How Much Is 2.78 Cups of Granulated Sugar in Ounces?
2.78 cups of granulated sugar equals 19.61 oz. Granulated sugar has a density of 200g per cup (200g per cup), which means it's moderate weight compared to other common cooking ingredients. For comparison, 2.78 cups of all-purpose flour would be 12.27 oz.
Formula and Step-by-Step
- Start with 2.78 cups of granulated sugar
- 1 cup of granulated sugar = 200g
- 2.78 × 200 = 556g
- Convert grams to ounces: 556 ÷ 28.3495 = 19.61 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

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 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.
