SwitchExplanation
This page answers the kitchen question in weight terms: how much 1 US cup of powdered sugar weighs in ounces. It converts cup volume into weight ounces using one ingredient-specific factor instead of a generic chart.
It is measuring 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 mirror page uses the same ounce-per-cup conversion in reverse so both directions stay aligned.
