Explanation

This page starts from weight ounces and estimates cups for rolled oats 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 for batch cooking and portion planning, where grain volume and weight need to stay aligned. Rolled Oats can vary with grain shape and how the grains settle in the cup, so the page keeps one explicit basis for repeatable prep.
