?
For granulated sugar, 1 pound is about 2¼ cups. But powdered and brown sugar fill a cup differently—use the right row below before you bake.
Approximate conversion. Cup measures vary with sugar type and how it is filled.

Cups in a 1, 2, 3, or 4 lb bag of sugar
The most useful kitchen conversion depends on the sugar in your recipe. These figures are practical approximations for standard US measuring cups.
| Bag weight | Granulated sugar | Powdered / icing sugar | Brown sugar, packed |
|---|---|---|---|
| 1 lb | 2¼ cups | 3⅝ cups | 2¼ cups |
| 2 lb | 4½ cups | 7¼ cups | 4½ cups |
| 3 lb | 6¾ cups | 10⅞ cups | 6¾ cups |
| 4 lb | 9 cups | 14½ cups | 9 cups |

Three small details that change the cup count
Granulated sugar: scoop and level
Fill the cup without shaking it down, then sweep a straight edge across the top. Settling the sugar can add more than your recipe expects.
Icing sugar: sift only when the recipe says so
Sifting adds extra air. If a recipe calls for “1 cup sifted,” sift first and then measure. If it says “1 cup powdered sugar, sifted,” measure first.
Brown sugar: pack it firmly
Press brown sugar into the cup until it holds its shape when turned out. This is the standard assumption behind brown sugar cup measurements.
Real-kitchen examples
When a bag is easier than a scale
Making cookies with a 4 lb bag?
A 4 lb bag of granulated sugar gives you about 9 cups—enough for several batches of cookies, cakes, or pantry baking.
Frosting calls for one pound of icing sugar?
Plan on roughly 3⅝ cups of powdered sugar. For buttercream, weighing the sugar is the easiest way to keep the texture consistent.
Practical measurement note
Cups are convenient. A scale is more exact.
This guide uses common home-kitchen cup weights to give fast, reliable estimates. For delicate cakes, macarons, candy, and large-batch baking, follow the recipe’s gram weight whenever it is available.
