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.
Understanding the Units
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.
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.

If you have a kitchen scale, weighing egg whites gives you an exact starting point for this conversion. If you need to measure by volume instead, pour into the measuring cup on a flat surface and read the level at eye height.
Egg sizes vary naturally, so the ounces to cups result can differ by 5-10% between individual eggs. This conversion uses large eggs as the standard. For carton egg whites, the density is very consistent.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of egg whites fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
