100 g of Egg Whites Equals How Many Cups? – Simple Kitchen Measurement Guide

When a recipe calls for a specific weight of egg whites—like 100 grams—but you only have measuring cups at home, it can be confusing. Don’t worry! In this article, we’ll break down the conversion step-by-step so you can confidently measure your egg whites without messing up your recipe.

Understanding Egg White Measurements

Egg whites can be measured in different ways—by weight (grams or ounces) or by volume (cups or tablespoons). Professional bakers often prefer weight for accuracy, but most home cooks rely on cups or spoons.

So, the main question is: How much cup volume does 100 grams of egg whites take up?

Basic Weight-to-Volume Conversion

• 1 large egg white weighs approximately 33–35 grams.
• 100 grams of egg whites is roughly equal to 3 large egg whites.
• In terms of cups, 1 large egg white equals about 2 tablespoons or 1/8 cup.

This means:

100 grams of egg whites ≈ 6 tablespoons ≈ 0.375 cup (about 3/8 cup).

Step-by-Step Conversion

Let’s understand this step by step so you can apply the same logic to other measurements:

1. Find out the weight of a single egg white (average: 33 g).
2. Divide 100 g by 33 g to find how many egg whites you need (~3 egg whites).
3. Convert egg whites to cup measurement: 1 egg white ≈ 1/8 cup, so 3 egg whites ≈ 3/8 cup.

So, you can use a measuring cup and fill it just under the half-cup mark (between 1/3 and 1/2 cup) to get close to 100 grams of egg whites.

Why Accuracy Matters in Egg White Measurement

Egg whites are used in recipes for structure, texture, and stability—especially in meringues, soufflés, and angel food cakes. If you add too much or too little, you might change the consistency of your recipe.

For example:

• In baking: Too much egg white can make a cake dry and rubbery.
• In meringues: Too little egg white will result in flat, weak peaks.
• In omelets or scrambles: The texture changes, and you lose the desired fluffiness.

Quick Kitchen Tip:

If the recipe is delicate, use a kitchen scale to measure exactly 100 grams of egg whites. But if you’re cooking something flexible like scrambled eggs, using 3/8 cup is perfectly fine.

Real-Life Example

Let’s say you are making a pavlova and the recipe says “100 g of egg whites.” You open your fridge and have no scale. Here’s what you can do:

1. Crack and separate the eggs, keeping only the whites.
2. Measure the liquid whites in a measuring cup—aim for about 3/8 cup.
3. This will give you approximately the same amount as 100 grams.

It’s like measuring sugar: You may know 1 cup is about 200 grams, so 100 grams is half a cup. With egg whites, you use the same principle but with a smaller volume.

Conversion Table for Egg Whites

Key Takeaways

• 100 grams of egg whites is approximately 3 large egg whites.
• That equals around 3/8 cup or 6 tablespoons.
• Use a kitchen scale for precise baking, or measure by cups for everyday cooking.

💡 Final Thought

Cooking and baking are part science, part art. Knowing how to convert 100 g of egg whites into cups saves you from second-guessing in the kitchen. Remember—3/8 cup is your magic number! And if you’re aiming for perfection in delicate recipes, grab a digital kitchen scale to make sure your measurements are spot-on.
