Formula and Step-by-Step

teaspoons × 4.58g/tsp = grams
  1. Start with 12 teaspoons of mayonnaise
  2. 1 teaspoon of mayonnaise = 4.58g
  3. 12 × 4.58 = 55g

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 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 a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 55.00 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 12 teaspoons: 12 × 4.58 = 55.00 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: 55.00 g ÷ 4.58 = 12 teaspoons. Or use the Grams to Teaspoons converter.
