Cups to Grams Converter

A cups to grams converter turns a volume measurement into the matching weight, based on the ingredient's density, the reverse of converting grams to cups.

Tip: Pick your ingredient first: grams per cup depend on density, not just volume.

How to Use This Cups to Grams Converter

Accurate conversions come from ingredient density, not a single fixed formula.

Choose the Exact Ingredient

Select the specific ingredient variety, since flour, sugar, and butter each convert differently from the same cup amount.

Enter the Cup Amount

Type the amount from your recipe, including fractions like 0.33 for 1/3 cup or 0.5 for 1/2 cup.

Read the Gram Result

The calculator shows the exact weight in grams, plus ounces, pounds, and kilograms at the same time.

Weigh and Bake

Weigh the gram result directly on a kitchen scale, for the same accuracy a professional bakery relies on.

US Cups vs. Metric Cups

This converter uses the US cup, which holds 236.6 ml. A metric cup, common in Australia and parts of Europe, holds 250 ml, about 5.7% more. Check your recipe's country of origin before assuming which cup it means.

When This Page Is Most Useful

Use this page when a recipe lists cups but you want to weigh ingredients instead, when you're scaling a recipe up or down and want to stay precise, or when you're converting a recipe for a scale-only kitchen.

Why Cups to Grams Conversions Change by Ingredient

Flour Is the Most Variable Cups to Grams Ingredient

A cup of flour can weigh anywhere from 105 to 145 grams depending on technique alone, before any difference in flour type is considered.

Spoon-and-Level

120g per cup

Spoon flour into the cup, then level with a straight edge. This site's reference value.

Sifted First

≈ 105–115g per cup

Sifting adds air before measuring, lowering the weight in the same cup.

Scooped or Packed

≈ 140–150g per cup

Scooping straight from the bag compacts flour, adding 20 to 30 grams.

Sugar Changes by Crystal Size and Packing

Sugar type changes the cup weight by up to 83%, from powdered sugar to packed brown sugar.

Granulated Sugar

200g per cup

Powdered Sugar

120g per cup

Brown Sugar (Packed)

220g per cup

Butter and Dairy Liquids Are Close, But Not Identical

Butter, water, milk, and half-and-half all fall within 15 grams of each other per cup.

Butter

227g

Water

236.6g

Milk

240g

Half-and-Half

242g

Oats and Alternative Flours Stay Light by Volume

Ingredients with more air between particles weigh less per cup, even when they feel substantial by volume.

Rolled Oats

90g per cup

Almond Flour

96g per cup

Coconut Flour

112g per cup

Why Accuracy Matters in Baking

Ingredient Brand

Brand and grind size shift an ingredient's density by a small amount. Flour density commonly ranges from 115 to 130 grams per cup between brands.

Measuring Method

Spooning, scooping, and sifting each pack a different amount of the same ingredient into the same cup, a swing of 15% to 20% for flour.

Cup Standard

A US cup, a metric cup, and a UK cup hold different volumes, a spread of nearly 20% between the smallest and largest.

Practical Tips

Weigh ingredients directly whenever a recipe lists grams. Spoon and level dry ingredients instead of scooping. Match your cup standard to the recipe's country of origin, and weigh flour for any recipe where structure matters, such as bread or laminated dough.

Cups to Grams FAQ

How many grams are in a cup of flour?

One cup of all-purpose flour is 120 grams. Other flours differ: bread flour is 127 grams per cup, and almond flour is 96 grams per cup.

How many grams are in a cup of sugar?

One cup of granulated sugar is 200 grams. Packed brown sugar is heavier at 220 grams per cup, and powdered sugar is 120 grams per cup.

How many grams are in a cup of butter?

One cup of butter is 227 grams, or 2 standard US sticks.

Is 1 cup always 200 grams?

No, 1 cup is not always 200 grams. That figure only applies to granulated sugar. A cup of flour is 120 grams and a cup of honey is 340 grams, since each ingredient has its own density.

How do I convert cups to grams without a scale?

Convert cups to grams without a scale by using an ingredient-specific converter, such as the calculator on this page, then measure the resulting weight with a scale if one becomes available, or continue measuring by cup with confidence in the equivalent weight.

Why do 1 cup of different grains weigh different amounts?

Density, not volume, sets the weight. A cup of rolled oats weighs 90 grams while a cup of rice weighs 185 grams, since oats trap far more air between the flakes.

How many grams is 1/2 cup of butter?

1/2 cup of butter is 113.5 grams, half of the 227 grams in a full cup.

Is baking by cups accurate enough for bread?

No, baking bread by cups is not accurate enough for consistent results. Bread recipes depend on a precise flour-to-water ratio, and a 10% cup-measuring error changes the dough's hydration enough to affect rise and texture.

Can I convert cups to grams for liquids the same way?

Yes, liquids convert the same way as dry ingredients, using that liquid's own grams-per-cup value. Water weighs 236.6 grams per cup and milk weighs 240 grams per cup, close but not identical.

Why is a packed cup heavier than a level cup?

Pressing an ingredient down removes air pockets, fitting more mass into the same volume. Packed brown sugar weighs 220 grams per cup versus about 180 grams loose.
