How many grams are in a cup?
It depends on what is in the cup. A cup measures volume and a gram measures weight, so a cup of all-purpose flour weighs 120 g, a cup of granulated sugar 198 g and a cup of honey 336 g. That is why the converter asks for the ingredient first.
This chart gives the ingredients people convert most. The weights are for a US cup of 236.6 ml.

Why a cup of flour is 120 g here and 125 g or more elsewhere
Flour packs down, so the weight of a cup depends on how it was filled. King Arthur Baking weighs a cup of all-purpose flour at 120 g, measured by spooning the flour into the cup and leveling it with a knife. The USDA lists 125 g. A cup dipped straight into the bag holds more again. All of these are honest measurements of different habits, which is why charts disagree.
This converter uses King Arthur Baking’s ingredient weight chart for baking ingredients and USDA FoodData Central for liquids and dairy, and the line under the fields names the source of the number you are looking at. If the author of your recipe gives their own weight for a cup of flour, use theirs.
Grams to cups
Type the grams in the second field and the converter works backwards. When the answer is not a clean measure, it tells you what to reach for.
| Ingredient | 100 g | 250 g | 500 g |
|---|---|---|---|
| All-purpose flour | ¾ cup + 1 tbsp | 2 cups + 1 tbsp | 4 ¼ cups |
| Granulated sugar | ½ cup | 1 ¼ cups | 2 ½ cups |
| Brown sugar (packed) | ½ cup | 1 cup + 3 tbsp | 2 ⅓ cups |
| Powdered sugar (unsifted) | ¾ cup + 2 tbsp | 2 ¼ cups | 4 ½ cups |
| Butter | ¼ cup + 3 tbsp | 1 cup + 2 tbsp | 2 ¼ cups |
| Rolled oats | 1 cup + 2 tbsp | 2 ¾ cups + 1 tbsp | 5 ⅔ cups |
| Rice (uncooked) | ½ cup | 1 ¼ cups | 2 ½ cups |
| Honey | ¼ cup + 2 tsp | ¾ cup | 1 ½ cups |
US cups, metric cups and UK cups
A US cup holds 236.6 ml. The metric cup used in Australia, New Zealand and Canada holds 250 ml, about 6 percent more, so a metric cup of all-purpose flour weighs 127 g instead of 120 g. To convert a recipe written with metric cups, choose metric cups in the unit list. Recipes from the United Kingdom are usually written in grams already, and the old imperial cup of 284 ml is rare.
How to fill a cup so the weight is right
Flour, cocoa and powdered sugar: stir it, spoon it into the cup and level the top with a knife. Do not shake or tap the cup.
Brown sugar: press it into the cup until it holds its shape when you turn it out.
Liquids: use a liquid measuring cup on a flat surface and read it at eye level.
Honey, syrup and peanut butter: oil the cup lightly first and they slide out clean.
Teaspoons and tablespoons in grams
The converter also takes teaspoons, tablespoons, fluid ounces, milliliters, ounces and pounds. These are the small amounts people look up most.
| Ingredient | 1 teaspoon | 1 tablespoon |
|---|---|---|
| Granulated sugar | 4 g | 12 g |
| Table salt | 6 g | 18 g |
| Butter | 4.5 g | 14 g |
| All-purpose flour | 2.5 g | 8 g |
| Baking powder | 4 g | 12 g |
| Baking soda | 6 g | 18 g |
| Instant yeast | 3 g | 9 g |
| Honey | 7 g | 21 g |
| Olive oil | 4.5 g | 14 g |
| Cocoa powder | 1.8 g | 5 g |
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, and each answer shows which of the two sources it rests on.
