}Explanation
Convert 1 US cup of powdered sugar to ounces by weight with an ingredient-specific cup reference.
The result is mass, not fluid ounces. That is especially useful for frosting, dusting, fillings, and baking prep where sifted vs unsifted powder can change the measured volume. The reverse conversion uses the same ounce-per-cup reference.

Methodology
Powdered Sugar: cups to ounces by weight evidence
Powdered sugar, also known as icing sugar or confectioner’s sugar, is finely milled sugar blended with a small amount of starch to prevent clumping. Its ultra-fine texture allows it to dissolve rapidly, making it useful when quick sweetness integration is required.
Practical use: Powdered sugar is used as a fast-dissolving sweetening agent when rapid integration is needed. It can be incorporated dry, pre-dissolved, or used for surface finishing, contributing sweetness without altering flavor balance.
Ingredient characteristics: Powdered sugar provides clean, direct sweetness with no aromatic character. The perception is soft and immediate due to its fine particle size, contributing sweetness without adding body, acidity, or bitterness.
Direction calculation: Powdered Sugar — 1 US cup equals 3.985960952 ounces by weight. Reference: 113 g/US cup. Source basis: King Arthur weight chart (unsifted)
Among the 6 reviewed records labeled Salts & Sugars (Rimming/Specialty), the nearest factor to Powdered Sugar is Rock Salt at 192 g/cup: a difference of 79 g/cup (69.9% relative to Powdered Sugar). The observed range in this labeled group is Powdered Sugar at 113 g/cup to Salt at 288 g/cup.
