1 cup of flour is about 120 grams, 1 cup of sugar is 200 grams, and 1 cup of butter is 227 grams. To convert cups to grams, multiply the cups by the ingredient's grams-per-cup weight. Use the reverse converter below for any amount.

How much 1 cup weighs for common baking and cooking ingredients. Multiply these by your number of cups to convert.
| Ingredient | 1 cup in grams |

| All-Purpose Flour | 120 g |
| Granulated Sugar | 200 g |
| Brown Sugar (Packed) | 220 g |
| Butter | 227 g |
| Powdered Sugar | 120 g |
| Water / Milk | 237 g |
| Oats (Rolled) | 80 g |
| White Rice | 185 g |
| Chocolate Chips | 160 g |
| Honey | 340 g |
| Almonds (Whole) | 140 g |
| Cocoa Powder | 100 g |
| Salt | 292 g |
| Baking Powder | 192 g |
| Vegetable Oil | 224 g |
A cup is a measure of volume, while grams measure weight, so the conversion depends on how heavy the ingredient is. To convert, multiply the number of cups by the ingredient's grams-per-cup weight. For example, 2 cups of flour is 2 × 120 = 240 grams, while 2 cups of honey is 2 × 340 = 680 grams.
This is why you can't use one fixed number for everything: a cup of a light ingredient like flour or oats weighs far less than a cup of a dense one like honey or salt. For baking, weighing in grams is always more accurate than measuring by the cup.
One cup of all-purpose flour is about 120 grams when spooned and leveled. Scooping directly can pack it to around 140 grams.
One cup of granulated sugar is about 200 grams. Packed brown sugar is heavier at around 220 grams, and powdered sugar is lighter at about 120 grams.
One cup of butter is about 227 grams, which equals 2 US sticks.
One cup of water or milk is about 237 grams, since water weighs almost exactly 1 gram per millilitre.
Because a cup measures volume while grams measure weight. Each ingredient has a different density, so the same cup of a light ingredient like flour weighs far less than a cup of a dense one like honey.
