What Is the Tablespoons to Milliliters Converter?
This tool converts a volume measured in tablespoons (tbsp) into milliliters (mL). It uses the US customary tablespoon, which is defined as exactly 14.7867648 milliliters. Tablespoons are common in recipes and dosing instructions, while milliliters are the standard metric unit of volume used on most measuring cups and syringes worldwide.
How to Use It
Enter the number of tablespoons you want to convert and the calculator instantly shows the equivalent in milliliters. You can enter whole numbers or decimals (for example 1.5 tablespoons). The result is rounded for readability, but the conversion uses the full-precision factor.
The Formula Explained
The conversion is a simple multiplication:
$$\text{mL} = \text{tbsp} \times 14.7867648$$Because one US tablespoon is defined as 1/2 US fluid ounce, and one US fluid ounce equals 29.5735296 mL, half of that gives 14.7867648 mL per tablespoon. Multiply your tablespoon amount by this factor to get milliliters.
Worked Example
Suppose a recipe calls for 3 tablespoons of olive oil and you want it in milliliters. Multiply: $$3 \times 14.7867648 = 44.3602944 \text{ mL}$$ which rounds to about 44.36 mL. So 3 tablespoons is roughly 44 mL.
FAQ
