Convert Cups to Grams: Oat Flour
Convert cups of oat flour to grams with this complete reference table. 1 cup of oat flour = 92g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because oat flour density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Oat flour is lighter than all-purpose flour. 1 cup = 92g. Can be made at home by blending rolled oats. Has a mild, slightly sweet flavor. Good for pancakes, muffins.
About Oat Flour Density
The density of oat flour determines how much it weighs per unit of volume. At 0.383g/ml, 1 US cup (240ml) of oat flour weighs 92g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
