How Much Is 0.31 Cups of Egg Whites in Ounces?
0.31 cups of egg whites weighs 2.66 oz. This is based on egg whites having a density of 243g 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 0.31 cups.
Formula and Step-by-Step
- Start with 0.31 cups of egg whites
- 1 cup of egg whites = 243g
- 0.31 × 243 = 75.33g
- Convert grams to ounces: 75.33 ÷ 28.3495 = 2.66 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
A whole large egg without shell weighs about 50g. When separating eggs for a recipe, weigh the whites and yolks individually for the most accurate results.

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.
