If you've ever stood in a UK supermarket holding an American recipe that calls for "2 pints of stock," you'll know the confusion is real. A pint isn't just a pint — the UK and the US measure it differently, and neither one matches the metric litres most of the world cooks and shops in. The calculator above handles the maths for you, but it helps to actually understand what's going on, so let's walk through it properly.
Quick answer: 1 UK (imperial) pint = 0.568 litres. 1 US pint = 0.473 litres.
The UK pint is about 20% larger than the US pint — that's the single most useful fact on this page, so remember it before you go any further.
How to Use This Pints to Liters Converter
The tool above looks simple, but it's built to handle far more than a one-off conversion. Here's what each part actually does:
Choose UK Pint or US Pint
Tap the toggle at the top of the calculator before you enter anything. This tells the converter which pint you mean — a UK (imperial) pint or a US (liquid) pint — since they're two genuinely different volumes, not just a rounding difference.
Type into either box
You don't have to convert pints to litres only — type a number straight into the Litres box and it works backwards, converting litres to pints instead. Both boxes stay in sync automatically as you type.
Use the swap button
The little up-down arrow between the two boxes flips the direction of the conversion — whatever number is currently showing in Litres becomes the new starting amount, recalculated instantly.
Adjust the decimal precision
The "Decimals" dropdown in the top corner controls how many decimal places the result shows, from 2 all the way up to 15. Most people never need more than 4, but if you're doing scientific or lab-grade work, the extra precision is there.
Try the quick preset chips
Common amounts — half a pint, 1, 2, 4, 8 pints, or 1 litre — are one tap away underneath the input boxes, so you don't need to type anything for the conversions you'll look up most often.
Explore the four tabs
Visual shows your amount as filled glasses so you can see it, not just read it. Compare lines up UK pints, US pints and litres side by side as bars. Recent keeps a running list of what you've converted this session (with a Clear button if you want a fresh start). Reference gives you a ready-made pints-to-litres chart without needing to type anything at all.
Copy your result
The Copy button next to the result grabs the full "X pt = Y L" line so you can paste it straight into a recipe, a shopping list, or a message, without retyping the numbers yourself.
UK Pint vs US Pint: Why They're Not the Same
This trips up more people than it should. Both countries inherited the pint from old English measures, but they standardised it differently. The UK fixed its gallon — and therefore its pint — under the Weights and Measures Act of 1824, based on the volume of 10 pounds of water. The US, meanwhile, kept an older "wine gallon" definition from before independence, which is smaller. Run that difference down to a single pint and you get:
| Measurement | UK (Imperial) Pint | US (Liquid) Pint |
|---|---|---|
| Volume in litres | 0.56826125 L | 0.473176473 L |
| Volume in millilitres | 568.26 ml | 473.18 ml |
| Fluid ounces | 20 UK fl oz | 16 US fl oz |
| Fraction of a gallon | 1/8 UK gallon | 1/8 US gallon |
| Where it's used | UK, Ireland, and draught beer in several Commonwealth countries | United States, US recipes and packaging |
So a US pint isn't a rounding error away from a UK pint — it's roughly 95 ml smaller, which is the difference between a full glass and one that's noticeably short. If you've ever wondered why an "authentic" pint of beer feels bigger in a British pub than an American bar, now you know: it genuinely is.

If you just need a number and don't want to type it into the calculator, here's a chart covering the amounts people actually search for:

|---|---|---|
| 0.5 pt | 0.284 L | 0.237 L |
| 1 pt | 0.568 L | 0.473 L |

How Many Pints Fit in Common Bottle Sizes?
This one's genuinely handy if you're stocking a fridge or scaling a recipe written in litres:
Where You'll Actually Run Into This
- Milk deliveries: Doorstep milk in the UK is still often sold in pint bottles — a standard pint is 568 ml, so a 4-pint carton is roughly 2.27 litres.
- Beer and cider: A "pint" at the bar in Britain is a legally defined 568 ml. Order the same "pint" in the US and you'll get about 95 ml less.
- Cooking from US recipes: American recipes measure liquids in US pints and cups, which are smaller than UK equivalents. If a US recipe calls for 2 pints of stock, that's roughly 0.95 litres — not 1.14 litres as a UK pint conversion would suggest.
- Paint, oil and engineering fluids: Some older UK trade specs still quote quantities in imperial pints, which is where a quick, accurate converter earns its keep.
The Formula (If You Want to Do It Yourself)
You don't need the calculator for a rough estimate — the maths is simple once you know the two constants:
- UK pints to litres: litres = pints × 0.56826125
- US pints to litres: litres = pints × 0.473176473
- Litres to UK pints: pints = litres ÷ 0.56826125
- Litres to US pints: pints = litres ÷ 0.473176473
Common Mistakes to Avoid
- Assuming "pint" means the same thing everywhere. Always check whether a recipe, spec sheet or conversation is using UK or US pints before you convert.
- Mixing up fluid ounces. A UK fluid ounce (28.4 ml) is also slightly smaller than a US fluid ounce (29.6 ml) — so "20 fl oz" doesn't mean the same volume on both sides of the Atlantic either.
- Rounding too early. If you're converting in stages (pints → cups → ml, for example), round only at the very last step, or small errors add up.
Frequently Asked Questions
How many litres are in a UK pint?
Exactly 0.56826125 litres, or 568.26 millilitres. This is a legally defined figure under UK weights and measures law, not a rounded approximation.
How many litres are in a US pint?
A US liquid pint equals 0.473176473 litres, or 473.18 millilitres — about 95 ml less than a UK pint.
Is a UK pint bigger than a US pint?
Yes. A UK (imperial) pint is roughly 20% larger than a US (liquid) pint — 568 ml compared to 473 ml.
How many pints are in a litre?
One litre is about 1.76 UK pints, or about 2.11 US pints. The exact figures are 1.7597539863927 UK pints and 2.11337641887 US pints.
How many millilitres are in a pint?
A UK pint is 568.26 ml. A US pint is 473.18 ml. Which one applies depends on whether you're working with a UK or US measurement.
Why does a UK pint of beer taste "bigger" than a US pint?
Because it genuinely is bigger — by about 95 ml, roughly a sixth more liquid in the glass. It isn't just perception; the UK imperial pint and the US liquid pint are two different legal measurements.
Is there also a US "dry pint"?
Yes, though it's rarely used outside the US and mainly appears for measuring produce like berries. The US dry pint (about 550.6 ml) is different again from both the US liquid pint and the UK imperial pint, so it's worth double-checking which one a recipe or listing actually means.
How accurate is this converter?
It uses the exact legal conversion factors (0.56826125 for UK pints and 0.473176473 for US pints), not rounded estimates, and you can display up to 15 decimal places using the Decimals setting if you need that level of precision.
