2 Cups of Oats in Grams
2 cups of rolled oats weighs 178 grams (about 6.3 oz), based on 89 g per US cup (level cup). That's the same as 32 tablespoons of rolled oats. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
2 cups is a US pint by volume. Cup-measuring it doubles whatever error one cup carries, so if you own a scale this is the point where it starts to pay.

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 cup | 89 g | 16 tablespoons |
| As written | 2 cups | 178 g | 32 tablespoons |
| Double | 4 cups | 356 g | 64 tablespoons |
