How Much Is 128 Teaspoons of Brown Sugar in Ounces?
128 teaspoons of brown sugar weighs 20.69 oz. This is based on brown sugar having a density of 220g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 128 teaspoons.
Formula and Step-by-Step
- Start with 128 teaspoons of brown sugar
- 1 teaspoon of brown sugar = 4.58g
- 128 × 4.58 = 586.67g
- Convert grams to ounces: 586.67 ÷ 28.3495 = 20.69 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.
