About This Tool
The Cups to Grams Calculator converts culinary volume measurements (US cups) into exact weight measurements (grams and ounces) based on calibrated ingredient densities.
### Why Volume Measurements Fail in Baking Measuring dry ingredients like flour by volume is inherently inconsistent. Scooping directly from a bag compacts the flour, yielding up to 150 grams per cup, while sifted flour might weigh only 110 grams. Standard culinary recipes calibrate one level cup of all-purpose flour at 120 grams. Measuring by weight with a kitchen scale ensures consistent dough hydration and crumb structure.
### Calibrated Ingredient Densities This converter uses the following established density baselines per level US cup: - **All-Purpose Flour**: 120 g (4.2 oz) - **Granulated White Sugar**: 200 g (7.1 oz) - **Packed Brown Sugar**: 220 g (7.8 oz) - **Powdered Confectioners Sugar**: 120 g (4.2 oz) - **Butter**: 227 g (8.0 oz / 2 standard US sticks) - **Rolled Oats**: 90 g (3.2 oz) - **Almond Flour**: 96 g (3.4 oz) - **Cocoa Powder**: 100 g (3.5 oz)
### Worked Calculation Example Converting 2.5 cups of packed brown sugar: $$\text{Weight} = 2.5 \times 220\text{ g} = 550.0\text{ grams}$$ $$\text{Ounces} = \frac{550.0}{28.3495} \approx 19.4\text{ oz}$$

How to Use
- 1
Enter the recipe amount in US cups using the number input.
- 2
Select your baking ingredient from the density dropdown list.
- 3
Review the primary weight in grams alongside the ounce and milligram breakdowns.
- 4
Tare your kitchen scale with your mixing bowl and measure the indicated gram weight.
Frequently Asked Questions
Why does 1 cup of flour weigh less than 1 cup of sugar?
Flour is porous with low bulk density (approx 120g per cup), while granulated sugar crystals pack tightly together with higher bulk density (approx 200g per cup).
Does this calculator use US Customary cups or metric cups?
The converter uses standard US Customary cups (236.6 ml). A metric cup (250 ml) holds roughly 5% more volume.
Are any recipe details stored or transmitted?
No. The conversion formula runs completely on your local device without network requests.
