Cubic kilometers to Cubic meters converter

To convert cubic kilometers to cubic meters, enter the value in the first field. The result in cubic meters is calculated automatically using the exact conversion factor.

1 km³ = 1000000000 m³
1 m³ = 1 × 10^-9 km³

Formula: m³ = km³ × 1000000000
km³ = m³ × 1 × 10^-9

Definitions: 1 km³ = 1000000000 m³

The cubic kilometer (km³) is a cube one kilometer on each side, or one billion cubic meters. It is used in earth sciences and hydrology for very large volumes such as lake and reservoir capacities, glacier and ice-sheet volumes, and annual river flows.

The cubic meter (m³) is the SI unit of volume: a cube one meter on each side, equal to 1000 liters. It is used for large quantities such as water consumption, concrete, gravel, soil, natural gas, and the space inside rooms and cargo containers.
