If you've ever stood in a UK pub and wondered exactly how much beer is landing in your glass, or tried to follow a British recipe using American measuring cups, you've bumped into one of the oldest arguments in cooking: a pint is not a pint everywhere. The calculator above sorts that out in a couple of taps, but it helps to know what's actually going on behind the numbers - so let's get into it.
How many mL are in a pint?
1 US liquid pint = 473.18 mL — that's roughly 95 mL less, or about 20% smaller than its British cousin.
Both countries inherited the word "pint" from the same old English measuring system, but they never agreed on how big one should actually be. The UK stuck with the imperial system that was standardised in 1824, while the US kept using an older English wine-trade measure. Neither side is wrong exactly - they're just measuring against a different baseline, which is exactly why a dedicated pint to mL converter is more useful than trying to remember a single number.
UK pint to mL vs US pint to mL: the full chart
Here's a quick-reference table for the amounts people actually look up most - everything from a half pint at the bar to a full case. Punch any of these into the calculator above and you'll get the same figures, plus as many decimal places as you like.
| Pints | UK (Imperial) pint to mL | US (liquid) pint to mL |
|---|---|---|
| ¼ pint | 142.07 mL | 118.29 mL |
| ½ pint | 284.13 mL | 236.59 mL |
| 1 pint | 568.26 mL | 473.18 mL |
| 2 pints | 1,136.52 mL | 946.35 mL |
| 3 pints | 1,704.78 mL | 1,419.53 mL |
| 4 pints | 2,273.05 mL | 1,892.71 mL |
| 6 pints (a 6-pack) | 3,409.57 mL | 2,839.06 mL |
| 8 pints (1 gallon) | 4,546.09 mL | 3,785.41 mL |
Why is a UK pint bigger than a US pint?
It comes down to two different gallons. Back in 1824, Britain passed the Weights and Measures Act and defined the imperial gallon as the volume of 10 pounds of water - which works out to exactly 4.54609 litres. Split that into eight pints and you land on 568.26125 mL, the figure your calculator uses today.
The Americans never adopted that reform. They carried on using the old English "wine gallon" of 231 cubic inches, a measure that dates back centuries earlier. Once the international inch was standardised in 1959, that old wine gallon settled at exactly 3.785411784 litres - and an eighth of that gives you the US pint of 473.176473 mL. So really, it's the US pint that's "unchanged" and the UK pint that got redefined - most people assume it's the other way round.
How to use this pint to mL converter
The tool above is built to answer any pint, litre or fluid ounce question in one screen, without ads getting in the way. Here's what each part does:
Pick your starting unit. Tap the dropdown next to the first box and choose what you're converting from - UK Pint, US Pint, Millilitres, Litres, UK or US Fluid Ounces, US Cup, or either Gallon.
Type in your amount. The result updates as you type, so you'll see the converted figure change in real time rather than waiting for a "convert" button.
Choose your target unit in the second dropdown - this is what your amount gets converted into.
Set your accuracy. The "Accuracy" dropdown lets you choose anywhere from 0 to 15 decimal places. It defaults to 4, which is plenty for everyday cooking and shopping, but if you're doing lab work, brewing calculations or anything that needs more precision, bump it up.
Hit the swap button (the circular arrows icon) to instantly flip the "from" and "to" units without retyping anything.
Use the quick presets - ½ Pint, 1 Pint, 2 Pints, a 6-Pack, 1 US Pint, or 1 Litre - to jump straight to a common amount with one tap.
Watch the Fill Level glasses. This is the part most converters don't have: as soon as you enter an amount, the two glasses on the right fill up to show exactly how many UK pints and how many US pints that amount equals, side by side. It's a genuinely quick way to see the size difference rather than just reading two numbers.
Copy your result with the copy icon on the teal result card - it copies the exact figure (matching whatever accuracy you've set), ready to paste straight into a recipe, spreadsheet or shopping list.
Check your recent conversions by opening the "Recent conversions" dropdown - handy if you're converting a few different amounts in one go and want to compare them afterwards. There's a "Clear history" option if you'd rather start fresh.
Open the quick reference table at the bottom any time you want to see every supported unit converted to millilitres and litres in one place, without cluttering the main calculator.
Visual comparison: UK pint vs US pint vs a litre
Numbers on their own don't always tell the story, so here's the size difference laid out as a bar - the same idea as the Fill Level glasses above, just flattened out.
A quick real-world example
Say a British recipe asks for a pint of stock, but your measuring jug is marked in US cups because that's what you brought back from a trip to Boston. A UK pint works out to just under 2.4 US cups (568.26 ÷ 236.59), not the 2 cups you'd use for an American pint. It's a small difference, but on a stew for six people, it adds up.
Frequently asked questions
An imperial (UK) pint is exactly 568.26125 mL, almost always rounded to 568.26 mL in everyday use.
A US liquid pint is exactly 473.176473 mL, usually written as 473.18 mL.
Yes. A UK pint is about 20% larger than a US pint - roughly 95 mL more per pint, mainly because the two countries use different definitions of a gallon.
Half a UK pint is 284.13 mL. Half a US pint is 236.59 mL.
A litre holds about 1.76 UK pints, or about 2.11 US pints.
The pint is one of the few imperial units still protected by law in the UK - draught beer, cider and milk in returnable bottles are legally required to be sold in pints, which is why the measurement has stuck around despite the country's broader switch to metric.
