US Tablespoon vs Millilitre: which is bigger?
A us tablespoon is the larger unit: one us tablespoon equals 14.78676 millilitres. Put another way, you need 14.78676 millilitres to make a single us tablespoon.
What is a US Tablespoon? History, origin and usage
The tablespoon entered measurement in the 18th century as an unofficial apothecaries' unit equal to half a fluid ounce, or four drams, and that relationship survives in the modern US customary tablespoon. It grew out of the actual serving spoon used at the table.
The tablespoon is a universal cooking measure for oils, sauces, sugar, butter and spices, and three teaspoons make one tablespoon. It is one of the few customary units used routinely even in metric kitchens.
Tablespoon sizes are not the same worldwide: the US, UK and Canada use a tablespoon of roughly 15 millilitres, but the Australian tablespoon is 20 millilitres, equal to four teaspoons rather than three. This can quietly throw off a recipe carried across borders.
What is a Millilitre? History, origin and usage
The millilitre is the litre scaled by the metric prefix milli- (Latin mille, a thousandth), so it inherits the litre's origin in the 1795 French metric reforms. Because the litre was defined in relation to the metre, the millilitre became exactly one cubic centimetre when the litre was tied to the cubic decimetre. It has been part of the coherent metric vocabulary ever since the SI prefixes were standardised.
The millilitre is the workhorse small-volume unit almost everywhere outside the United States: medicine doses, syringes and IV bags, drink and food nutrition labels, perfume and cosmetics, and home cooking. Laboratories and pharmacies use it constantly for measuring liquids. In medicine the equivalent term cubic centimetre (cc) is still heard, especially for syringes.
One millilitre is identical in volume to one cubic centimetre, because a litre is exactly one cubic decimetre. A standard metric teaspoon is taken as five millilitres, which is why liquid-medicine dosing cups are graduated in millilitres rather than spoons.

- Both fields update live as you type — change either side to convert in that direction.
How to use this US Tablespoon to Millilitre converter
Type a number into the US Tablespoon field and the equivalent in Millilitre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Millilitre field to convert the other way (millilitre to us tablespoon). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 tbsp = 14.78676 mL), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for us tablespoon-to-millilitre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
