| Standard (1×) | 30g (1.06 oz) | ⅓ cup | 77.1 mL |
| 1.5× Batch | 45g (1.59 oz) | ½ cup | 115.7 mL |
| Double Batch (2×) | 60g (2.12 oz) | ⅔ cup | 154.3 mL |

Measuring 30g of Oat Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of oat flour weighs 92g when measured spooned & leveled, 30 Grams (30g) translates to 0.33 US cups (⅓ cup). By contrast, using the scooped from bag measure (104g/cup — a 12g per-cup shift), 30g occupies ¼ cup + 1 ¾ tsp (0.29 cups).
Without a kitchen scale, measure ⅓ cup (5.22 tablespoons total) using spooned & leveled technique. Spoon lightly and level. Oat flour is exceptionally light and fluffy; shaking the cup causes severe settling.
