2/3 Cup of Milk in Grams
2/3 cup of milk (whole) weighs 163 grams (about 5.7 oz), based on 245 g per US cup (1 US cup = 240 ml). That's the same as 10.7 tablespoons of milk (whole). 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 (82 g each). Without a 1/3 measure either, 10 tablespoons + 2 teaspoons is exact.

No 2/3 cup measure? Use spoons

| Half | ⅓ cup | 82 g | 5 tablespoons + 1 teaspoon |
| As written | ⅔ cup | 163 g | 10 tablespoons + 2 teaspoons |
| Double | 1 ⅓ cups | 327 g | 21 tablespoons + 1 teaspoon |
