What are the values of $\kappa$ and $\epsilon_0$ in the capacitance equation?

This was the expression giving the capacitance of a parallel plate capacitor, $C=\kappa \epsilon_0 A/d$. $A$ is the cross-sectional area, $d$ is the distance between the plates, $\epsilon_0$ is the permittivity of free space ( $\epsilon_0 = 8.854 \times 10^{=12}$F/m, a constant of nature), and $\kappa$ is the dielectric constant of the material between the plates. The value of $\kappa$ is 1 for vacuum, and $>1$ for media (so capacitance increases when there's a dielectric between the plates).
