How Much Is 15 Teaspoons of Tomato Paste in Ounces?
15 teaspoons of tomato paste weighs 2.89 oz. This is based on tomato paste having a density of 262g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 15 teaspoons.
Formula and Step-by-Step
- Start with 15 teaspoons of tomato paste
- 1 teaspoon of tomato paste = 5.46g
- 15 × 5.46 = 81.88g
- Convert grams to ounces: 81.88 ÷ 28.3495 = 2.89 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Tomato paste is commonly used as a fat or egg substitute in baking. When substituting, convert by weight for accuracy.

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?
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.
