How to use the tablespoons to milliliters converter
- Enter a number in the Tablespoons field to convert tbsp to ml, or enter a number in the Milliliters field to convert the other way.
- The result updates automatically as you type.
- Use the converted value directly in your recipe or measurement notes.
How the conversion works
The United States defines one tablespoon as exactly half a US fluid ounce. Since one US fluid ounce equals 29.5735295625 milliliters, one US tablespoon is exactly 14.78676478125 ml.
To convert tablespoons to milliliters, multiply by that factor:
ml = tbsp x 14.78676478125
For example, 3 tablespoons: 3 x 14.78676478125 = 44.3603 ml.
To go from milliliters back to tablespoons, divide instead:
tbsp = ml / 14.78676478125
Common tablespoon to milliliter values
This table lists frequently used amounts for quick reference when scaling recipes.
| Tablespoons (US) | Milliliters |
|---|---|
| 0.5 | 7.3934 |
| 1 | 14.7868 |
| 2 | 29.5735 |
| 3 | 44.3603 |
| 4 | 59.1471 |
| 8 (half cup) | 118.2941 |
| 16 (one cup) | 236.5882 |
Values are rounded to four decimal places. For everyday cooking, rounding to one or two decimals is usually sufficient.
US, metric and imperial tablespoons
Not every tablespoon is the same size. The US tablespoon used in this converter is about 14.79 ml. A metric tablespoon, used in Australia, New Zealand and many European countries, is defined as exactly 15 ml. The difference is small but can add up in large batches.
The UK imperial tablespoon is approximately 17.76 ml, though modern British recipes typically use the 15 ml metric tablespoon. If you are following an older British cookbook, check which standard it assumes before converting.
This tool strictly uses the US tablespoon. If your recipe calls for metric tablespoons, simply multiply by 15 instead.
Practical tips for measuring liquids
When measuring viscous liquids like honey or syrup, coat the spoon lightly with oil so the ingredient slides out completely. Otherwise you will leave behind a significant amount and your conversion from tbsp to ml will be off in practice even if the math is correct.
For dry ingredients, level the spoon with a straight edge rather than heaping it. A heaped tablespoon can hold nearly double the volume of a level one, making any conversion unreliable.
If you need to measure fractions of a tablespoon, consider using a smaller unit. One tablespoon equals three teaspoons, so half a tablespoon is 1.5 teaspoons. You can also use the teaspoons to ml converter for finer precision, or the cups to ml converter for larger volumes.
Why milliliters are preferred in baking
Professional bakers often weigh ingredients in grams, but when volume measurements are necessary, milliliters offer more precision than tablespoons. A standard set of measuring spoons might only include quarter, half and full tablespoons, forcing you to estimate odd amounts.
A graduated cylinder or a syringe marked in milliliters lets you measure exactly 22 ml without having to figure out what fraction of a tablespoon that represents. Converting tbsp to ml bridges the gap between traditional spoon-based recipes and precise metric tools.

FAQ
How many ml is 1 tablespoon?
One US tablespoon equals exactly 14.78676478125 milliliters. In most recipes this is rounded to 15 ml for convenience, but the exact value matters for precise work.
Is a tablespoon 15 ml or 20 ml?
A US tablespoon is about 14.79 ml, commonly rounded to 15 ml. An Australian metric tablespoon is exactly 15 ml. No standard tablespoon is 20 ml, though some older regional definitions varied.
How do I convert tablespoons to milliliters?
Multiply the number of tablespoons by 14.78676478125. For example, 2 tablespoons times 14.78676478125 equals 29.5735 ml.
Does this converter work for dry ingredients?
This tool converts volume units. Dry ingredients have different densities, so one tablespoon of flour weighs less than one tablespoon of sugar. The volume conversion remains the same regardless of the ingredient.
What is the difference between a tablespoon and a teaspoon?
One tablespoon equals three teaspoons. A US teaspoon is about 4.93 ml. You can use the tsp to ml converter for teaspoon measurements.
Are UK and US tablespoons the same?
No. The traditional UK imperial tablespoon is about 17.76 ml, while the US tablespoon is about 14.79 ml. Modern UK recipes generally use the 15 ml metric tablespoon.
