mJy are a unit of specific intensity, or flux at a particular frequency.  Integrated intensity is therefore mJy times Hz (or 1/s).  One can convert Hz to km/s by determining what velocity is implied by a given frequency shift \Delta\nu/\nu, and that is what has been done here, with \nu \approx 23. GHz.
