How Much Is 1 Teaspoon of Egg Whites in Ounces?
1 teaspoon of egg whites weighs 0.18 oz. This is based on egg whites having a density of 243g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1 teaspoon.
Formula and Step-by-Step
- Start with 1 teaspoon of egg whites
- 1 teaspoon of egg whites = 5.06g
- 1 × 5.06 = 5.06g
- Convert grams to ounces: 5.06 ÷ 28.3495 = 0.18 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
One large egg white weighs approximately 30g and one large egg yolk weighs approximately 17g. Weighing separated eggs is more reliable than counting, since individual eggs vary in size.

Understanding the Units
What is a Teaspoon?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
