Convert Cups to Grams: Buckwheat Flour
Convert cups of buckwheat flour to grams with this complete reference table. 1 cup of buckwheat flour = 120g (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 buckwheat flour density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Buckwheat flour: 1 cup = 120g. Despite the name, buckwheat is gluten-free (not related to wheat). Has a distinctive earthy, slightly bitter flavor. Used in Japanese soba noodles, crepes, and pancakes. Source: USDA FoodData Central FDC 20008.
About Buckwheat Flour Density
The density of buckwheat flour determines how much it weighs per unit of volume. At 0.5g/ml, 1 US cup (240ml) of buckwheat flour weighs 120g 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.
