| Standard (1×) | 25g (0.88 oz) | 3 tbsp + ½ tsp | 46.2 mL |
| 1.5× Batch | 37.5g (1.32 oz) | ¼ cup + 2 tsp | 69.3 mL |
| Double Batch (2×) | 50g (1.76 oz) | ⅓ cup + 2 ¾ tsp | 92.4 mL |

Measuring 25g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 25 Grams (25g) translates to 0.20 US cups (3 tbsp + ½ tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 25g occupies 2 tbsp + 2 ¼ tsp (0.17 cups).
Without a kitchen scale, measure 3 tbsp + ½ tsp (3.13 tablespoons total) using spooned & leveled technique. Cornstarch packs easily into a solid cake when pressed; scoop gently with a spoon and sweep level with a straightedge.
