How Much Is 3 Cups of Couscous in Ounces?
3 cups of couscous weighs 18.31 oz. This is based on couscous having a density of 173g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 3 cups.
Formula and Step-by-Step
- Start with 3 cups of couscous
- 1 cup of couscous = 173g
- 3 × 173 = 519g
- Convert grams to ounces: 519 ÷ 28.3495 = 18.31 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Uncooked and cooked grains have completely different weights per cup. These conversions are for uncooked/dry grains unless specified otherwise.

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?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.
