1/3 Cup of Sugar in Grams
1/3 cup of granulated sugar weighs 67 grams (about 2.4 oz), based on 200 g per US cup (level cup). That's the same as 5.3 tablespoons of granulated sugar. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
1/3 cup is the awkward fraction: it does not divide into whole tablespoons, and halving it lands on 2 tablespoons + 2 teaspoons. Two scoops make 2/3 cup (133 g), three make a full cup (200 g).

No 1/3 cup measure? Use spoons
1/3 cup is exactly 5 tablespoons + 1 teaspoon, which is 67 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 1/3 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 | ⅛ cup | 33 g | 2 tablespoons + 2 teaspoons |
| As written | ⅓ cup | 67 g | 5 tablespoons + 1 teaspoon |
| Double | ⅔ cup | 133 g | 10 tablespoons + 2 teaspoons |

How to measure 1/3 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.
