摘要：

I use the technique of Hernandez et al. to convert a recent calculation of the lattice-regulated quark condensate from an overlap action to a continuum-regulated number. I find Sigma ((MS) over bar)(mu = 2 GeV) =[282(6) MeV](3) x (a(-1)/1766 MeV)(3) from a calculation with the Wilson gauge action at beta = 5.9.
