Formula and Step-by-Step

cups × 220g/cup ÷ 28.3495g/oz = ounces
  1. Start with 10.31 cups of brown sugar
  2. 1 cup of brown sugar = 220g
  3. 10.31 × 220 = 2,268.2g
  4. Convert grams to ounces: 2,268.2 ÷ 28.3495 = 80.01 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.

Frequently Asked Questions

About 80.01 oz, based on brown sugar having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 220 (grams per cup for brown sugar), then divide by 28.3495 to convert grams to ounces. For 10.31 cups: 10.31 × 220 = 2,268.2g, then 2,268.2 ÷ 28.3495 = 80.01 oz.
For the most accurate results, weigh brown sugar on a kitchen scale. If measuring by volume, pack it firmly into the measuring cup and level it off. This conversion assumes packed brown sugar, which is the standard method.
Brown sugar should be firmly packed into the measuring cup. This is the standard method and what this conversion assumes. Loosely measured brown sugar will weigh significantly less.
