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.
| Ingredient | 1½ Cups (g) |
|---|---|
| Olive Oil | 324g |
| Vegetable Oil | 327g |
| Coconut Oil | 327g |
| Canola Oil | 327g |
| Watercurrent | 360g |

Measuring Water Accurately
Why weight matters: 1 1/2 cups of water can weigh anywhere from 306g to 432g depending on how you measure it. The USDA standard is 360g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About water density: Water is the reference point for all density measurements. 1 cup (240ml) = 240g exactly. All liquid measurements in recipes assume water-like density unless specified. Use water as baseline for density calculations.
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 water?
1 1/2 cups of water weighs 360 grams (12.7 oz, 360ml). Based on USDA FoodData Central: 1 cup water = 240g, so 1 1/2 cups = 240 × 1.500 = 360g.
Is 1 1/2 cups of water the same weight every time?
The weight can vary slightly depending on measuring technique. Spooned and leveled gives 360g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 360g is the most reliable baseline for recipes.
How do I accurately measure 1 1/2 cups of water?
For accuracy, use a kitchen scale and weigh 360g of water. If using measuring cups, spoon the water 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 water compare to other ingredients?
1 1/2 cups of different ingredients varies significantly: Olive Oil = 324g, Vegetable Oil = 327g, Coconut Oil = 327g. This is because each ingredient has a different density.
