Formula and Step-by-Step

teaspoons × 4.58g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 90 teaspoons of brown sugar
  2. 1 teaspoon of brown sugar = 4.58g
  3. 90 × 4.58 = 412.5g
  4. Convert grams to ounces: 412.5 ÷ 28.3495 = 14.55 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.
