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) = 3.519508e+19 Fluid Ounce (UK) (fl oz (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 fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
1 UK fl oz = 1/20 UK pt = 1/160 UK gal ≈ 28.4131 mL. It is about 4% smaller than a US fluid ounce.
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
Paradoxically, the UK fluid ounce is smaller than the US fluid ounce (28.41 vs. 29.57 mL), even though UK pints and gallons are larger.
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
UK fl oz ≈ 28.4 mL, US fl oz ≈ 29.6 mL. The UK has more fl oz per pint (20) vs. US (16), but each UK fl oz is smaller.
