Cups to Grams Converter
Pick an ingredient and convert cups to grams, or grams to cups. A cup of flour weighs less than a cup of sugar, so the answer depends on what you measure.
120 g
1 cup of all-purpose flour weighs 120 g (4.2 oz).
USDA lists 125 g per cup for all-purpose flour. See why the numbers differ below.
Based on King Arthur Baking’s ingredient weight chart (1 US cup, spooned and leveled). Weights vary with how you fill the cup.

Grams to cups
To turn grams into cups, divide by the weight of 1 cup: 250 g of all-purpose flour ÷ 120 g = 2.08 cups. Most results do not land on a whole cup, so the chart shows how to measure them with standard cups and spoons.
| Grams | Cups and spoons |
|---|---|
| 100 g all-purpose flour | ¾ cup + 1 tbsp + 1 tsp |
| 200 g all-purpose flour | 1⅔ cups |
| 250 g all-purpose flour | 2 cups + 1 tbsp + 1 tsp |
| 500 g all-purpose flour | 4¼ cups |
| 100 g granulated sugar | ½ cup |
| 200 g granulated sugar | 1 cup |
| 250 g granulated sugar | 1¼ cups |
| 500 g granulated sugar | 2½ cups |
| 100 g butter | 7 tbsp |
| 200 g butter | ¾ cup + 2 tbsp + ½ tsp |
| 250 g butter | 1 cup + 1 tbsp + 2 tsp |
| 500 g butter | 2¼ cups |
Why charts give different numbers
If you compare two charts, you will often see different grams for the same cup. Both can be right. The weight depends on how the cup was filled. King Arthur Baking says a cup of all-purpose flour that is fluffed, spooned and leveled holds about 120 g, but a packed cup can hold up to 160 g.
The USDA food database lists the same ingredients a little heavier, between 1% and 6% more per cup. Other converters may use either set of numbers, or their own. A difference this size rarely changes how a recipe turns out.
| Ingredient | King Arthur | USDA |
|---|---|---|
| All-purpose flour | 120 g | 125 g |
| Brown sugar, packed | 213 g | 220 g |
| Confectioners' (powdered) sugar | 113 g | 120 g |
| Granulated sugar | 198 g | 200 g |
| Butter | 226 g | 227 g |
| Cocoa powder, unsweetened | 84 g | 86 g |

How to measure flour without a scale
A kitchen scale is the most accurate. Without one, this method gets a cup of all-purpose flour close to 120 g.
- 1
Fluff the flour
Stir the flour in its bag or container with a spoon to loosen it.
- 2
Spoon it into the cup
Spoon the flour into a dry measuring cup until it overflows. Do not shake or tap the cup.
- 3
Level the top
Sweep a straight edge, like the back of a knife, across the rim to remove the extra flour.

Frequently asked questions
1 cup of all-purpose flour is 120 g when you spoon it into the cup and level it. Bread flour and cake flour are also about 120 g. Whole wheat flour is about 113 g. A cup that is scooped straight from the bag can weigh up to 160 g.
1 cup of granulated sugar is 198 g. Packed brown sugar is 213 g, and confectioners' sugar is 113 g unsifted.
1 cup of butter is 226 g, which is 2 US sticks. One stick (½ cup or 8 tablespoons) is 113 g.
A US cup holds about 237 ml. Water weighs about 1 g per ml, so a cup of water is about 237 g, and milk is almost the same. Nutrition labels round the cup to 240 ml. Some baking charts, including King Arthur’s, list 227 g (8 ounces).
100 g of all-purpose flour is about ⅚ cup: measure it as ¾ cup + 1 tbsp + 1 tsp.
Yes. Sifted flour or sugar has more air, so a cup holds less. USDA lists 1 cup of powdered sugar at 120 g unsifted and 100 g sifted.
No. A US cup is about 237 ml. Australia, New Zealand and Canada often use a 250 ml metric cup. This page uses the US cup. With a 250 ml cup, every weight here is about 6% higher.
