Formula and Step-by-Step

(pounds × 453.59g/lb) ÷ 243g/cup = cups
  1. Start with 0.81 pounds of egg whites
  2. Convert pounds to grams: 0.81 × 453.59 = 367.41g
  3. 1 cup of egg whites = 243g
  4. 367.41g ÷ 243g/cup = 1.51 cups

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

Measuring Tip

A whole large egg without shell weighs about 50g. When separating eggs for a recipe, weigh the whites and yolks individually for the most accurate results.

Frequently Asked Questions

About 1.51 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 pounds to grams (1 pound = 453.592g), then divide by 243 (grams per cup). For 0.81 pounds: 0.81 × 453.592 = 367.41g, then 367.41 ÷ 243 = 1.51 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: 1.51 cups × 243g/cup = 367.41g, then 367.41g ÷ 453.592 = 0.81 pounds. Or use the Cups to Pounds converter.
