How Much Is 1 Teaspoon of Mayonnaise in Ounces?
1 teaspoon of mayonnaise weighs 0.16 oz. This is based on mayonnaise having a density of 220g 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 mayonnaise
- 1 teaspoon of mayonnaise = 4.58g
- 1 × 4.58 = 4.58g
- Convert grams to ounces: 4.58 ÷ 28.3495 = 0.16 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Mayonnaise should be spooned into the measuring spoon and leveled off. Do not scoop directly from the jar, which traps air.

Understanding the Units
What is a Teaspoon?
One teaspoon holds about 5 milliliters. There are 3 teaspoons in a tablespoon and 48 teaspoons in a cup. Teaspoon accuracy matters most with leaveners like baking powder and baking soda, where small differences affect rise and texture.
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
