The STING is a CARMA 3mm survey of nearby galaxies. We will present a comprehensive analysis of the relationship between the star formation rate surface density and molecular gas surface at the sub-kpc level in the STING sample. To construct the tracers of molecular gas and star formation rate surface densities, respectively, we will use high resolution (3-5") CO (J=1-0) data from CARMA and the mid-infrared 24 micron data of comparable resolution (6") from Spitzer Space Telescope. We measure the relation in the bright region of these galaxies. In our preliminary analysis we find an approximately linear relation and no strong trends for either the logarithmic slope or the molecular depletion time across the range of galaxy masses sampled (10^9-10^11.5 Msun).
