About
Powdered sugar is finely ground sugar mixed with starch, packing roughly 4.7 ounces (132 g) into a single cup.
Powdered sugar has a typical bulk density of 0.56 grams per milliliter, which means it holds a lot of trapped air between its fine particles. A standard one-pound (454 g) box occupies about 3.4 US cups of space. Because it is milled so finely and mixed with a little starch to prevent clumping, it takes up far more volume than the same weight of table sugar. It pours loosely, but it can settle and pack down if shaken or pressed.
From Wikipedia
Powdered sugar, also called confectioners' sugar and icing sugar, is a finely ground sugar produced by milling granulated sugar into a powdered state. It usually contains between 2% and 5% of an anti-caking agent—such as corn starch, potato starch or tricalcium phosphate—to absorb moisture, prevent clumping, and improve flow.
