1 1/2 Cups of Sugar in Grams
1 1/2 cups of granulated sugar weighs 300 grams (about 10.6 oz), based on 200 g per US cup (level cup). That's the same as 24 tablespoons of granulated sugar. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
1 1/2 cups is one full cup plus a half (200 g + 100 g). At this size the fill method starts to matter: the error in each cup is added, not averaged.

No 1 1/2 cups measure? Use spoons
1 1/2 cups is exactly 24 tablespoons, which is 300 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.

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 | ¾ cup | 150 g | 12 tablespoons |
| As written | 1 ½ cups | 300 g | 24 tablespoons |
| Double | 3 cups | 600 g | 48 tablespoons |

How to measure 1 1/2 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.
