Cup & Gram

320 Grams of Butter to Cups

320 grams of butter equals 1 ⅜ cups (1.41 US cups), based on 227 g per cup (level cup). In the kitchen, measure 1 cup + 7 tbsp. For best results, weigh butter 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 butter without a scale

In the US, butter is easiest to measure by the wrapper: one stick is ½ cup = 8 tbsp = 113 g, and the wrapper is printed with tablespoon marks. For amounts that aren’t clean stick fractions, weigh it — cutting soft butter into a measuring cup traps air pockets.
