Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 243g/cup = cups
  1. Start with 10 ounces of egg whites
  2. Convert ounces to grams: 10 × 28.35 = 283.50g
  3. 1 cup of egg whites = 243g
  4. 283.50g ÷ 243g/cup = 1.17 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

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?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

What is a Cup?

The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.

Frequently Asked Questions

About 1.17 cups, based on egg whites having a density of 243g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 243 (grams per cup). For 10 ounces: 10 × 28.3495 = 283.50g, then 283.50 ÷ 243 = 1.17 cups.
The most accurate way is to weigh egg whites on a kitchen scale, since individual eggs vary in size. If measuring by volume, pour into the measuring cup and read the level at eye height.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 1.17 cups × 243g/cup = 283.50g, then 283.50g ÷ 28.3495 = 10 ounces. Or use the Cups to Ounces converter.
