Formula and Step-by-Step

cups × 120g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1.89 cups of powdered sugar
  2. 1 cup of powdered sugar = 120g
  3. 1.89 × 120 = 226.8g
  4. Convert grams to ounces: 226.8 ÷ 28.3495 = 8.00 oz

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

Measuring Tip

Powdered sugar clumps easily. Sift before measuring by volume, or weigh to avoid the sifted-vs-unsifted ambiguity entirely.

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.

Frequently Asked Questions

About 8.00 oz, based on powdered sugar having a density of 120g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 120 (grams per cup for powdered sugar), then divide by 28.3495 to convert grams to ounces. For 1.89 cups: 1.89 × 120 = 226.8g, then 226.8 ÷ 28.3495 = 8.00 oz.
For the most accurate results, weigh powdered sugar on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Granulated and powdered sugars should be spooned into the measuring cup and leveled off. Do not pack them unless the recipe specifically says to.
Reverse the conversion: 8.00 oz × 28.3495 = 226.8g, then 226.8g ÷ 120 = 1.89 cups. Or use the Ounces to Cups converter.
