SwitchExplanation
This page starts from weight ounces and estimates cups for powdered sugar using the same ounce-per-cup conversion as the mirror page. That keeps the forward and reverse routes numerically aligned.
It is useful when a recipe or label gives ounces by weight but prep is measured in cups. That is especially useful for frosting, dusting, fillings, and baking prep where sifted vs unsifted powder can change the measured volume. Powdered Sugar can clump, aerate, and settle differently depending on how it is sifted or spooned, so the page keeps one explicit basis instead of mixing preparation styles.
