How this works
Powdered sugar has a density of about 0.478 g/mL (king arthur baking: 1 cup = 113g). That means 1 mL of powdered sugar weighs 0.478 grams.
Cups = grams × 0.0088
Note: Unsifted; sifted is closer to 0.42 g/mL.
Why a cup of powdered sugar doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of powdered sugar can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.
