Volume vs Weight
Volume measurements vary wildly depending on how flour is settled in the cup. Weight in grams is immutable and accurate across all kitchens.
Flour density variations
Different flours have distinct bulk densities. Whole wheat flour contains bran flakes that create air pockets, making it lighter per cup than finely milled 00 flour or dense semolina.
Our reference weight chart uses standard laboratory density benchmarks for common baking ingredients:
| Ingredient | 1 US Cup Weight | Density (g/ml) |
|---|---|---|
| All-Purpose Flour | 120 g | 0.51 |
| Bread Flour | 127 g | 0.54 |
| Whole Wheat Flour | 113 g | 0.48 |
| Water | 237 g | 1.00 |
