Owing to their large luminosities per unit mass H II galaxies allow us to investigate in considerable detail the process of high mass star formation out to redshifts of cosmological importance. In this contribution we discuss the calibration of the correlation between the Hβ luminosity and the emission line width of H II galaxies as a distance indicator. We show that H II galaxies can be reliably used as distance indicators out to redshifts z > 3 provided that their line widths and fluxes can be determined with accuracies better than 10%.
