Grams to Cups Chart for Flour, Sugar, Butter and More

By Dr. Ahmed Mortuza Saleque · Updated November 10, 2026 · How we check our content

The short answer

There is no single grams-to-cups number, because a cup measures volume and grams measure weight. One U.S. cup holds about 120 g of all-purpose flour, 200 g of granulated sugar or 227 g of butter. To convert, divide the grams by the ingredient's weight per cup: 250 g of flour is about 2.1 cups, but 250 g of sugar is 1.25 cups.

Weight of one cup of common ingredients

U.S. cup (237 ml), spooned and levelled for dry ingredients. Brands and humidity shift these by a few grams.

Ingredient	1 cup	1/2 cup	1/4 cup	1 tablespoon
All-purpose flour	120 g	60 g	30 g	7.5 g
Granulated sugar	200 g	100 g	50 g	12.5 g
Brown sugar, packed	220 g	110 g	55 g	14 g
Powdered sugar	120 g	60 g	30 g	7.5 g
Butter	227 g	113 g	57 g	14 g
Rolled oats	90 g	45 g	23 g	5.6 g
Cocoa powder	85 g	43 g	21 g	5.3 g
Uncooked white rice	185 g	93 g	46 g	11.6 g
Honey	340 g	170 g	85 g	21 g

Grams to cups for round amounts

Grams	Flour	Sugar	Butter	Honey
50 g	0.42 cup	0.25 cup	0.22 cup	0.15 cup
100 g	0.83 cup	0.5 cup	0.44 cup	0.29 cup
250 g	2.08 cups	1.25 cups	1.1 cups	0.74 cup
500 g	4.17 cups	2.5 cups	2.2 cups	1.47 cups
1 kg	8.33 cups	5 cups	4.4 cups	2.94 cups

Why the same grams fill different cups

Density is the reason. Honey is heavy for its volume, so a cup of it weighs almost four times as much as a cup of oats. Flour is the trickiest ingredient: scooping the cup straight into the bag packs it down and can add 20 to 30 g per cup, enough to make a cake dry.

Recipes written in grams avoid the problem, which is why bakers prefer a scale. When a recipe only gives cups, spoon the flour into the cup and level it with a knife to get close to 120 g.

U.S. cups, metric cups and UK cups

A U.S. cup is 236.6 ml. A metric cup, used in Australia, Canada and New Zealand, is 250 ml, about 6% bigger. Older British recipes may use an imperial cup of 284 ml. If a recipe comes from another country, check which cup it means, or convert volumes with the cooking converter.

Butter: sticks, cups and grams

In the United States, butter is sold in sticks. One stick is 1/2 cup, 8 tablespoons or 113 g, so 1 cup of butter is 2 sticks or 227 g. European blocks are usually 250 g, a little more than a U.S. cup. The butter calculator converts between sticks, cups, tablespoons and grams.

Common questions

How many cups is 100 grams?

It depends on the ingredient: about 0.83 cup of flour, 0.5 cup of sugar or 0.44 cup of butter. Divide 100 by the weight of one cup of that ingredient.

How many grams are in a cup of flour?

About 120 g for all-purpose flour that is spooned into the cup and levelled. Scooped straight from the bag, it can reach 140 to 150 g.

How many cups is 250 g of sugar?

1.25 cups of granulated sugar, since one cup weighs 200 g.

Is it better to measure by weight or by cups?

Weight is more reliable, especially for flour. A kitchen scale gives the same amount every time, while a cup changes with how tightly the ingredient is packed.
