How Many Pounds Are in a Cup of Sugar?

How many pounds are in 1 cup of each sugar type?

According to King Arthur Baking's ingredient weight chart, different sugars weigh different amounts per US cup. Granulated white sugar weighs 0.44 lb per cup (7 oz, 200 g). Brown sugar (packed) weighs 0.47 lb per cup (7.5 oz, 213 g). Powdered sugar weighs 0.25 lb per cup (4 oz, 113 g). Coconut sugar weighs 0.32 lb per cup (5.1 oz, 145 g). Turbinado sugar weighs 0.42 lb per cup (6.7 oz, 191 g). Demerara sugar weighs 0.42 lb per cup (6.8 oz, 192 g). Date sugar weighs 0.22 lb per cup (3.5 oz, 100 g). Maple sugar weighs 0.41 lb per cup (6.5 oz, 184 g). The variation comes from crystal size and packing density: powdered sugar is the lightest because its fine particles trap more air, while brown sugar is the heaviest because packing compresses the molasses-coated crystals together.

How many cups are in 1 pound of sugar?

1 pound of granulated sugar yields about 2.25 cups (16 oz divided by 7 oz per cup). 1 pound of brown sugar (packed) yields about 2.1 cups. 1 pound of powdered sugar yields 4 cups (the cleanest conversion). For commercial baking with bulk sugar: a 4-pound bag of granulated sugar gives 9 cups, a 4-pound bag of brown sugar gives 8.4 cups, and a 4-pound bag of powdered sugar gives 16 cups. The standard 1-pound bag of powdered sugar is sized specifically because 4 cups is the standard amount for most American frosting and icing recipes. For granulated sugar, the 4-pound bag is the common bulk size; the 2-pound bag is also common. Knowing the cup yield helps with recipe planning and storage container sizing.

Why do sugar types weigh different amounts per cup?

The weight differences come down to crystal size, density, and moisture content. Granulated white sugar has a uniform crystal structure that packs evenly. Powdered sugar is ground much finer, which traps more air between particles and lowers density per cup. Brown sugar contains molasses, which adds moisture and weight while causing particles to cling when packed. Coconut sugar and turbinado have larger, less uniform crystals. Date sugar is dried, ground dates with a fibrous structure that weighs less per volume. The density variations explain why baking benefits from weighing rather than measuring by cup; substituting one sugar for another cup-for-cup gives wildly different actual weights, which affects sweetness, texture, and moisture in the finished product.

When does the sugar pound-to-cup conversion matter most?

Bulk shopping is the most common case. Sugar comes in 1, 2, 4, and 5-pound bags, and converting to cups helps with recipe planning. Frosting and icing recipes often call for 'a pound of powdered sugar' (4 cups), making the conversion essential for the most common baking applications. Bread and cake baking uses cup measurements for sugar but the underlying weight matters for consistency; restaurant-scale recipes work in pounds because bulk ingredients are sold by weight. Nutrition tracking benefits from the gram conversion (1 cup granulated equals 200 g equals about 770 calories).
