1 tablespoon = 14.7868 millilitres. Cups, spoons, pints and litres are all measures of the same thing — volume — and this page converts between two of them. The factor is fixed by definition, not measured in a kitchen, so it is the same for every ingredient, every recipe and every brand of measuring cup. What follows is the full table for the amounts you actually cook with, worked examples from real recipes, and the mistakes that catch people out even when the maths is right.
The reason this conversion is worth a page of its own is that it sits at the junction of two measuring traditions. The US customary system grew out of old English measures, while the metric system was designed to be decimal — and recipes cross between them constantly now that cooks follow recipes from every country on the internet. Knowing that 1 tablespoon is a fixed number of millilitres means you can follow any recipe, whatever system it was written in, with the tools you already own.

Read the table in either direction. Going from tablespoons to millilitres, multiply by 14.7868; going back, divide by 14.7868 or multiply by 0.0676. The middle rows are the ones recipes use most — 4 tablespoons is 59.1471 millilitres, and 8 tablespoons is 118.2941 millilitres. If your amount is not in the table, multiply it by 14.7868 and you have the answer. For a quick check: 1 tablespoon is 14.7868 millilitres, 2 tablespoons are 29.5735 millilitres, and 10 tablespoons are 147.8676 millilitres.
Worked examples
Checking a measuring jug. Jugs are not always honest. Pour 3 tablespoons of water into the jug — that should read 44.3603 millilitres on the millilitres scale. If it reads noticeably more or less, trust the tablespoons: measuring cups and spoons are made to a standard, while cheap jugs are often printed a few percent out. A jug that is wrong by 5% will put 5% too much liquid in every cake, soup and sauce you make with it, which is enough to notice.
Working from a video recipe. The cook on screen measures 3 tablespoons and your set only has a millilitre measure. That is 44.3603 millilitres — pause the video, count them out, and carry on. Video recipes are the worst for mixed units, because the cook never stops to convert for you. Keep this page open on your phone while you cook and the pause button becomes your conversion chart.
A recipe written in the other system. You find a tomato soup recipe from a metric cookbook that lists 177.4412 millilitres, but your measuring cups are marked in tablespoons. That is 12 tablespoons — a familiar measure again. This is the most common reason people look this conversion up mid-cook: one recipe, two measuring systems, and dinner in an hour. Convert the whole recipe to one system before you start, write the converted amounts on the page, and you will not have to do the arithmetic with wet hands.
How the conversion works
The US tablespoon is defined as 14.7868 ml, and the millilitre is defined as 1 ml. Divide the first by the second and you get 14.7868 — that is the whole derivation, and it is why the conversion is exact rather than approximate. No kitchen experiment was needed to establish it; the units were defined this way, so the ratio follows from the definitions. That is also why the same factor appears in every reliable conversion chart: there is only one right answer, and every source that uses US customary units agrees on it.
The one thing to check is which tablespoon your recipe means. This page uses the US customary tablespoon throughout. A metric cup is 250 ml, an imperial cup is 284 ml, and older recipes sometimes use a 'cup' that means whatever cup the writer had in the cupboard. If a recipe from outside the US gives an amount that looks wrong after converting — a cake with far too much liquid, a soup that is far too thin — the cup is the first suspect. Convert the recipe to grams once, write the grams on the recipe card, and the question never comes up again.
Rounding deserves a note too. The exact factor is 14.7868 to four decimal places, and the full value runs further (14.79 ml divided by 1.00 ml). For everyday cooking, rounding to two or three significant figures is fine: a 1% rounding error is invisible in a soup and barely noticeable in a cake. But round only at the end. If you round the factor and then multiply by a large amount, the rounding error grows with the amount — so keep the full factor through the calculation and round the answer, not the factor.
Volume is not weight
A conversion between two volume units is the same for every ingredient, but a conversion between volume and weight is not — and confusing the two is the most common conversion mistake in cooking. A cup of all-purpose flour weighs about 120 g spooned and levelled (King Arthur Baking), a cup of granulated sugar about 198 g, a cup of butter about 227 g, a cup of milk about 244 g (USDA), and a cup of honey about 336 g. All of those weights are approximate, because they depend on how the ingredient is measured: flour is spooned and levelled, brown sugar is packed at about 213 g a cup, and honey is poured.
Flour weight is the most disputed conversion in baking. King Arthur Baking lists 120 g per cup spooned and levelled, while other sources quote 125 g, 130 g and up to 142 g for a scooped cup. We use the King Arthur spooned-and-levelled value as primary, and the gap is a warning: if you scoop flour instead of spooning and levelling it, you can add 20 g or more per cup, which is enough to make a cake dry. Granulated sugar carries a smaller dispute — King Arthur lists 198 g per cup and the USDA rounds it to 200 g, a difference of rounding rather than a real disagreement. When a recipe matters, verify with a kitchen scale: weigh the ingredient instead of measuring it by volume, and every dispute on this page disappears.
Small amounts and precision
Small measures are where conversions matter most, because the same absolute error is a bigger share of a small amount. A teaspoon that is off by a quarter is a 25% error; a cup that is off by a quarter is a 6% error. That is why baking recipes give leavening, salt and spices in teaspoons and tablespoons rather than cups: the small unit is the precise one. Use proper measuring spoons, not cutlery — a teaspoon from the drawer can hold anywhere from 3 ml to 7 ml, which makes the conversion meaningless. Level every spoon with a knife, and do not pack a spoon measure unless the recipe says packed. For amounts under a teaspoon, a pinch is about a sixteenth of a teaspoon and a dash is about an eighth, but those are estimates, not conversions, and they belong in seasoning, never in baking. If a recipe needs half a teaspoon and you only have a teaspoon measure, fill it halfway and level it — or weigh it, because a scale reads half a teaspoon of baking soda at about 2.3 g without any conversion at all.
Frequently asked questions
What is the quickest way to measure 8 tablespoons in millilitres?
Use a measuring jug marked in millilitres and fill it to the 118.2941 millilitres line, reading at eye level on a flat surface. Counting it out in tablespoons one at a time is slower and easier to miscount. If you do not have a jug, a kitchen scale works for water-based liquids, since 1 ml of water weighs about 1 g — but that shortcut only holds for water-like liquids, not for oil or honey.
Why do recipes use tablespoons instead of millilitres?
Mostly tradition and the tools cooks already own. American recipes were written for American measuring cups, and metric recipes for metric jugs, and neither is going to change. The units themselves are equally good for measuring volume — the difference is only what your kitchen is equipped for. Rather than buying a new set of measures for every recipe, convert once and cook with the tools you have.
How many millilitres are in 1 tablespoon?
Exactly 14.7868 millilitres. Multiply any number of tablespoons by 14.7868 to get millilitres — for example, 6 tablespoons is 88.7206 millilitres. The conversion is exact because both units are defined volumes in the US customary system.
What is 4 tablespoons in millilitres?
59.1471 millilitres. Multiply 4 by 14.7868: 4 × 14.7868 = 59.1471. This is a common recipe amount — a third of a cup of cream, a few spoonfuls of oil — so it is worth knowing it is a straight multiplication with no special case.
Is a US tablespoon the same as a metric or imperial tablespoon?
Not always, and this is the biggest trap in unit conversion. This page uses the US tablespoon (14.7868 ml). A metric cup is 250 ml, an imperial cup is 284 ml, a US pint is 473 ml while an imperial pint is 568 ml, and an Australian tablespoon is 20 ml against the US 14.79 ml. If your recipe comes from outside the US, check which system it uses before converting — the factor on this page is correct for US measures only.
