In this paper, we use quasars calibrated from type Ia supernova (SN Ia) to constrain cosmological models. We consider three different X-ray luminosity ($L_{ X}$) - ultraviolet luminosity ($L_{ UV}$) relations of quasars, i.e., the standard $L_{ X}$-$L_{ UV}$ relation and two redshift-evolutionary relations (Type I and Type II) respectively constructed from copula and considering a redshift correction to the luminosity of quasars. Only in the case of the Type I relation, quasars can always provide effective constraints on the $\Lambda$CDM model. Furthermore, we show that, when the observational Hubble data (OHD) are added, the constraints on the absolute magnitude $M$ of SN Ia and the Hubble constant $H_0$ can be obtained. In the $\Lambda$CDM model, the OHD measurements plus quasars with the Type I relation yields $M$ =$-19.321^{ +0.085}_{ -0.076}$, which is in good agreement with the measurement from SH0ES ($M=-19.253\pm{ 0.027}$), and $H_0$ = $70.80\pm3.6~\mathrm{ km~s^{ -1}Mpc^{ -1}}$, falling between the measurements from SH0ES and the Planck cosmic microwave background radiation data.
