Frequently Asked Questions

How many cups is 800g of powdered sugar?

800 grams of powdered sugar is 6⅔ cups. In kitchen measures that is 6 cups + 10 tablespoons + 2 teaspoons, worked out from 120 grams per US cup.

How many grams are in 1 cup of powdered sugar?

One US cup of powdered sugar weighs about 120 grams, one tablespoon about 7.5 grams, and one teaspoon about 2.5 grams. This page divides 800 grams by that cup weight.

Is 800g of powdered sugar the same as 800g of all-purpose flour?

No. 800g of powdered sugar is 6⅔ cups, while 800g of all-purpose flour is 6⅜ cups. Same weight on the scale, different volume in the cup, because the two have different densities.

How do I measure 800g of powdered sugar without a scale?

Use 6 cups + 10 tablespoons + 2 teaspoons. Powdered sugar clumps and compacts in the bag. Sift or whisk it first, then spoon it into the cup — do not tap the cup down.

Is it better to weigh powdered sugar or measure it in cups?

Weighing is more accurate, especially in baking, because it removes the variation in how the powdered sugar is packed into the cup. If you have no scale, use the cup figure above and keep your measuring method consistent across the whole recipe.
