## How Much Is a Teaspoon?

The teaspoon is a unit of volume equal to 1/3 of a tablespoon or 1/6 of a fluid ounce.[1] One teaspoon is equal to approximately 4.929 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.[2]

## How to Convert Teaspoons

To convert teaspoons to another unit of volume, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[3]

You can find the conversion factors for teaspoons in the conversion table below.

Then, multiply the volume measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

teaspoons × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
