The relation was first examined by [[Maarten Schmidt]] in a 1959 paper in which he proposed that the SFR surface density scales as some positive power <math>n</math> of the local gas surface density.<ref name="schmidt59" /> i.e.
			:<math>\Sigma_{SFR} \propto (\Sigma_{gas})^n</math>.
			In general the SFR surface density <math>(\Sigma_{SFR})</math> is in units of solar masses per year per square parsec <math>(M_\odot ~\textrm{ yr}^{-1} \textrm{ pc}^{-2})</math> and the gas surface density in grams per square parsec <math>(\textrm{g}~\textrm{pc}^{-2})</math>. Using an analysis of gaseous helium and young stars in the solar neighborhood, the local density of [[white dwarfs]] and their [[luminosity function]], and the local helium density, Schmidt suggested a value of <math>n \approx 2</math> (and very likely between 1 and 3). All of the data used were gathered from the Milky Way, and specifically the solar-neighborhood.

			More recently, [[Robert Kennicutt]] examined the connection between gas density and SFR for nearly 100 nearby galaxies to estimate a value of <math>n = 1.4 \pm 0.15</math>.<ref name="kennicutt98" />
