How Much Is 4.5 Cups of Granulated Sugar in Grams?
4.5 cups of granulated sugar weighs 900.00 g. This is based on granulated sugar having a density of 200g per cup. Because cups measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 4.5 cups.
Formula and Step-by-Step
- Start with 4.5 cups of granulated sugar
- 1 cup of granulated sugar = 200g
- 4.5 × 200 = 900g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Granulated sugar weighs 200g per cup. Different sugar types have different densities, so always use the specific type your recipe calls for.
Granulated Sugar at Different Amounts
How granulated sugar scales across common cups measurements. Your amount (4.5 cups) is highlighted.
For reference, 4.5 cups of granulated sugar (900g) is close in weight to a 2 lb bag of sugar (907g).

Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Gram?
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
