We report a study of non equilibrium relaxation in a two-dimensional random field Ising model at a nonzero temperature. We attempt to observe the coarsening process from a different perspective with a particular focus on three dynamical quantities that characterize the kinetic coarsening. We give a simple generalized scaling theory of coarsening supported by numerical results. The excellent data collapse of the dynamical quantities justifies our proposition. The scaling relation turns out to be universal in characterizing the kinetic coarsening.
