Abstract
Using the parameters in the chiral Lagrangian obtained by MILC from their unquenched lattice QCD calculations with 2+1 flavours of sea quarks, I estimate the chiral condensate. I obtain the result 〈ψ¯ψ〉(2 GeV)/nf = −(259±27 MeV)3 in the MS¯ scheme. I compare this value to other determinations.
