The Formula
Common Tablespoons to Milliliters Values
| Tablespoons | Milliliters | Fraction |
|---|---|---|
| 0.25 | 3.70 | 3⅔ |

| 0.75 | 11.09 | 11⅛ |
| 1 | 14.79 | 14¾ |
| 1.5 | 22.18 | 22⅛ |
| 2 | 29.57 | 29⅝ |
| 3 | 44.36 | 44⅜ |
| 4 | 59.15 | 59⅛ |
| 5 | 73.94 | 73⅞ |
| 8 | 118.30 | 118⅓ |
| 10 | 147.87 | 147⅞ |
| 12 | 177.44 | 177½ |
A Worked Example
A cocktail recipe calls for 2.5 tablespoons of simple syrup. Multiply 2.5 by 14.787 to get about 37ml — a figure that matches directly to a milliliter-marked cocktail measuring tool if a tablespoon isn't handy.
When This Conversion Matters
A US tablespoon is 14.79ml, a fixed volume conversion used constantly in international recipe conversions.
This is especially useful for measuring liquid ingredients like oil, vanilla extract, or vinegar in small amounts.
Medicine dosing charts and over-the-counter product labels frequently list both tablespoon and milliliter amounts, since consumers may only have a kitchen spoon rather than a dosing syringe on hand.
Coffee, cocktail, and skincare recipes that originated outside the US often use milliliters natively, requiring this conversion to translate an ingredient list into US kitchen-spoon measurements.
Recipe apps that let users toggle between US and metric units typically store the underlying data in milliliters and convert to tablespoons on the fly, using the same 14.787ml factor referenced throughout this page.
Standards and Sources
The US tablespoon is fixed at 14.787 milliliters (often rounded to 14.79ml) under NIST measurement standards — exactly 1/16 of the 236.588ml US cup.
The Australian tablespoon, at 20ml, is notably larger — about 35% more volume than the US standard — a frequent source of conversion error when following Australian recipes with US spoons.
The UK tablespoon, at 15ml under some conventions (and sometimes cited as 17.7ml in older sources), sits close to but not identical with the US figure, so checking a recipe's country of origin matters for precision.
The World Health Organization's oral rehydration solution guidelines specify precise milliliter measurements rather than spoon measurements specifically because household spoon volumes vary too much for medical-grade accuracy.
Where This Unit Comes From
The tablespoon's US volume (14.79ml) was formalized as an exact fraction of the US cup, while countries that adopted the metric system more fully, like Australia, defined their tablespoon as a round metric figure (20ml) instead.
Where This Shows Up
Coffee brewing guides that specify grounds or water by volume sometimes use milliliters even in otherwise tablespoon-based US recipes, requiring quick conversion for home baristas dialing in a precise ratio.
Skincare and DIY personal care recipes, such as a homemade face mask or hair treatment, frequently specify small liquid amounts in milliliters that a home cook needs to translate into a measurable tablespoon quantity.
Homemade cough syrup, tincture, and herbal remedy recipes shared in metric-using online communities frequently need translating from milliliters into tablespoons for US-based home preparers.
Perfume and cologne blending guides shared by hobbyist communities frequently specify carrier oil ratios in milliliters, requiring conversion for enthusiasts working with US-standard measuring spoons.
Common Mistakes
- Using the Australian 20ml tablespoon figure for a US recipe, which overstates the liquid volume by roughly 35%.
- Confusing a heaping tablespoon with a level one, introducing inconsistent extra volume into the converted ml figure.
- Forgetting that oils and syrups measure differently than powders by tablespoon, even though the ml-to-tablespoon ratio itself stays fixed.
- Assuming a plastic promotional or novelty spoon matches the standard tablespoon volume, since these are rarely calibrated to an exact measurement.
Tablespoon Size by Country
| Country/Standard | Volume | |
|---|---|---|
| United States | US customary | 14.79 ml |
| United Kingdom | Metric-based | ~15 ml |
| Australia | Metric-based | 20 ml |

Frequently Asked Questions
How many ml are in a tablespoon?+
14.79ml, for a standard US tablespoon.
Is an Australian tablespoon the same size?+
No. Australian tablespoons are 20ml, larger than the US 14.79ml standard.
How many ml are in 2 tablespoons?+
About 29.6ml.
Why is the Australian tablespoon so much larger?+
Australia standardized its tablespoon at 20ml (four times its 5ml teaspoon) rather than adopting the US ratio of three teaspoons per tablespoon, which is why the two countries' measuring spoons aren't interchangeable.
Why does this conversion matter for coffee brewing?+
Many brewing guides specify water or coffee grounds by volume, and converting to ml helps match a recipe to a scale or graduated brewing vessel.
Is a metric tablespoon the same as a US tablespoon?+
There's no single 'metric tablespoon' standard — different countries define their own, which is why checking a recipe's origin matters.
Why do some recipes list tablespoons in decimals instead of fractions?+
Decimal notation is common in recipes converted from metric sources, where a clean ml figure doesn't always translate to a tidy spoon fraction.
