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 |

So 1 cup to grams has no single value, 1 cup flour in grams is 120g, but 1 cup sugar in grams is 200g. And 1/4 cup to grams is 30g of flour or 50g of sugar, while half a cup in grams is 60g of flour or 100g of sugar.
What Is a Cup? (US vs Metric vs UK)
A cup is a unit of volume, but not all cups are equal, and this is where most conversions go wrong:
- 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.
So 1 cup in grams shifts slightly depending on which cup your recipe means. All charts on this page use the US customary cup (236.6 ml) unless noted.
What Is a Gram?
A gram is a unit of weight in the metric system, one-thousandth of a kilogram. Unlike a cup, a gram never changes: 100 grams of flour and 100 grams of lead both weigh exactly 100 grams.
That reliability is why professional bakers weigh their ingredients, and why converting grams to cups always depends on knowing the ingredient's density.
Cups = Grams ÷ (Density × 236.6)The core grams to cups formula
To convert grams to cups yourself, use this formula:
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 ÷ 200 = 0.5 cups
Butter: 227g ÷ 227 = 1 cup
Honey: 340g ÷ 340 = 1 cup
Once you know the grams-per-cup value for an ingredient, every grams to cups conversion is simple division.
Cups are convenient, but they're inconsistent. Professional bakers and culinary schools worldwide prefer grams for compelling reasons:
1
Eliminates human error in scooping
One baker's "1 cup of flour" can weigh 120g to 150g depending on scoop vs spoon, a 25% swing. 100g is 100g, period.
2
Unaffected by humidity and settling
Flour settles during shipping; gram measurements don't care. Your recipe stays consistent year-round.
3
Faster and less cleanup
No nested measuring cups to wash, weigh straight into one bowl with the tare button.
4
Easy recipe scaling
Double 250g = 500g. Simple math, try doubling 1⅔ cups in your head.
5
Universal language for global recipes
Grams work in Tokyo, Paris and Texas, share recipes internationally without conversion headaches.
6
Professional standard in every kitchen
Culinary schools and nutrition labels use grams. Learning grams now means thinking like a pro.

Master these pro baker secrets for perfect conversions every time:
Spoon & Level Flour
Spoon flour into the cup and level with a knife. Scooping packs in up to 30% extra.
Sift When Specified
Sift powdered sugar and cocoa before measuring to remove lumps and get true volume.
Pack Brown Sugar
Press brown sugar firmly into the cup, it should hold the cup's shape when tipped out.
Use the Right Cup
A US cup (236.6 ml) is not a metric cup (250 ml). Always check which cup your recipe assumes.
When in Doubt, Weigh
A kitchen scale beats any grams to cups conversion for precision, invest in 0.1g accuracy.
Zero Between Ingredients
Use the tare/zero function between each ingredient for clean, accurate measuring in one bowl.

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, 0.5 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, 227g milk. There's no single answer because a cup measures volume, not weight.
How many grams is half a cup?▾

Is 1 cup always 250 grams?▾
No. 1 cup is only ~250g for water-like liquids. Flour is 120g, sugar is 200g, 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 200) to get the exact cups.
