How to measure oat flour
How full the cup is and how firmly it is packed changes what it holds, so the same cup can weigh a little more or less in your kitchen. A scale gives the same result every time; the chart below converts any amount.
Source: 92 grams per US cup is the weight per cup in King Arthur Baking’s ingredient weight chart, entry “Oat Flour, 1 cup = 3 1/4 oz = 92 g”. A US cup is about 237 milliliters.
