How to use
- Pick the ingredient.
- Choose USDA, or King Arthur if your recipe comes from their kitchen.
- Read the grams in 2/3 cup, or use two level 1/3 cup scoops.
The formula and two worked examples
2/3 cup = 16 × 2 ÷ 3 = 10 2/3 tablespoons = 10 tbsp + 2 tsp and grams in 2/3 cup = grams per cup × 2 ÷ 3
Why 2 teaspoons: 2/3 of a tablespoon is 2 teaspoons, because a tablespoon holds 3. So 2/3 cup is 10 tablespoons with 2 teaspoons left over.
Whole milk. 244 g per cup × 2 ÷ 3 = 162.7 g, shown as 163 g. That matches what the cups to grams converter gives for 2/3 cup.
How to measure 2/3 cup without a 2/3 cup measure
No 2/3 cup? Use any of these:
- Two level 1/3 cup scoops. The easiest swap.
- 1/2 cup plus 2 tablespoons plus 2 teaspoons.
- 10 level tablespoons plus 2 level teaspoons.
- For liquids, a little above the 5 fl oz line on a measuring cup (2/3 cup is 5.33 fl oz).
- Not 2 1/2 quarter cups. Two 1/4 cups plus 2 tablespoons and 2 teaspoons is right, because 2/3 cup is 2 2/3 quarter cups.
What this tool doesn't cover
It covers US measures only. A UK or Australian 2/3 metric cup is about 166.7 mL, a bit more than the US 157.7 mL. Weights assume level, spooned measures and typical US products, so packing and brands change them a little.
