How to Convert Teaspoons to Tablespoons

To convert teaspoons to tablespoons, multiply the volume by the following conversion ratio: 0.3333333 tablespoons/teaspoon.

Since one teaspoon is equal to 0.3333333 tablespoons, you can use this simple formula to convert:

tablespoons = teaspoons × 0.3333333

The volume in tablespoons is equal to the volume in teaspoons multiplied by 0.3333333.

For example, here's how to convert 6 teaspoons to tablespoons using the formula above.

tablespoons = (6 tsp × 0.3333333) = 2 tbsp

How Many Tablespoons Are in a Teaspoon?

There are 0.3333333 tablespoons in a teaspoon, which is why we use this value in the formula above.

1 tsp = 0.3333333 tbsp|1 tbsp = 3 tsp

Our teaspoon to tablespoon calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Teaspoons and tablespoons are both units used to measure volume. Keep reading to learn more about each unit.

What Is a Teaspoon?

A teaspoon is a unit of volume equal to 0.0049289 liters (L), the base unit for volume. 1/3 of a US tablespoon (4.9289 mL). [1]

The teaspoon is classified as a US customary unit of volume. Teaspoons can be abbreviated as tsp; for example, 1 teaspoon can be written as 1 tsp.

When working with teaspoons (tsp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, teaspoons (tsp) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within US customary workflows, engineering documentation, and technical data sheets.

What Is a Tablespoon?

A tablespoon is a unit of volume equal to 0.0147868 liters (L), the base unit for volume. 1/2 US fluid ounce or 3 US teaspoons (14.7868 mL). [2]

The tablespoon is classified as a US customary unit of volume. Tablespoons can be abbreviated as tbsp; for example, 1 tablespoon can be written as 1 tbsp.

When working with tablespoons (tbsp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, tablespoons (tbsp) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.

When converting volume between teaspoons (tsp) and tablespoons (tbsp), keep full floating-point precision (1 tsp = 0.3333333 tbsp; 1 tbsp = 3 tsp) during intermediate calculations and round only the final tablespoon figure to match your instrument tolerance.
