Formula and Step-by-Step

cups × 220g/cup ÷ 28.3495g/oz = ounces
  1. Start with 2.5 cups of brown sugar
  2. 1 cup of brown sugar = 220g
  3. 2.5 × 220 = 550g
  4. Convert grams to ounces: 550 ÷ 28.3495 = 19.40 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Brown sugar should always be firmly packed into the measuring cup. Loosely measured brown sugar can weigh 15-20% less than packed.

Understanding the Units

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
