Number densityCost per volumeexact by definition
The reciprocal cubic metre is the SI unit of number density, counting how many discrete things occupy a unit volume: molecules, particles, defects or organisms. The quantity being counted is dimensionless, so the unit is a pure reciprocal volume. The relation to SI base units is exact by definition.

As a unit of cost per volume
Cost per cubic metre is a price attached to a volume of material, the base of this converter's volumetric cost scale. It is the standard basis for municipal water and sewer billing in metric jurisdictions, for bulk liquid contracts and for aggregate and concrete pricing. The conversions between the volume units here are exact wherever the underlying volume relations are exact.
