Batch Scaling Around 500g Cornstarch
| Batch Scale | Weight (g / oz) | US Cups & Spoons | Metric (mL) |
|---|---|---|---|
| Half Batch (0.5×) | 250g (8.82 oz) | 1 ¾ cups + 3 tbsp + ¾ tsp | 462.1 mL |
| Standard (1×) | 500g (17.64 oz) | 3 ¾ cups + 2 tbsp + 1 ½ tsp | 924.2 mL |
| 1.5× Batch | 750g (26.46 oz) | 5 ¾ cups + 1 tbsp + 2 ¼ tsp | 1386.3 mL |
| Double Batch (2×) | 1000g (35.27 oz) | 7 ¾ cups + 1 tbsp | 1848.3 mL |
| Triple Batch (3×) | 1500g (52.91 oz) | 11 ⅔ cups + 2 ½ tsp | 2772.5 mL |
Measuring 500g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 500 Grams (500g) translates to 3.91 US cups (3 ¾ cups + 2 tbsp + 1 ½ tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 500g occupies 3 ⅓ cups + 1 tbsp + 2 ½ tsp (3.45 cups).
Without a kitchen scale, measure 3 ¾ cups + 2 tbsp + 1 ½ tsp (62.5 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.
