We investigate whether radio emission primarily traces star formation in radio-quiet active galactic nuclei (RQ AGN). Our sample consists of 5223 galaxies detected by the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey with multi-wavelength counterparts up to a z $\approx$ 6 limit. The sources were classified using the infrared-to-radio luminosity ratio (q$_{\rm IR}),$ X-ray luminosity cuts, and mid-infrared colour cuts into RQ AGN (10.4$\%$), radio-loud AGN (RL AGN, 33.2$\%$), and star-forming galaxies (SFGs, 56.4$\%$). We calibrated the star formation rate (SFR)-1.4 GHz radio luminosity (L$_{\rm 1.4~GHz}$) relation for both SFGs and RQ AGN. We found that SFRs correlate positively with L$_{\rm 1.4~GHz}$ for both populations, which was expected since they are both non-radio excess and they follow the infrared-radio correlation. From the SFR-L$_{\rm 1.4~GHz}$ correlation, we measured the average Spearman's rank correlation coefficients ($\rho$) of $\rho_{\rm SFGs}~\approx$ 0.806 $\pm$ 0.004 and $\rho_{\rm RQ~AGN}~\approx$ 0.805 $\pm$ 0.009, and best-fit slopes (m) of m$_{\rm SFGs}$ $\approx$ 0.866 $\pm$ 0.006 and m$_{\rm RQ~AGN}$ $\approx$ 0.926 $\pm$ 0.003, respectively. The similarity between the measured slopes and Spearman's coefficients for both SFGs and RQ AGN indicates that radio continuum emission in RQ AGN mainly traces star formation.
