Different flours pack differently, so their cup-to-gram weight varies. This chart lists the weight of one cup of each common flour, with its protein range.
| Flour | 1 cup (g) | Protein |
|---|---|---|
| All-purpose | 120 | 10 – 12% |
| Bread | 127 | 12 – 14% |
| Cake | 114 | 7 – 9% |
| Whole wheat | 120 | 13 – 14% |
| Pastry | 106 | 8 – 9% |
| Self-rising | 125 | 8 – 9% |
| 00 (Italian) | 120 | varies |
Weigh flour for consistency. Flour is the easiest ingredient to mis-measure by volume. A scale at these gram weights gives the same result every bake.
