1/2 Cup of Brown Sugar in Grams
1/2 cup of brown sugar (packed) weighs 107 grams (about 3.8 oz), based on 213 g per US cup (packed into the cup). That's the same as 8 tablespoons of brown sugar (packed). 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 (213 g), halve it for 1/4 cup (53 g) — both are standard scoops, which is why recipes lean on this one.

No 1/2 cup measure? Use spoons

|---|---|---|---|
| Half | ¼ cup | 53 g | 4 tablespoons |
