1/3 cup to Grams: Flour, Sugar, Butter and More
1/3 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
1/3 cup equals 42g all-purpose flour, but 67g granulated sugar.
Pick the ingredient before you bake. The wrong cup-to-grams conversion can add enough flour or sugar to change the texture.
