How to convert cups to grams for granulated sugar

Ingredient conversion is a two-step calculation. First, cups are turned into grams using granulated sugar's density of about 200 g per cup, or its exact weight factor for cups. Then those grams are expressed in grams. Because every conversion passes through weight, the result is consistent whether you start from cups, tablespoons, milliliters, or ounces.

Density is the reason a universal "cups to grams" number does not exist. A cup of sifted all-purpose flour is about 120 g, while a cup of granulated sugar is about 200 g and a cup of honey about 340 g. Using one ingredient's density for another is the most common cause of dry cakes and dense breads, so always confirm the ingredient selected above matches what is in your bowl.

For the most repeatable results, weigh granulated sugar on a digital scale instead of relying on volume. If you are scaling a whole recipe, use the recipe scaler to multiply every ingredient at once, then verify individual amounts with this converter.

Frequently asked questions

How many grams is a cup of granulated sugar?

One US cup of granulated sugar weighs about 200 grams (7.05 oz). That density is what this converter uses, so volume and weight results stay consistent for every measurement on the page.

How many grams is 1 cup of granulated sugar?

1 cup of granulated sugar equals about 200 g (200 g), or 200 grams. Use the converter above for any other amount.

Why does granulated sugar convert differently from other ingredients?

Weight-to-volume conversions depend on ingredient density. A cup of granulated sugar weighs about 200 g, while a cup of granulated sugar weighs about 200 g and a cup of water 237 g. That is why a single "cups to grams" number cannot apply to every ingredient.

Are these Cups to Grams conversions exact?

They use standard average densities for granulated sugar (about 200 g per cup). Actual weight varies with how the ingredient is packed, sifted, or ground, so weigh on a digital scale when a recipe is sensitive to hydration or leavening.
