Why weight matters: 1 1/2 cups of unsalted butter can weigh anywhere from 289g to 409g depending on how you measure it. The USDA standard is 340.5g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About unsalted butter density: Butter is nearly as dense as water when melted (0.946 g/ml). 1 cup solid butter = 227g = 2 sticks US. Softened butter and solid butter weigh the same per cup — measuring by weight is most reliable. Melted butter = slightly less by volume.
About 1½ Cups as a Measurement
1 1/2 cups = 24 tablespoons = 360ml. This is the standard flour amount for a dozen standard-size cookies or a single-layer 8-inch cake. It bridges the gap between single-cup and double-cup recipe scales.
One and a half cups appears most often in cookie dough recipes (flour), quick bread recipes (oats or mix-ins), and pasta sauce recipes (liquid ingredients). It equals 360ml or 12 fluid ounces.
