We find a strong correlation between these two quantities. On average, the ratio between the radio continuum and the CO emission is constant (within a factor 3) both inside the same galaxy and from galaxy to galaxy. The star formation efficiency deduced from the radio continuum depends weakly on general galaxy properties. A comparison is made with another similar analysis performed using the H alpha luminosity as star formation indicator.ELETTRONICOenConference paperhttp://www.astroscu.unam.mx/RMxAC/vol17.html2003RMxAC..17...90GFIS/05 - ASTRONOMIA E ASTROFISICA
