How Much Is 2 Cups of Egg Whites in Grams?
2 cups of egg whites equals 486.00 g. Egg whites has a density of 243g per cup (243g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 2 cups of all-purpose flour would be 250.32 g.
Formula and Step-by-Step
- Start with 2 cups of egg whites
- 1 cup of egg whites = 243g
- 2 × 243 = 486g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
Quick check: 2 cups is just double the single-cup weight. 1 cup = 243g, so 2 = 486g.
Measuring Tip
Carton egg whites and yolks have very consistent density, making them easier to measure by volume than freshly separated eggs. If your recipe calls for a specific gram amount, carton products are the most predictable.
Egg Whites at Different Amounts

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 a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
