SwitchExplanation
This page answers the kitchen question in weight terms: how much 1 US cup of baking soda 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 in baking, where small measuring differences can change rise, set, and texture. The mirror page uses the same ounce-per-cup conversion in reverse so both directions stay aligned.
