How Much Is 1 Tablespoon of Mayonnaise in Ounces?
1 tablespoon of mayonnaise weighs 0.49 oz. This is based on mayonnaise having a density of 220g per cup. Because tablespoons 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 tablespoon.
Formula and Step-by-Step
- Start with 1 tablespoon of mayonnaise
- 1 tablespoon of mayonnaise = 13.75g
- 1 × 13.75 = 13.75g
- Convert grams to ounces: 13.75 ÷ 28.3495 = 0.49 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 Tablespoon?
One tablespoon holds about 15 milliliters. There are 16 tablespoons in a cup and 3 teaspoons in a tablespoon. In baking, tablespoon measurements are used for butter, oil, honey, and other ingredients where a full cup would be too much.
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.
