Measuring Tip
One large egg white weighs approximately 30g and one large egg yolk weighs approximately 17g. Weighing separated eggs is more reliable than counting, since individual eggs vary in size.
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?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

The most accurate way is to weigh egg whites on a kitchen scale, since individual eggs vary in size. If you are measuring by volume, pour into the measuring cup on a flat surface and read the level at eye height. Egg whites are liquid and settle naturally, so volume measurements are reasonably consistent.
Egg sizes vary naturally, so the cups to grams 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.
Weighing is more consistent than volume measuring. A cup of egg whites can vary by 10-20% depending on how it's scooped, packed, or leveled. Weighing gives the same result every time, which is especially important in baking where precision affects texture and rise.
