Formula and Step-by-Step

cups × 200g/cup ÷ 28.3495g/oz = ounces
  1. Start with 3.99 cups of raw sugar
  2. 1 cup of raw sugar = 200g
  3. 3.99 × 200 = 798g
  4. Convert grams to ounces: 798 ÷ 28.3495 = 28.15 oz

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

Understanding the Units

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 28.15 oz, based on raw sugar having a density of 200g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 200 (grams per cup for raw sugar), then divide by 28.3495 to convert grams to ounces. For 3.99 cups: 3.99 × 200 = 798g, then 798 ÷ 28.3495 = 28.15 oz.
For the most accurate results, weigh raw 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: 28.15 oz × 28.3495 = 798g, then 798g ÷ 200 = 3.99 cups. Or use the Ounces to Cups converter.
