Cup & Gram

1 1/2 Cups of Rice in Grams

1 1/2 cups of uncooked white rice weighs 278 grams (about 9.8 oz), based on 185 g per US cup (level cup). That's the same as 24 tablespoons of uncooked white rice. 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 (185 g + 93 g). At this size the fill method starts to matter: the error in each cup is added, not averaged.
