}Explanation
Convert 1 US cup of tapioca starch to ounces by weight with an ingredient-specific cup reference.
The result is mass, not fluid ounces. That is especially useful in baking, where small measuring differences can change rise, set, and texture. The reverse conversion uses the same ounce-per-cup reference.
