This cups to grams converter turns cups, tablespoons and teaspoons into grams, ounces and pounds, and back again, for more than 90 common ingredients. Pick the ingredient first, because a cup of all-purpose flour weighs 120 grams while a cup of honey weighs 336 grams. The result updates as you type, and a quick chart shows the most-used cup measures for the ingredient you chose.

Result
120 grams
1 cup of all-purpose flour weighs 120 grams.
Based on 120 g per cup. Source: King Arthur Baking ingredient weight chart, spooned and leveled.
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20% or more.
All-purpose flour: cups to grams
| Cups | Grams | Ounces |
|---|---|---|
| ¼ cup | 30 g | 1 oz |
| ⅓ cup | 40 g | 1½ oz |
| ½ cup | 60 g | 2 oz |
| ⅔ cup | 80 g | 2¾ oz |
| ¾ cup | 90 g | 3¼ oz |
| 1 cup | 120 g | 4¼ oz |
Why cups to grams depends on the ingredient
A cup measures volume: how much space an ingredient takes up. Grams measure weight. Light, airy ingredients like flour and powdered sugar weigh much less per cup than dense ones like honey, butter or sugar. That is why there is no single answer to “how many grams in a cup”.
- 1 cup of all-purpose flour: 120 g
- 1 cup of granulated sugar: 198 g
- 1 cup of butter: 227 g
- 1 cup of water: 237 g
- 1 cup of honey: 336 g
How to measure ingredients by volume
The weights in this converter assume standard US measuring cups and spoons, filled the way most American recipes expect.
Flour and other dry ingredients
Stir the flour to loosen it, spoon it into the measuring cup until it mounds over the top, then sweep a knife across to level it. Scooping straight from the bag packs the flour and can add 20% or more, which leads to dry cakes and tough cookies.
Brown sugar
Press brown sugar firmly into the cup until it holds its shape when you tip it out. The brown sugar weight in this converter is for packed sugar.
Liquids
Use a clear liquid measuring cup with a spout. Set it on the counter and read the line at eye level.
Sticky ingredients
Lightly oil the cup before measuring honey, molasses, maple syrup or peanut butter so it slides out cleanly and you get the full amount.
US cups, tablespoons and teaspoons
- 1 cup = 16 tablespoons = 48 teaspoons = 236.6 milliliters
- ½ cup = 8 tablespoons
- ¼ cup = 4 tablespoons
- 1 tablespoon = 3 teaspoons = 14.8 milliliters
- 1 stick of butter = ½ cup = 8 tablespoons = 114 grams
Volume conversions such as cups to tablespoons or cups to milliliters are the same for every ingredient. Only conversions between volume and weight need the ingredient.
Grams, ounces and pounds
1 ounce equals 28.35 grams and 1 pound equals 16 ounces, or 453.6 grams. Do not confuse ounces with fluid ounces: a measuring cup holds 8 fluid ounces of anything, but 1 cup of all-purpose flour weighs only about 4¼ ounces.
Why bakers weigh ingredients
- You get the same result every time, no matter who measures.
- You can measure straight into the mixing bowl, so there are fewer cups to wash.
- Scaling a recipe up or down is simple multiplication.
- Recipes from Europe and many professional bakers list grams, so a scale lets you follow them exactly.
