If you are mid-recipe and need this number fast: 1 millilitre is 0.0021 pint. That is the answer, and the rest of this page is the table, the worked examples and the pitfalls for when you have more time. The conversion is exact, because both units are defined volumes in the same system — unlike a cup of flour, which changes weight with the ingredient, a millilitre is always the same volume, so the factor never varies.
Unlike a conversion between cups and grams, which depends on what is in the cup, this one has a single right answer. A millilitre is a defined volume and a pint is a defined volume, so the ratio between them is fixed by the definitions themselves. That makes it reliable in a way that ingredient conversions are not — and it means the table on this page is correct for every liquid, from water to cream to stock, without exception.
Conversion table

| 15 millilitres | 0.0317 pint |
| 30 millilitres | 0.0634 pint |
| 60 millilitres | 0.1268 pint |
| 100 millilitres | 0.2113 pint |

Read the table in either direction. Going from millilitres to pints, multiply by 0.0021; going back, divide by 0.0021 or multiply by 473.1765. The middle rows are the ones recipes use most — 100 millilitres is 0.2113 pint, and 250 millilitres is 0.5283 pint. If your amount is not in the table, multiply it by 0.0021 and you have the answer. For a quick check: 1 millilitre is 0.0021 pint, 2 millilitres are 0.0042 pint, and 10 millilitres are 0.0211 pint.
Worked examples
Measuring without the right cup. Your millilitre measure is in the dishwasher and you only have a pint measure. 60 millilitres is 0.1268 pint, so count out 0.1268 level pint and you are done. It is slower than using the right measure, but it is exact — this is a fixed unit conversion, not an estimate. The only thing to watch is levelling: a heaped pint is not a pint, and three heaped spoonfuls can add a whole extra millilitre to a delicate batter.
A dressing or sauce, made to taste. A salsa verde comes together in the bowl: 60 millilitres of oil, then the same again of vinegar, then seasoning. In pints that first pour is 0.1268 pint. Dressings are forgiving — a little more or less oil will not ruin them — but knowing the conversion means you can scale the dressing up for a party without guessing, and you can write the scaled version down so it tastes the same next time.
A large pot of stock or soup. A stock pot takes 500 millilitres of water, which is 1.0567 pints. At this size the jug is the only sensible tool — counting it out in millilitres would take all afternoon. Fill the jug to the 1.0567 pints line, pour, and repeat if the pot needs more. And remember that stock reduces as it simmers, so measure the water going in, not the stock coming out.
How the conversion works
The US millilitre is defined as 1 ml, and the pint is defined as 473.1765 ml. Divide the first by the second and you get 0.0021 — 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 millilitre your recipe means. This page uses the US customary millilitre 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 0.0021 to four decimal places, and the full value runs further (1.00 ml divided by 473.18 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.
Batch cooking and large volumes
Large volumes are where the bigger units earn their keep. Counting out a gallon in cups means sixteen pourings and sixteen chances to lose count; one reading on a jug marked in the larger unit is faster and more accurate. For stock, jam, pickling and drinks, measure in the largest unit your jug offers, and convert once. Remember that large batches do not scale perfectly: a quadrupled jam needs longer to reach setting point, a quadrupled stock needs longer to reduce, and a quadrupled cake batter needs a bigger tin or two tins, not a deeper one. Seasoning and leavening scale by less than the volume, so add them in stages and taste as you go. Write the scaled amounts on the recipe card with the date, because a batch that worked deserves to be repeatable, and a batch that did not deserves a note about what to change. And label everything that goes in the freezer with the contents, the amount and the date — future you will be grateful.
Frequently asked questions
Does this conversion change for different ingredients?
No — volume is volume. One millilitre of water, milk, oil, honey or stock is always 0.0021 pint. What changes between ingredients is the weight: a cup of all-purpose flour weighs about 120 g, a cup of granulated sugar about 198 g and a cup of honey about 336 g, so a conversion to grams always depends on the ingredient. But a conversion between two volume units never does, which is why this page has one table for every ingredient.
What is the quickest way to measure 250 millilitres in pints?
Use a measuring jug marked in pints and fill it to the 0.5283 pint line, reading at eye level on a flat surface. Counting it out in millilitres 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 millilitres instead of pints?
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 pints are in 1 millilitre?
Exactly 0.0021 pint. Multiply any number of millilitres by 0.0021 to get pints — for example, 120 millilitres is 0.2536 pint. The conversion is exact because both units are defined volumes in the US customary system.
What is 100 millilitres in pints?
0.2113 pint. Multiply 100 by 0.0021: 100 × 0.0021 = 0.2113. 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.
