Formula and Step-by-Step

tablespoons × 13.75g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 12 tablespoons of mayonnaise
  2. 1 tablespoon of mayonnaise = 13.75g
  3. 12 × 13.75 = 165g
  4. Convert grams to ounces: 165 ÷ 28.3495 = 5.82 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Mayonnaise weighs 220g per cup. Low-fat and regular mayonnaise have slightly different densities.

Understanding the Units

What is a Tablespoon?

A tablespoon is roughly the volume of a large soup spoon. In precise terms, 1 US tablespoon equals 14.787 ml, which is very close to the 15 ml metric standard used in most of the world. Three teaspoons make one tablespoon.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 5.82 oz, based on mayonnaise having a density of 220g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of tablespoons by 13.75 (grams per tablespoon for mayonnaise), then divide by 28.3495 to convert grams to ounces. For 12 tablespoons: 12 × 13.75 = 165g, then 165 ÷ 28.3495 = 5.82 oz.
For the most accurate results, weigh mayonnaise on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
Reverse the conversion: 5.82 oz × 28.3495 = 165g, then 165g ÷ 13.75 = 12 tablespoons. Or use the Ounces to Tablespoons converter.
