To liters: multiply by 10¹². To cubic meters: multiply by 10⁹. To cubic miles: multiply by 0.23990.
1 km³ = 10⁹ m³ = 10¹² L = 10¹⁵ mL. One cubic mile ≈ 4.168 km³.
For example, 1 Cubic Kilometer (km³) = 0.000001 Exaliter (EL).

The cubic kilometer is a unit of volume equal to a cube one kilometer on each side (10⁹ m³), used for extremely large volumes.
1 km³ = 10⁹ m³ = 10¹² L = 10¹⁵ mL. One cubic mile ≈ 4.168 km³.
To liters: multiply by 10¹². To cubic meters: multiply by 10⁹. To cubic miles: multiply by 0.23990.
Measuring lake volumes (Lake Baikal ≈ 23,615 km³), ice sheet volumes, and major reservoir capacities.
Earth's total ocean volume is about 1.335 billion km³. All human-made reservoirs combined hold only ~8,000 km³.
Underestimating the scale — 1 km³ = 10⁹ m³ = one trillion liters. It is a colossal volume.
Imagine a cube 1 km on each side — it would hold enough water to fill 400,000 Olympic swimming pools.
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.
