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.
