320 Grams of Sugar to Cups
320 grams of granulated sugar equals 1 ⅝ cups (1.6 US cups), based on 200 g per cup (level cup). In the kitchen, measure 1 cup + 10 tbsp. For best results, weigh granulated sugar with a scale — cup measurements vary with how the cup is filled.
Batch amounts are where cup measuring drifts furthest — small per-cup errors compound across 2 cups, so a scale pays off here.

How to measure 320 g of granulated sugar without a scale
