We propose an empirical expression of the transition temperature Tc for amorphous superconductors including a number of nontransition metals, namely Tc = Aλ〈ω〉1/2/(〈ω〉/ω0 +(1+λ)/20), here A =(1/5)(K1/2). The comparison of the calculated values with experimental data and Garland theory for Tc shows that this empirical expression can describe the Tc values of amorphous superconductors satisfactorily.
