Batch Scaling Around 400g Powdered / Confectioners' Sugar
| Batch Scale | Weight (g / oz) | US Cups & Spoons | Metric (mL) |
|---|---|---|---|
| Half Batch (0.5×) | 200g (7.05 oz) | 1 ⅔ cups | 394.3 mL |
| Standard (1×) | 400g (14.11 oz) | 3 ⅓ cups | 788.6 mL |
| 1.5× Batch | 600g (21.16 oz) | 5 cups | 1182.9 mL |
| Double Batch (2×) | 800g (28.22 oz) | 6 ⅔ cups | 1577.3 mL |

Measuring 400g of Powdered / Confectioners' Sugar in the Kitchen
Because 1 US Customary Cup (236.6 mL) of powdered / confectioners' sugar weighs 120g when measured unsifted spooned, 400 Grams (400g) translates to 3.33 US cups (3 ⅓ cups). By contrast, using the sifted measure (100g/cup — a 20g per-cup shift), 400g occupies 4 cups (4.00 cups).
Without a kitchen scale, measure 3 ⅓ cups (53.33 tablespoons total) using unsifted spooned technique. Spoon gently into the measuring cup and level flat. If your recipe calls for sifted powdered sugar, measure after sifting (100g/cup) or weigh directly.

Frequently Asked Questions
How many cups is 400 grams of powdered / confectioners' sugar? ▾
400 grams of powdered / confectioners' sugar (unsifted spooned, 120g per US cup) equals 3 ⅓ cups (3.33 US Customary Cups, 3.15 Metric 250 mL cups, or 53.33 tablespoons).
Why does powdered sugar contain cornstarch? ▾
Commercial confectioners sugar contains about 3% cornstarch as an anti-caking agent to prevent the microscopic particles from clumping.
Why do recipes specify sifted versus unsifted powdered sugar? ▾
Sifted powdered sugar traps significant air, dropping cup weight from 120g down to 100g—a 20% reduction in sweetness.
