Egg Whites: Grams to Cups
1 cup of egg whites = 243 grams
One US cup of egg whites weighs 243 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 257 grams. To convert any weight, divide the grams by the figure for your cup.
A cup of raw egg whites weighs 243 g (USDA FoodData Central, egg white, raw, fresh). One large egg white is 33 g, so a cup takes 7 to 8 large whites. Egg whites are mostly water, which is why the figure sits close to a cup of water or milk. Pour them into a liquid measuring cup, or weigh them, which is easier when whites are thick and stringy.

How to measure egg whites accurately
The 243 g figure assumes the spooned-and-levelled method: spoon the egg whites into a dry measuring cup and sweep the top flat with a straight edge. Scooping the cup through the bag compacts it and gives a heavier cup.

- ¾ cup = 182 g
