Dear Paolo
I know one of them is in Ry and another one in Ha,but when I compare them
they are different
scf:  total energy              =  -243.33284101 Ry

CP:  ekinc         :       10.67409      10.67409 (AU)
   ekin          :      153.58930     153.58930 (AU)
   epot          :     -458.58466    -458.58466 (AU)
   totel energy  :     -258.18270    -258.18270 (AU)
   temperature   :        0.00000       0.00000 (K )
   enthalpy      :     -258.18270    -258.18270 (AU)
   econs         :     -258.18270    -258.18270 (AU)
   pressure      :       -3.47982      -3.47982 (Gpa)
   volume        :      488.11442     488.11442 (AU)
Thanks
