COMMENTS
Volume of a cube with sides equal to one parsec.
The volume of a cubic parsec is used to describe the stellar density of star clusters.
The volume of cosmic voids is often measured in orders of magnitude of the cubic parsec. For example, the KBC void, a large, roughly spherical region of space with an underdensity of galaxies, containing the Milky Way, has a volume of about 10^8 cubic megaparsecs. - Felix Fröhlich, Oct 19 2017
