1 1/2 Cups of Butter in Grams
1 1/2 cups of butter weighs 341 grams (about 12 oz), based on 227 g per US cup (level cup). That's the same as 24 tablespoons of butter. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
1 1/2 cups is one full cup plus a half (227 g + 114 g). At this size the fill method starts to matter: the error in each cup is added, not averaged.

How to measure 1 1/2 cup of butter
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.
