How to Convert Teaspoons to Tablespoons

To convert a measurement in teaspoons to a measurement in tablespoons, divide 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:

tablespoons = teaspoons ÷ 3

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

For example, here's how to convert 5 teaspoons to tablespoons using the formula above.

tablespoons = (5 tsp ÷ 3) = 1.666667 tbsp

How Many Tablespoons Are in a Teaspoon?

There is 1/3 tablespoon in a teaspoon, which is why we divide by 3 in the formula above.

1 tsp = 1/3 tbsp

You might also be wondering how many teaspoons are in a tablespoon. To find out, can multiply the value by three instead of dividing to reverse this formula.
