The UK (imperial) gallon is a unit of volume equal to 160 UK fluid ounces, or exactly 4.54609 liters.
1 UK gal = 4 UK qt = 8 UK pt = 160 UK fl oz = 4.54609 L ≈ 1.201 US gal.
To liters: multiply by 4.54609. To US gallons: multiply by 1.20095. To cubic meters: multiply by 0.00454609.
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 oil barrel is a unit of volume equal to 42 US gallons (approximately 158.987 liters), the standard for measuring crude oil and petroleum products.
1 oil barrel = 42 US gal = 158.987 L = 34.97 UK gal = 5,376 US fl oz.
To liters: multiply by 158.987. To US gallons: multiply by 42. To cubic meters: multiply by 0.158987.
Crude oil trading and pricing, refinery throughput, national oil production statistics, and petroleum reserve reporting.
Global oil consumption is about 100 million barrels per day. Oil is no longer actually shipped in barrels — the unit persists purely as a standard of measurement.
Confusing the oil barrel (42 gal) with the US liquid barrel (31.5 gal). Always use 'bbl (oil)' or specify the type.
Oil is priced per barrel (~42 gallons). When you see '$70/barrel,' that means about $1.67/gallon before refining and distribution costs.
