How to Convert Tablespoons to Milliliters
To convert tablespoons to milliliters, multiply the volume by the following conversion ratio: 14.7867648 milliliters/tablespoon.
Since one tablespoon is equal to 14.7867648 milliliters, you can use this simple formula to convert:
The volume in milliliters is equal to the volume in tablespoons multiplied by 14.7867648.
For example, here's how to convert 2 tablespoons to milliliters using the formula above.
How Many Milliliters Are in a Tablespoon?
There are 14.7867648 milliliters in a tablespoon, which is why we use this value in the formula above.
Our tablespoon to milliliter calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Tablespoons and milliliters are both units used to measure volume. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Milliliter?
A milliliter is a unit of volume equal to 1/1,000 of a liter (0.001 L). One-thousandth of a liter, identical to 1 cubic centimeter (cc). [2]
The milliliter is classified as a metric and SI-compatible unit of volume. Milliliters can be abbreviated as mL; for example, 1 milliliter can be written as 1 mL.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliliter (mL) a convenient decimal multiple of the liter (L).
In practice, milliliters (mL) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting volume between tablespoons (tbsp) and milliliters (mL), keep full floating-point precision (1 tbsp = 14.7867648 mL; 1 mL = 0.067628 tbsp) during intermediate calculations and round only the final milliliter figure to match your instrument tolerance.
