How many grams in a cup depends entirely on what you're measuring. A cup is a fixed volume, 236.6 ml in the US, but the weight that fills it changes with density. Here's how many grams are in a cup of the most common baking ingredients:
| 1 US cup of | Grams in a cup |
|---|---|
| All-Purpose Flour | 120 g |
| Granulated Sugar | 198 g |
| Brown Sugar | 213 g |
| Butter | 227 g |
| Powdered Sugar | 113 g |
| Water | 237 g |
| Fresh Milk | 244 g |
| Old-Fashioned Rolled Oats | 89 g |
| Long-Grain White Rice | 185 g |
| Honey | 340 g |
| Unsweetened Cocoa Powder | 84 g |
| Vegetable Oil | 198 g |
So when someone asks how many grams in a cup, the honest answer is: it depends on the ingredient. All-purpose flour is 120g per cup, powdered sugar is 113g, granulated sugar is 198g, uncooked long-grain rice is about 185g and honey is about 340g in the same cup volume.
Whether you type it as 100 grams to cups or 100g to cups, the answer changes with what is in the cup. 100g in cups ranges from a third of a cup of honey to more than a full cup of cocoa powder:
| 100 grams of | Equivalent in US cups |
|---|---|
| Flour | 0.83 cups |
| Sugar | 0.51 cups |
| Brown Sugar | 0.47 cups |
| Butter | 0.44 cups |
| Powdered Sugar | 0.88 cups |
| Rolled Oats | 1.12 cups |
| Water | 0.42 cups |
| Honey | 0.29 cups |
| Cocoa Powder | 1.19 cups |
How much is 100 grams in cups isn't a single figure, 100g of oats nearly fills a cup, while 100g of honey barely fills a third. Always match the ingredient. For a full breakdown, see our 100 grams to cups page.

Brown Sugar, Powdered Sugar, Cocoa & Honey
Brown sugar (packed): 213 g per cup; press it evenly into the cup.
Powdered sugar: 113 g per cup when unsifted and not packed.
Cocoa powder: 84 g per cup when spooned and leveled.
Honey: 340 g per cup, the heaviest common ingredient.
Oats, Rice, Milk & Oil
Rolled oats: 89 g per cup for old-fashioned or quick-cooking oats.
Uncooked long-grain white rice: about 185 g per cup.
Fresh milk: 244 g per cup, from its measured density of 1.03 g/mL. Water is about 237 g per US cup, so a cup of milk weighs slightly more than a cup of water.
Vegetable oil: 198 g per cup.
When a recipe uses cups but you want to weigh instead, this cups to grams chart gives you the exact grams. Weighing is faster and more accurate than scooping, so many bakers convert cups to grams before they start.

½, ¼ & ¾ Cup to Grams
| Cup amount | All-purpose flour | Granulated sugar | Butter |
|---|---|---|---|
| 1/4 cup | 30 g | 50 g | 57 g |
| 1/2 cup | 60 g | 99 g | 114 g |
| 3/4 cup | 90 g | 148 g | 170 g |
| 1 cup | 120 g | 198 g | 227 g |
| 1 1/2 cups | 180 g | 297 g | 340 g |
| 2 cups | 240 g | 396 g | 454 g |
So 1 cup to grams has no single value: 1 cup flour in grams is 120 g, but 1 cup sugar in grams is 198 g. Scale it up and the gap widens, 2 cups flour in grams is 240 g and 3 cups flour in grams is 360 g, while 2 cups in grams of sugar comes to 396 g.
Going the other way for smaller amounts: 1/4 cup to grams is 30 g of flour or 50 g of sugar, 1/2 cup sugar in grams is 99 g, and half a cup in grams of flour is 60 g. Multiply the cup fraction by the ingredient's grams-per-cup figure and you have it.
What Is a Cup? (US vs Metric vs UK)
A cup measures the space an ingredient takes up, not what it weighs, and the word covers four different volumes depending on where the recipe was written:
- US customary cup: 236.6 ml, the standard for American recipes.
- US legal cup: 240 ml, used on nutrition labels.
- Metric cup: 250 ml, common in Australia, Canada and Europe.
- UK legacy cup: 284 ml, found in older British recipes.
The spread matters more than it looks. A metric cup of flour holds about 127 g against 120 g for a US cup, small on one cup, half a cup out by the time you have measured six. Everything on this site uses the US customary cup (236.6 ml), and says so on every page.
What Is a Gram?
A gram is a thousandth of a kilogram, and it describes one thing only: how much matter is there. It does not care how the ingredient is packed, how humid the kitchen is, or which cup you own.
That is the whole reason a grams to cups conversion needs a third number. Grams tell you the weight, cups tell you the volume, and the ingredient's density is what connects them. Without knowing the ingredient, the question has no answer.
Cups = Grams ÷ (Density × 236.6)The core grams to cups formula
There is no universal gram to cup ratio to memorise. There is one division, done against whatever the ingredient weighs per cup:
Cups = Grams ÷ Grams-per-cup of the ingredientOr from raw density: Cups = Grams ÷ (Density in g/ml × 236.6)
Worked examples:
Flour: 240g ÷ 120 = 2 cups
Sugar: 100g ÷ 198 = 0.51 cups
Butter: 227g ÷ 227 = 1 cup
Honey: 340g ÷ 340 = 1 cup
The grams-per-cup figure is the only part you have to look up, and it is the part most charts get wrong or leave unsourced. Ours are listed with their source on the ingredient density page.
Every grams to cups chart, including this one, publishes a single number for a cup of flour. That number assumes a measuring technique. Change the technique and the same cup holds a different amount of flour:
1
Sifted, then spooned: about 106 g
Sifting forces air between the particles. The cup looks full and is holding about 12% less flour than the recipe expects.
2
Fluffed, spooned and levelled: 120 g
The reference figure on this site. Loosen the flour, spoon it in without pressing, level the top with a straight edge.
3
Scooped straight from the bag: up to 150 g
Pushing the cup into the bag compresses the flour ahead of it. That is 25% more flour than the same cup measured by spooning.
Across a four-cup recipe, the difference between scooping and spooning is around 120 g of extra flour, roughly an additional cup that nobody intended to add. It is why the same cookie recipe turns out soft for one person and dry for another, and why the gram figure in a recipe is the one worth trusting.
A cup of flour is the extreme case, but the same effect applies to cocoa, powdered sugar and anything else that compresses. Granulated sugar, butter and liquids barely move, which is why their conversions are reliable either way.
If a recipe gives you grams, use the grams. Convert to cups when the recipe leaves you no choice, and match the measuring method the chart assumes.
Six things that quietly change the answer, and what to do about each one:
The recipe means a different cup
An Australian recipe's cup is 250 ml, not 236.6 ml. If the source is not American, every cup figure on this page is about 5% low for that recipe.
"Sifted flour" and "flour, sifted" differ
Word order decides the order of operations. Sift first and you measure less flour; measure first and the sifting changes nothing about the weight.
Brown sugar is measured packed
Our 213 g assumes it is pressed in firmly enough to hold the cup's shape when tipped out. Loose brown sugar is closer to 145 g and will leave a batter dry.
The flour is not all-purpose
Cake flour runs lighter per cup and bread flour heavier. Swapping one for another changes the weight of a cup, so a recipe written in cups does not transfer between them.
Liquids are read from above
Looking down at a measuring jug reads high by a noticeable margin. Set it on the counter and read the meniscus at eye level, or weigh the liquid instead.
Rounding stacks up
Each conversion here is rounded for the kitchen. On one ingredient that is invisible; across a full recipe converted piece by piece, the errors accumulate in the same direction.

Quick answers to your most common gram-to-cup conversion questions:
How many grams are in a cup of flour?▾
One cup of all-purpose flour is 120 grams when spooned and leveled. If you scoop directly, you can pack in up to 150g, which is why weighing is more reliable.
How many cups is 100 grams?▾
It depends on the ingredient. 100 grams to cups is about 0.83 cups of flour, 0.51 cups of sugar, or 0.44 cups of butter. Lighter ingredients like oats reach over a cup at 100g.
How much is 1 cup in grams?▾
1 cup in grams varies by ingredient: 120g flour, 198g sugar, 227g butter, 244g milk. There's no single answer because a cup measures volume, not weight.
How many grams is half a cup?▾
Half a cup in grams is 60g of flour, 99g of sugar, or 114g of butter (one wrapped stick is labelled 113g). A ½ cup is simply half the ingredient's grams-per-cup value.
Is 1 cup always 250 grams?▾
No. 1 cup is only ~250g for water-like liquids. Flour is 120g, sugar is 198g, and honey is 340g per cup, the weight always depends on density.
How do I convert grams to cups without a scale?▾
Use the charts and converter on this page. Match your ingredient, find the grams amount, and read the cup measurement, no scale needed to convert grams to cups.
Why do European recipes use grams?▾
Grams are precise and repeatable, while cups vary from baker to baker. Weighing in grams gives consistent results every time, so most of the world outside the US measures baking ingredients by weight.
How do I convert 500 grams to cups?▾
500 grams to cups is about 4⅙ cups of flour or 2½ cups of sugar. Divide 500 by the ingredient's grams-per-cup value (flour 120, sugar 198) to get the exact cups.
