We extract the charm quark mass and the strong coupling constant from the charmonium current correlators calculated with n f = 2 + 1 Mobius domain wall fermions. We match our lattice calculation for the temporal moments of the correlator with perturbative result known up to fourloop order, and extract the charm quark mass with uncertainty less than 1%. Using the temporal moments, we also confirm the correlators in the vector channel to be consistent with the experimental data for the R-ratio.
