Why does powdered / confectioners sugar weigh what it weighs?
Sugars vary in density depending on crystal size, moisture content, and whether they are packed. Granulated sugar is dense and uniform; powdered sugar is fluffy and aerated; brown sugar gains weight as it is packed into the cup. Liquid sweeteners like honey are heavier still because water and dissolved sugars take up less space than dry crystals.
For powdered / confectioners sugar specifically, 1 cup weighs 113g. That is the figure to plug into recipes calling for cup measurements when you want gram precision. ChefVault stores this density (and 118 others) so you never have to look it up twice.
Recipes that originated outside the United States almost always specify weight in grams. Translating these to US cup measurements introduces error in every step. The ChefVault app handles the math automatically — paste a recipe, hit convert, get a clean weight-based version.
