100 Grams of Flour to Cups
100 grams of all-purpose flour equals ⅞ cup (0.83 US cups), based on 120 g per cup (spoon-and-level method). In the kitchen, measure 13 tbsp. For best results, weigh all-purpose flour with a scale — cup measurements vary with how the cup is filled.
| US cups | ⅞ cup (0.83 cups) |
|---|---|
| Measured as | 13 tbsp |
| Ounces (weight) | 3.5 oz |
| Tablespoons (level) | about 13.3 tbsp |
| Density used | 120 g per US cup |
Seeing a different answer elsewhere? Sources disagree on flour: King Arthur's spoon-and-level standard is 120 g per cup (our number, giving ⅞ cup), while USDA-based tables use 125 g (giving ¾ cup, 0.8 cups). Both are correct for their measuring method — see how we measure.
How to measure 100 g of all-purpose flour without a scale
Spoon flour into the cup with a spoon, then level the top with a straight edge — never scoop the cup into the bag. Scooping compresses flour and can pack in 20–30% more (140 g+ instead of 120 g), which is the single most common reason baked goods turn out dry. Sifted flour runs lighter still, about 110 g per cup.

100 grams of other ingredients
The same weight fills a very different cup depending on density — that's why "grams to cups" always needs the ingredient:
- 100 g of granulated sugar to cups — ½ cup
- 100 g of powdered sugar to cups — ⅞ cup
- 100 g of brown sugar (packed) to cups — ½ cup
- 100 g of honey to cups — ⅓ cup
- 100 g of butter to cups — ½ cup
