To convert a measurement in tablespoons to a measurement in teaspoons, multiply the volume by the following conversion ratio: 3 teaspoons/tablespoon.

Since one tablespoon is equal to 3 teaspoons, you can use this simple formula to convert:

teaspoons = tablespoons × 3

The volume in teaspoons is equal to the volume in tablespoons multiplied by 3.

For example, here's how to convert 5 tablespoons to teaspoons using the formula above.
teaspoons = (5 tbsp × 3) = 15 tsp

How Many Teaspoons Are in a Tablespoon?

There are 3 teaspoons in a tablespoon, which is why we use this value in the formula above.

1 tbsp = 3 tsp

For fractional tablespoons, such as finding how many teaspoons are in 1/2 tablespoon, you'll need to multiply the fraction by 3 to convert the measurement. If you have a fraction of a tablespoon, multiplying it by 3 gives you the equivalent volume in teaspoons.
