\f0\fs24 \cf0 k_BT = 1.3806*10^\{-23\} J/K  300K = 1.3806*10^\{-23\}  6.02*10^\{-23\} * 300 J//mol = 2.5 kJ/mol = (2.5/4.182) kCal/mole \
Note: TABI energy unit is kCal/mol and APBS energy unit is kJ/mole thus if using TABI, we should use pK_a = (\\Delta G)*4.182/2.5/2.303 while APBS use pK_a=(\\Delta G)/2.5/2.303.}
