How it works
Milliliter = Tablespoon × 14.78676. Every value is converted through a single liter base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting tablespoons to milliliters is something home cooks, bakers, and bartenders do constantly when a recipe was written for one measuring system but their kitchen tools belong to another. It also shows up when measuring liquid medicine, mixing baby formula, or following a cocktail recipe where a "tbsp" of syrup needs to land precisely in a metric jigger. Because cooking liquids by spoon is forgiving but dosing medicine is not, knowing the exact factor matters more in some situations than others.
The tablespoon is a customary unit rooted in the US measurement system, where it is legally defined as exactly half a US fluid ounce. The milliliter is its metric counterpart, defined as one-thousandth of a liter, the SI-derived unit used almost everywhere outside the United States. So this conversion is essentially a bridge between an American kitchen spoon and the metric scale that the rest of the world cooks with.
A handy rule of thumb: one US tablespoon is just shy of 15 mL, so for everyday cooking you can simply multiply by 15 and round. That gives 30 mL for 2 tbsp, 45 mL for 3 tbsp, and so on — never off by more than about one and a half percent, which is invisible in a soup or marinade. Reach for the exact 14.78676 factor only when precision genuinely counts.
The biggest pitfall is assuming all tablespoons are equal. This page uses the US tablespoon (about 14.79 mL), but the Australian tablespoon is 20 mL, the UK metric tablespoon is 15 mL, and an old imperial tablespoon was about 17.76 mL. Grabbing a recipe from the wrong country and applying the US factor can throw a measurement off by a third, so always confirm which tablespoon your source intended before you convert.

How many mL is 2 tablespoons?
Two US tablespoons equal 29.57352 mL, which conveniently rounds to about 30 mL — exactly one US fluid ounce.
Is a tablespoon exactly 15 mL?
Not in the US system; a US tablespoon is 14.78676 mL. The 15 mL value is the metric tablespoon used in the UK, Canada, and most of Europe, so the answer depends on the country.

One US tablespoon is 14.78676 mL, usually rounded to 15 mL for dosing. Always follow the exact mL stated on the medication label rather than relying on a kitchen spoon, since household spoons vary widely.
What is 3 tablespoons in milliliters?
Three US tablespoons equal 44.36028 mL, which rounds to about 45 mL using the 15 mL-per-tablespoon shortcut.
How many mL is half a tablespoon?
Half a US tablespoon is 7.39338 mL, roughly 7.5 mL, and it is equal to 1.5 teaspoons.
Why is a US tablespoon 14.79 mL and not a round number?
Because the US tablespoon is defined as exactly half a US fluid ounce, and a US fluid ounce is 29.5735 mL — a figure derived from the gallon, not from the metric system, so it does not land on a tidy round number.
Is an Australian tablespoon the same as a US tablespoon?
No. The Australian tablespoon is 20 mL, noticeably larger than the US tablespoon's 14.79 mL, so Australian recipes will measure short if you use US spoons.
