How Much Is 3 Cups of Brown Sugar in Ounces?
3 cups of brown sugar equals 23.28 oz. Brown sugar has a density of 220g per cup (220g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 3 cups of all-purpose flour would be 13.24 oz.
Formula and Step-by-Step
- Start with 3 cups of brown sugar
- 1 cup of brown sugar = 220g
- 3 × 220 = 660g
- Convert grams to ounces: 660 ÷ 28.3495 = 23.28 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
If your brown sugar has hardened, microwave it with a damp paper towel for 20 seconds. Hard brown sugar is still the same weight but impossible to measure by volume.
