1½ Cups of Different Ingredients — Weight Comparison
1 1/2 cups of different ingredients varies widely in weight because each has a different density. This matters when substituting ingredients in recipes.

Measuring Cornstarch Accurately
Why weight matters: 1 1/2 cups of cornstarch can weigh anywhere from 163g to 230g depending on how you measure it. The USDA standard is 192g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About cornstarch density: Cornstarch (corn flour in UK) is a fine white powder. 1 cup = 128g. Used as a thickener for sauces and gravies. 1 tablespoon cornstarch = 2 tablespoons all-purpose flour as a thickener.
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.
