Batch Scaling Around 100g Cornstarch
| Batch Scale | Weight (g / oz) | US Cups & Spoons | Metric (mL) |
|---|---|---|---|
| Half Batch (0.5×) | 50g (1.76 oz) | ⅓ cup + 2 ¾ tsp | 92.4 mL |
| Standard (1×) | 100g (3.53 oz) | ¾ cup + 1 ½ tsp | 184.8 mL |
| 1.5× Batch | 150g (5.29 oz) | 1 cup + 2 tbsp + 2 ¼ tsp | 277.3 mL |
| Double Batch (2×) | 200g (7.05 oz) | 1 ½ cups + 1 tbsp | 369.7 mL |

Measuring 100g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 100 Grams (100g) translates to 0.78 US cups (¾ cup + 1 ½ tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 100g occupies ⅔ cup + 1 tsp (0.69 cups).
Without a kitchen scale, measure ¾ cup + 1 ½ tsp (12.5 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.
