How Much Is 4.5 Cups of Brown Sugar in Ounces?
Converting 4.5 cups of brown sugar to ounces gives 34.92 oz. One cup of brown sugar weighs 220g, so 4.5 cups is 4.5 × 220 = 990g (34.92 oz). This conversion is specific to brown sugar because each ingredient has a different density.
Formula and Step-by-Step
- Start with 4.5 cups of brown sugar
- 1 cup of brown sugar = 220g
- 4.5 × 220 = 990g
- Convert grams to ounces: 990 ÷ 28.3495 = 34.92 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Light and dark brown sugar have the same density per cup (220g). The difference is molasses content, which affects flavor but not weight.

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?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
