100 Grams to Cups: Flour, Sugar, Butter, Oats, Milk and Honey
100 grams is about 3/4 cup plus 1 tablespoon of all-purpose flour (0.83 cup), exactly 1/2 cup of granulated sugar, and roughly 7 tablespoons of butter (0.44 cup). The answer changes by ingredient because a gram measures weight and a cup measures volume. For any other weight, use our full grams to cups converter.
100 Grams to Cups by Ingredient
| Ingredient | Grams per cup | 100 g in cups | Kitchen measure |
|---|---|---|---|
| All-purpose flour | 120 g | 0.83 cup | 3/4 cup + 1 tbsp |
| Granulated sugar | 200 g | 0.50 cup | 1/2 cup |
| Packed brown sugar | 220 g | 0.45 cup | 1/4 cup + 3 tbsp |
| Powdered sugar | 120 g | 0.83 cup | 3/4 cup + 1 tbsp |
| Butter | 227 g | 0.44 cup | 1/4 cup + 3 tbsp |
| Rolled oats | 90 g | 1.11 cup | 1 cup + 2 tbsp |

Values use a US customary cup. Kitchen measures are rounded to the nearest tablespoon, and ingredient weights follow the standard spoon-and-level method. Brands, humidity and packing can shift a real cup by 5 to 10 percent, so weigh when precision matters.
How to Convert 100 Grams to Cups
Divide 100 by the grams-per-cup weight of your ingredient. Flour at 120 g per cup gives 100 ÷ 120 = 0.83 cup. Sugar at 200 g per cup gives 100 ÷ 200 = 0.50 cup. To convert grams to cups for a different weight or ingredient, use the converter on our homepage.
Why 100 g Is Different Cup Amounts
Flour and powdered sugar are light and full of air, so 100 g fills most of a cup. Granulated sugar, butter and honey are denser, so the same 100 g fills half a cup or less. Oats are the lightest here, so 100 g is slightly more than one full cup.
