SwitchExplanation
This page answers the kitchen question in weight terms: how much 1 US cup of all-purpose flour 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 baking and dough work, where small differences in flour volume can change hydration and texture. The mirror page uses the same ounce-per-cup conversion in reverse so both directions stay aligned.
