3 Cups of Flour in Grams
3 cups of all-purpose flour weighs 360 grams (about 12.7 oz), based on 120 g per US cup (spoon-and-level method). That's the same as 48 tablespoons of all-purpose flour. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
3 cups is batch territory — a cup-measuring error is multiplied three times over, which for all-purpose flour is the difference between 360 g and something noticeably off. Weigh it if you can.

No 3 cups measure? Use spoons
3 cups is exactly 48 tablespoons, which is 360 g of all-purpose flour. Measuring spoons are stamped to a tighter tolerance than cups, so for small amounts the spoon route is usually the more accurate one even when you do own the cup.
Halving and doubling 3 cups
Scaling a recipe is the usual reason this conversion comes up, and grams scale cleanly where cup fractions do not:
| Recipe | Cups | Grams | Spoons |
|---|---|---|---|
| Half | 1 ½ cups | 180 g | 24 tablespoons |
| As written | 3 cups | 360 g | 48 tablespoons |
| Double | 6 cups | 720 g | 96 tablespoons |

How to measure 3 cup of all-purpose flour
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.
