SwitchExplanation
This page handles the reverse question for cornstarch: starting from weight and estimating US cups. It uses the same cup conversion basis as the mirror page, only in reverse.
That keeps gram-based recipes and cup-based prep aligned to one explicit assumption. That is especially useful in baking, where small measuring differences can change rise, set, and texture. Very small gram amounts are too little to measure reliably in a cup, so cup measuring only becomes practical at larger weights. Cornstarch can vary with fineness, aeration, and settling, so the page keeps one fixed basis for repeatable measuring.
