In the United Kingdom, a pint of beer contains 568 ml. This measurement is a legally defined standard for draught beer and cider sales in British pubs and restaurants. Understanding pint-to-milliliter conversions is useful for consumers tracking alcohol intake and bartenders and servers pouring accurate portions.
Quick Summary
Here is a quick overview of how many ml are in a pint of beer in the UK:
- 1 pint = 568 ml
- 1 US pint = 473 ml
- 1 ml = 0.00211338 pints
- 568 ml is the legally defined standard pint volume for draught beer and cider in the UK
So in the UK, if you order a pint of beer at a pub or restaurant, you can expect to receive 568 ml of beer in your glass.
Defining the UK Pint
Since 1824, the pint has been officially defined as equal to 568 ml in the UK and Ireland. This volume measurement was formalized in the Weights and Measures Act of 1824, which legally standardized a variety of customary units used in the British Imperial system of measurement.
The UK pint is 20% larger than the US pint, which is defined as 473 ml. This difference has historical roots. In 1824, the two countries were using different reference temperatures to define a fluid ounce, leading to diverging pint sizes over time. Nowadays, the larger UK pint is entrenched in British drinking culture and hospitality.
Breakdown of the UK Pint in Milliliters
Here is a detailed breakdown of the pint-to-milliliter conversion:
- 1 UK pint = 568 ml
- 1 UK fluid ounce = 28.41 ml
- 1 UK pint = 20 imperial fluid ounces
- 20 x 28.41 ml per ounce = 568.2 ml
So a UK pint contains 568.2 ml, which is rounded down to 568 ml for simplicity.
Other Common Pint-to-Milliliter Conversions
In addition to 568 ml in a UK pint, here are some other common pint-to-milliliter conversions:
| Unit | Milliliters |
|---|---|
| 1 US pint | 473 ml |
| 1 half pint | 284 ml |
| 1 fluid ounce (UK) | 28.4 ml |
| 1 fluid ounce (US) | 29.6 ml |
Why the UK Pint is Legally Defined
There are a few key reasons why the UK pint is legally defined and standardized:
- Fairness in trade – Standardizing the pint ensures customers at pubs and bars get a fair amount of beer for the price they pay. It prevents short pours.
- National pride – The pint glass is an iconic symbol of British drinking culture. Standardizing it protects this cultural legacy.
- Simplifies commerce – A uniform pint volume facilitates commercial activities like taxing, pricing, and inspecting draught beer and cider sales.
By law, the vessels used to serve pints, such as beer glasses and mugs, must be officially calibrated to hold 568ml with a margin of error no greater than 5ml. Glasses and mugs designed for the UK market are manufactured to these specifications.
Legal History and Standards
A few key legal milestones in codifying the UK pint:
- 1824 – Weights and Measures Act legally defines the imperial pint as 568 ml.
- 1963 – Weights and Measures Act mandates tolerance of 5ml for draught beer and cider containers.
- 1985 – Weights and Measures Act of 1985 retains the 568ml pint definition.
- 2006 – Licensing Act makes 568ml pint mandatory for pubs, bars, restaurants, and other licensed premises.
Today, the pint is enshrined in British weights and measures law, as well as alcohol licensing regulations. Both pint glasses and metered taps must pour accurate 568ml servings, within a slim tolerance for error.
Imperial vs. Metric System in the UK
Even though the pint is an imperial unit, metric milliliters are still used regularly in the UK. Here’s a brief history:
- 1965 – UK begins transitioning to the metric system.
- 1995 – Pint officially retained as legal unit alongside metric system.
- 2007 – EU law makes metric mandatory for packaged goods and produce.
- Pint still legal for draught beer and cider only.
So millennials in the UK grew up with a hybrid system. While metric dominates for volume measures like bottled drinks, pints persist in pubs and bars. Most British peopletoggle seamlessly between the two systems.
Why the Pint Endures in the UK
Despite metrication efforts, the pint remains entrenched in British drinking culture for a few reasons:
- Nostalgia – Pints are icons of British and Irish pub culture.
- Traditions – Beer is often served in pints at festivals, sports matches, and community events.
- Tourism – Pubs and pints draw tourists seeking an authentic British experience.
- Industry lobbying – Powerful pub and brewing lobbies campaigned to keep the pint legal.
Basically, the pint glass is woven into the fabric of British social life and identity. That cultural weight makes this imperial tradition persist.
How Pint Glasses Pour 568 ml
Purpose-built pint glasses and mugs achieve the 568 ml serving volume through design features:
- Narrow, tall shape promotes full fills.
- Thick, sturdy walls minimize breakage.
- Calibrated etched fill lines guide perfect 568 ml pours.
- Angled sides facilitate smooth draining with minimal waste.
The most common pint glass types are:
Nonic Pint
These modern, smoothed-edge glasses minimize chipping. Their slight outward taper at the top inhibits splash-back.
Tulip Pint
This flared lip glass collects a frothy beer head. Its stem helps prevent hand warmth from heating beer.
Conical “Beer Mug”
These mugs allow frothy heads while maintaining thick froth. Their durability makes them popular for events and promotions.
Though shapes vary, all reputable pint glasses and mugs hold 568 ml volumes at brim fill.
Tips for Pouring and Drinking Pints
To get the most from drinking a proper British pint, here are some serving tips:
- Store glasses chilled to maximize foam when poured.
- Hold glass at 45 degree angle when pouring.
- Pour gently initially, then vigorously in the middle, finishing gently.
- Leave 1-2 cm room at the top for foam.
- Wait for foam to partially settle before topping up.
- Pour with glass tilted to help regulate flow rate.
Here are some tips for drinking pint beers:
- Take small initial sips to avoid excessive foam.
- Gently swirl beer to distribute flavor and aromas.
- As foam settles, top glass up halfway through the pint.
- Alternate drinking with conversation to regulate warming.
- If drinking alone, pair with water to control intake pace.
Mastering proper pouring and savouring techniques enhances the rich pint-drinking tradition.

- West Country – Dry, tart, funky, farmhouse-style cider from Southwest England.
