How Much Is 1 Teaspoon of Mayonnaise in Grams?

1 teaspoon of mayonnaise weighs 4.58 g. This is based on mayonnaise having a density of 220g per cup. Because teaspoons measure volume and grams 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

teaspoons × 4.58g/tsp = grams
  1. Start with 1 teaspoon of mayonnaise
  2. 1 teaspoon of mayonnaise = 4.58g
  3. 1 × 4.58 = 4.58g

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

Mental Math Shortcut

For 1 teaspoon of mayonnaise, just remember: 4.58g. Double it for 2 teaspoons (9.17g), halve it for a half teaspoon (2.29g).

Measuring Tip

For the most accurate results, weigh mayonnaise on a kitchen scale. Thick spreads can vary by 5-10% depending on how firmly they are packed.

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 a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 4.58 g, 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 teaspoons by 4.58 (grams per teaspoon for mayonnaise). For 1 teaspoon: 1 × 4.58 = 4.58 g.
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: 4.58 g ÷ 4.58 = 1 teaspoon. Or use the Grams to Teaspoons converter.
