How Much Is 2.5 Cups of Granulated Sugar in Ounces?
2.5 cups of granulated sugar weighs 17.64 oz. This is based on granulated sugar having a density of 200g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 2.5 cups.
Formula and Step-by-Step
- Start with 2.5 cups of granulated sugar
- 1 cup of granulated sugar = 200g
- 2.5 × 200 = 500g
- Convert grams to ounces: 500 ÷ 28.3495 = 17.64 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Granulated sugar should be spooned into the measuring cup and leveled off. Do not pack it unless the recipe specifically says to (packing is only standard for brown sugar).
Granulated Sugar at Different Amounts
How granulated sugar scales across common cups measurements. Your amount (2.5 cups) is highlighted.
For reference, 2.5 cups of granulated sugar (500g) is close in weight to a bottle of water (500 ml) (510g).

Understanding the Units
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
