Formula and Step-by-Step

cups × 243g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1.98 cups of egg whites
  2. 1 cup of egg whites = 243g
  3. 1.98 × 243 = 481.14g
  4. Convert grams to ounces: 481.14 ÷ 28.3495 = 16.97 oz

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.

Frequently Asked Questions

About 16.97 oz, 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.
Multiply the number of cups by 243 (grams per cup for egg whites), then divide by 28.3495 to convert grams to ounces. For 1.98 cups: 1.98 × 243 = 481.14g, then 481.14 ÷ 28.3495 = 16.97 oz.
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: 16.97 oz × 28.3495 = 481.14g, then 481.14g ÷ 243 = 1.98 cups. Or use the Ounces to Cups converter.
