📐 Formula

1 cup = 16 tablespoons = 48 teaspoons. Grams = Cups × Grams-per-cup (ingredient-specific density)

How to Use the Cups to Grams Converter

1

Select the ingredient

Choose from the dropdown list of 50+ common baking and cooking ingredients. Density varies enormously — 1 cup of flour is not the same weight as 1 cup of sugar, honey, or butter.

2

Enter the volume amount

Input your quantity in cups, tablespoons, or teaspoons. The calculator supports all standard US volume measures and converts to grams, ounces, and kilograms.

3

Read the weight result

The result gives you the precise gram weight for accurate measuring. For baking especially, weighing ingredients rather than scooping produces significantly more consistent results.

Why Volume-to-Weight Conversion Matters in Baking

Baking is precision chemistry. A cup of all-purpose flour can weigh anywhere from 110g to 160g depending on how it was scooped — sifted and spooned flour weighs about 120g per cup; packed flour pressed into a measuring cup can reach 160g. That 40g discrepancy in a cake recipe can be the difference between tender and dense. Professional and most international recipes use gram weights for exactly this reason: weight is unambiguous, volume is not.

The most common volume-to-weight conversions in baking: all-purpose flour (1 cup = 125g), granulated sugar (1 cup = 200g), brown sugar packed (1 cup = 220g), powdered sugar sifted (1 cup = 120g), butter (1 cup = 227g), honey (1 cup = 340g), rolled oats (1 cup = 90g), cocoa powder (1 cup = 85g), milk (1 cup = 240g). Notice how dramatically these vary — honey weighs nearly three times as much as rolled oats per cup.

Tablespoon and Teaspoon Conversions

For smaller quantities — spices, leavening agents, extracts — volume measures are often practical enough. Key reference: 1 US tablespoon = 14.79ml (approximately 15ml); 1 teaspoon = 4.93ml (approximately 5ml); 3 teaspoons = 1 tablespoon; 16 tablespoons = 1 cup. For critical measurements like baking powder, yeast, and salt, even small errors affect results — use a digital scale for quantities above 5g and a measuring spoon set calibrated to 5ml teaspoon for smaller amounts.

Frequently Asked Questions

Grams are more accurate. A cup of flour can weigh anywhere from 120g to 160g depending on how it's scooped. Weighing ingredients ensures consistent results, especially important for baking where precision matters.
1 cup of all-purpose flour is approximately 125 grams (using the spoon-and-level method). If you scoop directly from the bag, it can be closer to 150–160g due to packing.
There are exactly 16 tablespoons in 1 cup. 1 tablespoon = 3 teaspoons. 1 cup = 48 teaspoons = 16 tablespoons = 8 fluid ounces = 240ml (for water).
1 cup of granulated white sugar = approximately 200 grams. Powdered (confectioners') sugar = 120 grams per cup. Brown sugar, packed = 220 grams per cup. The variation occurs because sugar density differs by type and how tightly it is packed. Using a kitchen scale is far more accurate than volume for baking.
1 cup of butter = 227 grams (2 US sticks). ½ cup = 113 grams (1 stick). ¼ cup = 57 grams. European recipes often use 250g per cup as a rough equivalent. Butter should be measured by weight for baking accuracy, especially in laminated doughs (croissants, puff pastry) where fat content is critical.
