Why weigh whole cornmeal instead of measuring cups?
A cup measures volume, but recipes really care about how much whole cornmeal you add by weight. One US cup of whole cornmeal is taken as 138 g here, cited from King Arthur Baking for the exact chart form “whole cornmeal”, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on product form and how the whole cornmeal is packed, so a kitchen scale is the reliable way to hit the same result every time.
