320 Grams of Flour to Cups
320 grams of all-purpose flour equals 2 ⅔ cups (2.67 US cups), based on 120 g per cup (spoon-and-level method). In the kitchen, measure 2 cups + 11 tbsp. For best results, weigh all-purpose flour 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 3 cups, so a scale pays off here.

Seeing a different answer elsewhere? Sources disagree on flour: King Arthur's spoon-and-level standard is 120 g per cup (our number, giving 2 ⅔ cups), while USDA-based tables use 125 g (giving 2 ½ cups, 2.56 cups). Both are correct for their measuring method — see how we measure.
How to measure 320 g of all-purpose flour without a scale
Spoon flour into the cup with a spoon, then level the top with a straight edge — never scoop the cup into the bag. Scooping compresses flour and can pack in 20–30% more (140 g+ instead of 120 g), which is the single most common reason baked goods turn out dry. Sifted flour runs lighter still, about 110 g per cup.
