function uPS = gsw_uPS

% gsw_uPS                             unit conversion factor for salinities
%==========================================================================
%
% USAGE:
%  uPS = gsw_uPS
%
% DESCRIPTION:
%  The unit conversion factor for salinities (35.16504/35) g/kg (Millero et
%  al., 2008).  Reference Salinity SR is uPS times Practical Salinity SP. 
%
% OUTPUT:
%  uPS  =  unit conversion factor for salinities                   [ g/kg ]
