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.
