Cubic meters to cubic kilometer Conversion
1 cubic meters (m³) is equal to 0.000000001 cubic kilometer (km³).
1 m³ = 0.000000001 km³
or
1 km³ = 1000000000 m³
Formula
To convert a volume from cubic meters (m³) to cubic kilometer (km³), divide the volume in cubic meters by 1000000000
v(km³) = v(m³) / 1000000000
Examples:
Convert 10 cubic meters to cubic kilometer:
v(km³) = 10m³ / 1000000000 = 0.00000001 km³
