The gas‐to‐dust ratio in the interstellar medium of nearby spiral systems and dwarf irregular galaxies has been obtained by using mainly the compiled data by Schmidt and Boller (1992a). The gas‐to‐dust ratio of dwarf irregulars is larger by about one order of magnitude than for spiral galaxies, on the average. A relation between the gas‐to‐dust ratio and the metallicity, represented by the abundance of oxygen, has been detected.
