The clumpy structure of two spiral galaxies NGC 3184 (SAB(rs)cd HII) and NGC 3938 (SA(s)c HII) is analyzed at different wavelengths (8 and 24 μm, NUV, Hα, and CO) using an algorithm called ``Clumpfind2d'' (Williams et al. 1994). Based on the clumps found by this algorithm, the star formation rates (SFR) of both galaxies are calculated by different methods from the literature, which vary depending on the wavelength used in each case. The dispersion on the results obtained from these methods is large. For each wavelength, a specific relation between the luminosity and area of each clump is found. New formulas for calculating the SFR at all the studied wavelengths are proposed. These formulas result from the extrapolation of the Hα formula taken from the literature via the relation found in this same project. The mean multiwavelength SFR for NGC 3184 is found to be 0.72+/-0.40 M_&sun; yr^{-1}, while for NGC 3938 it is 0.33+/-0.09 M_&sun; yr^{-1}.
