0.25 Cups
SwitchExplanation
This page starts from weight ounces and estimates cups for cornstarch 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 in baking, where small measuring differences can change rise, set, and texture. Cornstarch can vary with fineness, aeration, and settling, so the page keeps one fixed basis for repeatable measuring.
