Cups to Grams
1 cup of all-purpose flour = 125 g.
1 cup of granulated sugar = 200 g.
1 cup of butter = 227 g · 1 cup of honey = 340 g.
"How many grams in a cup?" has no single answer, because a cup is a measure of volume and a gram is a measure of weight. The same cup holds 90 g of cocoa powder but 340 g of honey — almost four times the mass. The chart below gives exact gram weights for every common ingredient at 1 cup down to 1/4 cup.

The Three Density Groups
Once you see the pattern, you can estimate any ingredient by which group it belongs to:
- Light (85–130 g/cup): flours, cocoa, oats, powdered sugar, cornstarch. These airy powders trap a lot of empty space, so a full cup is relatively light.
- Medium (185–245 g/cup): granulated sugar, oils, milk, water, yogurt, rice. Most everyday liquids and crystalline solids land here.
- Heavy (250–340 g/cup): peanut butter, honey, maple syrup, brown sugar packed. Sticky, concentrated, or compressed ingredients pack maximum mass per cup.
Common Cup Amounts in Grams (Flour & Sugar)
The two most-searched ingredients, broken out for quick reference:
| Cups | All-purpose flour | Granulated sugar |
|---|---|---|
| 1/4 cup | 31 g | 50 g |
| 1/3 cup | 42 g | 67 g |
| 1/2 cup | 63 g | 100 g |
| 2/3 cup | 83 g | 133 g |
| 3/4 cup | 94 g | 150 g |
| 1 cup | 125 g | 200 g |
| 1 1/2 cups | 188 g | 300 g |
| 2 cups | 250 g | 400 g |
Why Spoon-and-Level Matters
Every flour figure on this page assumes the spoon-and-level method: spoon flour loosely into the cup, then level the top with a straight edge. If you instead scoop the cup straight into the bag, you compress the flour and can pack in 150–160 g per cup — up to 30 g extra. That single difference is the most common reason home-baked cookies and cakes come out dry.

FAQ
How many grams is 1 cup?
It depends entirely on the ingredient. 1 US cup of all-purpose flour is 125 g, 1 cup of granulated sugar is 200 g, 1 cup of butter is 227 g, and 1 cup of honey is 340 g. A cup measures volume (236.6 ml); grams measure weight, so dense ingredients pack far more grams into the same cup.
Why can't I use one number for all ingredients?
Because density varies enormously. Cocoa powder is light (90 g per cup) while honey is heavy (340 g per cup) — nearly a 4× difference for the exact same cup. Using a single conversion would throw off any recipe where weight matters, especially baking.
Are these US cups or metric cups?
All values on this page use the US cup (236.588 ml), which is the standard in American recipes. A metric cup is 250 ml, about 5.6% larger. If your recipe uses metric cups, multiply the gram values below by 1.057.
Should I spoon or scoop the flour?
Spoon and level. The 125 g per cup figure assumes you spoon flour into the cup and level it off. Scooping the cup directly into the bag compacts the flour and can add 20–30 g per cup — enough to make baked goods dry and dense.
What's the most accurate way to measure?
A kitchen scale. Weighing in grams removes the cup-packing guesswork entirely and is why most professional and European recipes are written by weight. For high-precision baking (bread, macarons, laminated dough) a scale is strongly recommended.
Does 1 cup of liquid weigh the same as 1 cup of water?
Roughly, for water-based liquids. 1 cup of water is 237 g, milk is 245 g, and most thin liquids land within a few grams. Thick or sugary liquids are heavier — 1 cup of honey is 340 g and maple syrup is 312 g because dissolved sugar adds mass.
