In baking and cooking, there is frequently a need for calculation and conversion. If you frequently use powdered sugar or confectioners sugar in recipes, or if you are simply curious, you may wonder how much powdered sugar a box contains. Knowing this will simplify your powdered sugar purchasing decisions.
A one-pound or sixteen-ounce container of powdered or confectioners sugar contains roughly three-and-a-half cups of powdered sugar. Whether your recipe asks for sifted or un-sifted powdered sugar is an important factor to consider when utilizing this ingredient. If a recipe calls for sifted powdered sugar, the original recipe must be modified.
Let us explain how.
Do not mistake weight ounces with volume ounces when measuring powdered sugar. Know exactly how much you are purchasing. Everyone is aware that one cup equals eight ounces, right? In actuality, when measuring components for a recipe, 1 cup does not necessarily correspond to 8 ounces.
We know that 1 cup of water weighs 8 ounces, but because honey is more viscous than water, 1 cup of honey weighs 12 ounces. Powdered sugar directly from the box or plastic bag weighs 4 1/2 ounces per cup; therefore, a 1-pound box (or 16 ounces) provides approximately 3 1/2 cups of powdered sugar. If a recipe asks for powdered sugar, 4 ounces of powdered sugar will equal 1 dry measuring cup.

Powdered sugar becomes lighter and fluffier when sifted, so it occupies more space in the cup.
