Formula and Step-by-Step

teaspoons × 4.58g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 109.09 teaspoons of mayonnaise
  2. 1 teaspoon of mayonnaise = 4.58g
  3. 109.09 × 4.58 = 500.00g
  4. Convert grams to ounces: 500.00 ÷ 28.3495 = 17.64 oz

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

Understanding the Units

What is a Teaspoon?

A US teaspoon is 4.929 ml, a metric teaspoon is exactly 5 ml, and an imperial teaspoon is 5.919 ml. The metric and US versions are nearly identical (1.4% difference), but the imperial teaspoon is 20% larger. For most spices the difference is negligible, but for leaveners like baking powder it can affect the result.

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 17.64 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 teaspoons by 4.58 (grams per teaspoon for mayonnaise), then divide by 28.3495 to convert grams to ounces. For 109.09 teaspoons: 109.09 × 4.58 = 500.00g, then 500.00 ÷ 28.3495 = 17.64 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.
