To liters: multiply by 163.659. To UK gallons: multiply by 36. To US barrels: multiply by 1.373.
1 UK barrel = 36 UK gal = 288 UK pt = 5,760 UK fl oz ≈ 163.659 L ≈ 1.637 hL.
For example, 1 Barrel (UK) (bbl (UK)) = 1.636592e-13 Petaliter (PL).

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.
The petaliter is a unit of volume equal to 10¹⁵ liters, or 1,000 cubic kilometers.
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
No everyday practical use. Used for expressing very large natural water volumes in scientific literature.
All the world's rivers contain approximately 2.12 PL of water. Earth's ice caps hold about 26.5 PL of freshwater.
Rarely encountered, so the main mistake is not understanding the scale: 1 PL = one quadrillion liters.
Petaliters describe planet-scale volumes. Earth's total freshwater ≈ 35 PL. The prefix chain: kilo, mega, giga, tera, peta.
