Grams to Cups Converter
Exact US cups and spoons for 20 baking ingredients. Pick one, type the amount, and see which measuring cups to use.
Tip: Spoon flour into the cup and level it with a knife. Scooping straight from the bag packs in up to 30 g extra.
To convert grams to cups, divide the grams by the ingredient's weight per cup. One US cup holds about 125 g of all-purpose flour, 200 g of granulated sugar, 227 g of butter or 237 g of water. So 250 g is 2 cups of flour but only 1 ¼ cups of sugar.

Grams to cups by ingredient
How to convert grams to cups
Divide the weight in grams by the weight of one cup of that ingredient.
cups = grams ÷ grams per cup
For example, 300 g of all-purpose flour ÷ 125 g per cup = 2.4 cups, which you can measure as 2 ⅓ cups + 1 tablespoon. The converter above does this for you and also shows which standard measuring cups add up to the amount, so you don’t need a ⅔ or ¾ cup measure.
To go the other way, multiply: 1 ½ cups of sugar × 200 g = 300 g. Switch the converter to Cups → Grams for that.
Why grams and cups don’t convert one-to-one
A gram is a unit of weight. A cup is a unit of volume. How much a cup weighs depends on how dense the ingredient is and how much air is trapped in it:
- Flour is light and fluffy, so a cup weighs about 125 g.
- Granulated sugar is made of small dense crystals, so a cup weighs about 200 g.
- Honey is a thick liquid with no air in it, so a cup weighs about 339 g.
That’s why “1 cup = 250 g” or “1 cup = 240 g” rules of thumb don’t work for baking. They’re only close for water-like liquids.
Measure the way the recipe was written
The weights on this site assume the standard American methods:
- Flour, powdered sugar and cocoa: stir, spoon into the cup, then level the top with a knife. Don’t tap or press.
- Granulated sugar, rice and oats: scoop and level.
- Brown sugar: press firmly into the cup until it holds its shape.
- Butter, peanut butter and cream cheese: soften, press into the cup to remove air pockets, then level.
- Liquids: use a clear liquid measuring cup on a flat counter and read it at eye level.
If you scoop flour straight from the bag, a “cup” can hold 20–30 g more than the recipe expects. That’s often the difference between a soft cookie and a dry one.
Where our numbers come from
Each ingredient has one weight per cup, taken from USDA FoodData Central household measures or, where we say so, King Arthur Baking’s ingredient weight chart. Every page on the site uses that same number, so the answer for 100 g of flour is the same in the converter, the charts and the guides. The full list and the sources are on how we calculate.

Questions
How many grams are in a cup?
It depends on the ingredient, because a cup measures volume and grams measure weight. One US cup holds about 125 g of all-purpose flour, 200 g of granulated sugar, 220 g of packed brown sugar, 227 g of butter, 237 g of water and 244 g of milk. See the full list on how many grams in a cup.
How many cups is 100 grams?
100 grams is ¾ cup + 1 tablespoon of all-purpose flour, ½ cup of granulated sugar, or about 7 tablespoons (just under ½ cup) of butter. Every ingredient is listed on the 100 grams to cups page.
How many cups is 200 grams?
200 grams is exactly 1 cup of granulated sugar, 1 ½ cups + 1 ½ tablespoons of all-purpose flour, and ¾ cup + 2 tablespoons of butter. See 200 grams to cups.
Is 1 cup 250 grams?
Only for some ingredients, and only roughly. A metric cup (used in Australia, Canada and the UK) is 250 ml, which holds about 250 g of water. A US cup is 236.6 ml. For dry ingredients the weight is very different, for example 125 g for a US cup of flour.
Why does the converter ask for an ingredient?
Because the answer changes with the ingredient. Flour holds a lot of air, so a cup of it weighs about 125 g. Sugar packs tighter and weighs 200 g, and honey weighs 339 g. Using one number for everything can put a recipe off by half.
Which cup does this converter use?
The US customary cup (236.6 ml) by default. Tap Metric 250 ml in the converter if your recipe uses metric cups.
