UK road signs (mpg), older fuel consumption references, and some Caribbean and Middle Eastern markets that still use imperial units.
A UK gallon is about 20% larger than a US gallon. A car rated at 40 mpg (UK) gets only about 33 mpg (US).
Misinterpreting UK mpg as US mpg — UK figures look higher because the imperial gallon is larger.
UK gallon ≈ 4.55 L ≈ 1.2 US gallons. The UK gallon was defined so that 1 gallon of water = 10 pounds.
The UK (imperial) barrel is a unit of volume equal to 36 imperial gallons, or approximately 163.659 liters.
1 UK barrel = 36 UK gal = 288 UK pt = 5,760 UK fl oz ≈ 163.659 L ≈ 1.637 hL.
To liters: multiply by 163.659. To UK gallons: multiply by 36. To US barrels: multiply by 1.373.
Historical UK brewing trade, legacy contracts and legal references, and traditional measurements in some industries.
The UK barrel (36 imp gal ≈ 164 L) is different from both the US liquid barrel (31.5 US gal ≈ 119 L) and the oil barrel (42 US gal ≈ 159 L).
Confusing UK, US, and oil barrels — they are all different sizes. Always specify the barrel type.
A UK barrel = 36 imperial gallons ≈ 164 liters. Remember: there are at least 3 common barrel sizes — UK, US, and oil.
