How many cups is 100 grams?
It depends on the ingredient, because a gram measures weight and a cup measures volume. 100 g of all-purpose flour is about ¾ cup plus 1 tablespoon, 100 g of granulated sugar is ½ cup and 100 g of butter is about ¼ cup plus 3 tablespoons.
This chart gives the gram amounts metric recipes use most, in US cups of 236.6 ml.
| Ingredient | 100 g | 200 g | 250 g | 500 g |
|---|---|---|---|---|
| All-purpose flour | ¾ cup + 1 tbsp | 1 ⅔ cups | 2 cups + 1 tbsp | 4 ¼ cups |
| Bread flour | ¾ cup + 1 tbsp | 1 ⅔ cups | 2 cups + 1 tbsp | 4 ¼ cups |
| Granulated sugar | ½ cup | 1 cup | 1 ¼ cups | 2 ½ cups |
| Brown sugar (packed) | ½ cup | ¾ cup + 3 tbsp | 1 cup + 3 tbsp | 2 ⅓ cups |
| Powdered sugar (unsifted) | ¾ cup + 2 tbsp | 1 ¾ cups | 2 ¼ cups | 4 ½ cups |
| Butter | ¼ cup + 3 tbsp | ¾ cup + 2 tbsp | 1 cup + 2 tbsp | 2 ¼ cups |
| Rolled oats | 1 cup + 2 tbsp | 2 ¼ cups | 2 ¾ cups + 1 tbsp | 5 ⅔ cups |
| Rice (uncooked) | ½ cup | 1 cup | 1 ¼ cups | 2 ½ cups |

Why grams rarely land on a clean cup
Metric recipes are written in round weights, and a round weight is seldom a round volume. 250 g of flour is 2.08 cups, which no measuring set has. The converter shows the exact figure in the field and, on the line under it, the nearest amount you can measure: 2 cups plus 1 tablespoon. The difference is a few grams, well inside what a recipe tolerates.
If you bake often from metric recipes, a kitchen scale is the better tool: it is exact, and there is one bowl to wash instead of four cups.
Cups to grams
The converter works both ways. Type the cups in the first field and read the grams in the second.
| Ingredient | ¼ cup | ⅓ cup | ½ cup | 1 cup |
|---|---|---|---|---|
| All-purpose flour | 30 g | 40 g | 60 g | 120 g |
| Bread flour | 30 g | 40 g | 60 g | 120 g |
| Granulated sugar | 50 g | 66 g | 99 g | 198 g |
| Brown sugar (packed) | 53 g | 71 g | 107 g | 213 g |
| Powdered sugar (unsifted) | 28 g | 38 g | 57 g | 113 g |
| Butter | 57 g | 76 g | 113 g | 227 g |
| Rolled oats | 22 g | 30 g | 45 g | 89 g |
| Rice (uncooked) | 50 g | 66 g | 99 g | 198 g |
US cups and metric cups
A US cup holds 236.6 ml. In Australia, New Zealand and Canada a cup holds 250 ml, about 6 percent more. If your measuring cups are metric, choose metric cups in the unit list: 250 g of all-purpose flour is then just under 2 metric cups instead of just over 2 US cups.
Where the weights come from
The weights of flours, sugars, fats, nuts and other baking ingredients come from King Arthur Baking’s ingredient weight chart. The weights of water, milk, cream, yogurt, oils, cooked white rice and pasta come from USDA FoodData Central. Both were checked in November 2026. The converter covers 103 ingredients.
