A tablespoon is usually about 15 milliliters in cooking measurements, which is 3 teaspoons or about 1/2 US fluid ounce.

Quick scoop

If you mean the measuring spoon , that’s the standard size most recipes use. In the U.S. and metric cooking, it’s commonly rounded to 15 mL.

A small note

The utensil itself can vary a lot in size, so a regular eating spoon is not always the same as a measuring tablespoon. If you’re following a recipe, a marked measuring spoon is the safest choice.

If you want, I can also tell you how to measure a tablespoon without a spoon set.
