120 grams to cups
120 grams in cups depends entirely on the ingredient.
120 grams is a common baking quantity, but it converts to a different number of cups for every ingredient because each one has its own density. Use the chart and calculator below to see 120 g in cups for flour, sugar, butter, cocoa and more.

120 grams to cups by ingredient
| Ingredient | 120 g in cups | Decimal |
|---|---|---|
| All-purpose flour | 1 cup | 1 |
| Bread flour | 1 cup | 1 |
| Cake flour | 1.05 cups | 1.05 |
| Almond flour | 1¼ cups | 1.25 |
| Granulated sugar | 0.6 cup | 0.6 |
| Packed brown sugar | 0.55 cup | 0.55 |
| Powdered sugar | 1 cup | 1 |
| Butter | ½ cup | 0.53 |
| Cocoa powder | 1.41 cups | 1.41 |
| Rolled oats | 1⅓ cups | 1.33 |
| Honey | ⅓ cup | 0.35 |
| Milk | ½ cup | 0.49 |
| Vegetable oil | 0.55 cup | 0.55 |
One hundred twenty grams is a benchmark amount because it happens to equal almost exactly one US cup of all-purpose flour, the most-converted ingredient in baking. That tidy coincidence makes it easy to forget how differently other ingredients behave at the same weight. While 120 g of flour (about 120 g per cup) is essentially 1 cup, 120 g of granulated sugar (about 200 g per cup) is only about 0.6 cup, noticeably less volume for identical weight. Airy cocoa powder (about 85 g per cup) balloons 120 g to roughly 1.4 cups, and packed brown sugar (about 220 g per cup) settles to about 0.55 cup. The flour-equals-one-cup shortcut is genuinely useful, but applying it to denser sugars or lighter cocoa will throw a recipe off. Weigh each ingredient on its own terms.
Cups measure volume and grams measure weight, so there is no single grams-to-cups number, always pick the ingredient. Choose it in the calculator above to switch cup sizes too.
