About Gallon (UK) (gal (UK))
Definition
The UK (imperial) gallon is a unit of volume equal to 160 UK fluid ounces, or exactly 4.54609 liters.
Mathematical Relationship
1 UK gal = 4 UK qt = 8 UK pt = 160 UK fl oz = 4.54609 L ≈ 1.201 US gal.
Conversion Formula
To liters: multiply by 4.54609. To US gallons: multiply by 1.20095. To cubic meters: multiply by 0.00454609.
Practical Applications
UK road signs (mpg), older fuel consumption references, and some Caribbean and Middle Eastern markets that still use imperial units.
Interesting Facts
A UK gallon is about 20% larger than a US gallon. A car rated at 40 mpg (UK) gets only about 33 mpg (US).
Common Mistakes
Misinterpreting UK mpg as US mpg — UK figures look higher because the imperial gallon is larger.
Educational Tips
UK gallon ≈ 4.55 L ≈ 1.2 US gallons. The UK gallon was defined so that 1 gallon of water = 10 pounds.
About Petaliter (PL)
Definition
The petaliter is a unit of volume equal to 10¹⁵ liters, or 1,000 cubic kilometers.
Mathematical Relationship
1 PL = 10¹⁵ L = 10¹² m³ = 1,000 km³ = 1,000 TL. One exaliter = 1,000 PL.
Conversion Formula
To liters: multiply by 10¹⁵. To km³: multiply by 1,000. To teraliters: multiply by 1,000.
Practical Applications
No everyday practical use. Used for expressing very large natural water volumes in scientific literature.
Interesting Facts
All the world's rivers contain approximately 2.12 PL of water. Earth's ice caps hold about 26.5 PL of freshwater.
Common Mistakes
Rarely encountered, so the main mistake is not understanding the scale: 1 PL = one quadrillion liters.
Educational Tips
Petaliters describe planet-scale volumes. Earth's total freshwater ≈ 35 PL. The prefix chain: kilo, mega, giga, tera, peta.
