How may liters in a barrel of beer?

1pt=16oz in the US.

That means that there are 8pts in a gallon.

There are 31 gallons in a US barrel of beer.

Therefore 248 US Pints in a true US barrel (however, if you're looking for usable pints, then subtract a few for spillage and the bottom of the barrel... never tasty...)

In the UK, there are 163.7liters (or rather, litres) of beer in their barrel.

There are 33.8140227oz in a liter.

An Imperial Pint=19.2152067oz.

Therefore: 163.7liters x 33.8140227oz/liter DIVIDED BY 19.2152067oz/imperial pt=
