Cups to grams
One US cup equals about 240 ml, but its weight in grams depends on the ingredient: roughly 125 g of all-purpose flour, 200 g of granulated sugar, 227 g of butter, or 240 g of milk. Always convert per ingredient rather than using a single figure.

Weights are approximate — flours and sugars vary with how they are scooped. Spoon into the cup and level off for best accuracy.
How to use the Cups to Grams converter (video)
Prefer to watch? This short video shows how to convert cups to grams and grams to cups by ingredient – pick your amount, choose the ingredient, and read the weight instantly.
Converting cups to grams is the easiest way to get accurate, repeatable baking results. This cups to grams converter works per ingredient, because a cup of flour and a cup of sugar do not weigh the same.
How to convert cups to grams
- Enter the amount and choose “cups”.
- Pick your ingredient from the list.
- Read the weight in grams and ounces instantly.
Cups to grams chart for common ingredients
| Ingredient | 1 cup in grams |
|---|---|
| All-purpose flour | 125 g |
| Granulated sugar | 200 g |
| Brown sugar (packed) | 220 g |
| Butter | 227 g |
| Honey | 340 g |
| Cocoa powder | 85 g |
Why the ingredient matters
A generic converter gets this wrong because density varies. Flour is light and fluffy, but honey is dense and heavy. Therefore Panvert uses a per-ingredient table, so your cups to grams results stay accurate every time.
Why measuring by weight beats cups
A cup measures volume; a gram measures weight. That difference matters most for dry, compressible ingredients. One cup of all-purpose flour can weigh anywhere from about 120 g (spooned in gently) to 150 g or more (scooped straight from the bag and tapped down) — a swing of roughly 25%. In a delicate cake or a batch of cookies, that is the difference between light and dense, or moist and dry. This is why professional bakers weigh their ingredients: a gram is always a gram, no matter who is measuring.
Weight matters less for thin liquids like water or milk, where a cup is reliably close to 240 g, but for flour, powdered sugar, cocoa and oats it is the single easiest way to make your baking consistent from one attempt to the next.
How to measure a cup correctly (without scales)
If you do not own a kitchen scale, technique is everything:
- Flour and powders: stir to loosen, spoon lightly into the cup, then level with the back of a knife. Never dip the cup into the bag — that packs in up to 20% extra.
- Brown sugar: pack it down firmly unless the recipe says otherwise.
- Liquids: use a clear jug and read the level at eye height.
The most common mistake is scooping flour, which adds too much and leaves bakes dry and heavy. When accuracy really counts, switch to grams — and if you are changing batch sizes, our recipe scaler and grams to cups converter do the maths for you.
Common cup amounts in grams (by ingredient)
| Amount | Flour | Sugar | Butter | Milk |

| ¼ cup | 31 g | 50 g | 57 g | 60 g |
| ⅓ cup | 42 g | 67 g | 76 g | 80 g |
| ½ cup | 63 g | 100 g | 113 g | 120 g |
| ¾ cup | 94 g | 150 g | 170 g | 180 g |
| 1 cup | 125 g | 200 g | 227 g | 240 g |
