2/3 Cup of Rice in Grams
2/3 cup of uncooked white rice weighs 123 grams (about 4.3 oz), based on 185 g per US cup (level cup). That's the same as 10.7 tablespoons of uncooked white rice. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
Few measuring sets include a 2/3 cup, so this is normally 2 × 1/3 cup (62 g each). Without a 1/3 measure either, 10 tablespoons + 2 teaspoons is exact.

No 2/3 cup measure? Use spoons

| As written | ⅔ cup | 123 g | 10 tablespoons + 2 teaspoons |
