In this Letter we report how the influence of the interparticle dipolar interactions, computed by the volume sample concentration $c$, can be described in a general way if scaled by the dimensionless parameter $c_{0}=2K/M_{S}^{2}$. This scaling $c_{0}$-parameter is derived from the energy equation governing the system by using simple arguments, and its meaning is analogous to the normalization of the influence of the external magnetic field H by the anisotropy field of the particles $H_{A}=2K/M_{S}$. We use a Monte Carlo technique to test the usefulness of this $c_{0}$ parameter for interpreting the controversial evolution of the blocking temperature (\textit{$T_{B}$}) \textit{vs.} $c$ reported in the literature, finding that the $T_{B}(c)$-curves of different particle types follow the same trend if scaling $c/c_{0}$.
