3 Cups of Sugar in Grams
3 cups of granulated sugar weighs 600 grams (about 21.2 oz), based on 200 g per US cup (level cup). That's the same as 48 tablespoons of granulated sugar. 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 granulated sugar is the difference between 600 g and something noticeably off. Weigh it if you can.

No 3 cups measure? Use spoons
3 cups is exactly 48 tablespoons, which is 600 g of granulated sugar. 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 | 300 g | 24 tablespoons |
| As written | 3 cups | 600 g | 48 tablespoons |
| Double | 6 cups | 1200 g | 96 tablespoons |

How to measure 3 cup of granulated sugar
Granulated sugar flows evenly, so scoop-and-level is fine — it settles to nearly the same weight however you fill the cup. That makes sugar the most forgiving ingredient to measure by volume; a level cup is 200 g within a gram or two.
