| Standard (1×) | 30g (1.06 oz) | ¼ cup | 62.3 mL |
| 1.5× Batch | 45g (1.59 oz) | ⅓ cup + 1 tbsp | 93.4 mL |
| Double Batch (2×) | 60g (2.12 oz) | ½ cup + 1 ¼ tsp | 124.5 mL |

Measuring 30g of Cake Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cake flour weighs 114g when measured spooned & leveled, 30 Grams (30g) translates to 0.26 US cups (¼ cup). By contrast, using the sifted measure (100g/cup — a 14g per-cup shift), 30g occupies ¼ cup + 2 ½ tsp (0.30 cups).
Without a kitchen scale, measure ¼ cup (4.21 tablespoons total) using spooned & leveled technique. Cake flour is milled extra fine and clumps easily in humidity; sift or whisk thoroughly before spooning into a measuring cup.
