3 Cups of Butter in Grams
3 cups of butter weighs 681 grams (about 24 oz), based on 227 g per US cup (level cup). That's the same as 48 tablespoons of butter. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
3 cups is batch territory — a cup-measuring error is multiplied three times over, which for butter is the difference between 681 g and something noticeably off. Weigh it if you can.

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.
