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.

| Powdered Sugar | 180g |
| Granulated Sugarcurrent | 300g |
| Caster Sugar | 315g |
| Brown Sugar (packed) | 330g |

Measuring Granulated Sugar Accurately
Why weight matters: 1 1/2 cups of granulated sugar can weigh anywhere from 255g to 360g depending on how you measure it. The USDA standard is 300g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About granulated sugar density: Granulated white sugar is the most consistent of all sugars — 1 cup = 200g regardless of spooning or packing. The uniform crystal size makes it very consistent to measure. Standard sugar for most baking recipes.
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.
Frequently Asked Questions
How many grams is 1 1/2 cups of granulated sugar?
1 1/2 cups of granulated sugar weighs 300 grams (10.58 oz, 360ml). Based on USDA FoodData Central: 1 cup granulated sugar = 200g, so 1 1/2 cups = 200 × 1.500 = 300g.
Is 1 1/2 cups of granulated sugar the same weight every time?
The weight can vary slightly depending on measuring technique. Spooned and leveled gives 300g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 300g is the most reliable baseline for recipes.
How do I accurately measure 1 1/2 cups of granulated sugar?
For accuracy, use a kitchen scale and weigh 300g of granulated sugar. If using measuring cups, spoon the granulated sugar lightly into a 1½ Cups measuring cup and level off the top with a straight edge. Avoid scooping directly from the container, which compacts the ingredient and adds extra weight.
How does 1 1/2 cups of granulated sugar compare to other ingredients?
1 1/2 cups of different ingredients varies significantly: Powdered Sugar = 180g, Granulated Sugar = 300g, Caster Sugar = 315g. This is because each ingredient has a different density.
