About Sugar
Granulated sugar is the standard sweetener in baking. One US cup weighs approximately 200 grams, the classic reference conversion for sugar.
Whether you are scaling a recipe up, substituting an ingredient, or converting a recipe from metric to US measurements, having an accurate grams-per-cup value for sugar removes the guesswork from your cooking. Bookmark this page for quick reference whenever sugar appears in a recipe.
How much does a cup of sugar weigh?
A standard US cup of sugar weighs about 200 grams (7.05 ounces). That makes it about 1.7 times heavier than a cup of all-purpose flour, and about the same weight as a cup of granulated sugar (200 g). This is why a converter that uses the same factor for every ingredient will give wrong answers: sugar has its own density, and recipes depend on it.

Values are reference weights for level, unpacked measures unless the ingredient is normally packed. Brand, moisture, temperature and how firmly you fill the cup can shift the result by a few percent, so for precision baking weigh sugar on a kitchen scale and use the cup figure only as a guide. To understand why these numbers differ between ingredients, read our guide on why a cup of flour is not a cup of sugar, or see why weighing beats measuring cups.
