How to use this calculator

  1. Choose the ingredient: flour, sugar and butter weigh very different amounts per cup.
  2. Enter the weight in grams.
  3. Read the volume in cups, tablespoons and teaspoons, based on the King Arthur Baking chart.

Why there is no single grams-to-cups number

Grams measure weight and cups measure volume, so the answer depends on density: a cup of all-purpose flour is about 120 g, while a cup of granulated sugar is about 198 g.
