1/2 Cup of Sugar in Grams
1/2 cup of granulated sugar weighs 100 grams (about 3.5 oz), based on 200 g per US cup (level cup). That's the same as 8 tablespoons of granulated sugar. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
1/2 cup is the measure most kitchens reach for first. Double it for a full cup (200 g), halve it for 1/4 cup (50 g) — both are standard scoops, which is why recipes lean on this one.

No 1/2 cup measure? Use spoons
1/2 cup is exactly 8 tablespoons, which is 100 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 1/2 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 | ¼ cup | 50 g | 4 tablespoons |
| As written | ½ cup | 100 g | 8 tablespoons |
| Double | 1 cup | 200 g | 16 tablespoons |
Nearby amounts
| Cups | Grams | Ounces |

| ⅓ cups | 67 g | 2.4 oz |
| ½ cups | 100 g | 3.5 oz |
| ⅔ cups | 133 g | 4.7 oz |
| ¾ cups | 150 g | 5.3 oz |

How to measure 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.
