To liters: multiply by 10¹⁸. To km³: multiply by 10⁶. To petaliters: multiply by 1,000.
1 EL = 10¹⁸ L = 10¹⁵ m³ = 10⁶ km³ = 1,000 PL.
For example, 1 Exaliter (EL) = 2.199692e+17 Gallon (UK) (gal (UK)).

The exaliter is a unit of volume equal to 10¹⁸ liters, or one million cubic kilometers.
1 EL = 10¹⁸ L = 10¹⁵ m³ = 10⁶ km³ = 1,000 PL.
To liters: multiply by 10¹⁸. To km³: multiply by 10⁶. To petaliters: multiply by 1,000.
No practical applications — this scale exists only for astronomical and theoretical comparisons.
All the water on Earth (oceans, ice, groundwater, lakes, rivers, atmosphere) totals about 1.386 EL.
Almost never encountered, so mistakes are rare. The main risk is confusion with other 'E' prefixes (e.g., eV in energy).
Think of the exaliter as the 'planet volume' unit. Earth's oceans ≈ 1.335 EL. Prefix: exa = 10¹⁸ = quintillion.
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.
