Formula and Step-by-Step

cups × 243g/cup = grams
  1. Start with 0.3 cups of egg whites
  2. 1 cup of egg whites = 243g
  3. 0.3 × 243 = 72.9g

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 a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 72.90 g, 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). For 0.3 cups: 0.3 × 243 = 72.90 g.
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: 72.90 g ÷ 243 = 0.3 cups. Or use the Grams to Cups converter.
