2/3 cup to Grams: Flour, Sugar, Butter and More

2/3 cup to grams changes by ingredient. A cup of flour is not a cup of sugar by weight, so this chart gives the numbers recipe snippets usually flatten.

Quick answer

2/3 cup equals 83g all-purpose flour, but 133g granulated sugar.

Pick the ingredient before you bake. The wrong cup-to-grams conversion can add enough flour or sugar to change the texture.

Frequently Asked Questions

2/3 cup is a different gram weight for each ingredient. For example, 2/3 cup all-purpose flour is 83g, while 2/3 cup granulated sugar is 133g.

A cup is a volume measure. Grams measure weight. Dense ingredients weigh more per cup than light or aerated ingredients.

Grams are more accurate. If a recipe gives cups, use the ingredient-specific chart and a consistent measuring method such as Spoon & Level.
