       unitconv - simple energy and length units converter


       unitconv [unit] value
       unitconv [unit] expression


       unitconv  is  a simple energy and length units converter (written in Tcl). It is a utility
       program of xcrysden package (


       The following energy units are  supported.   The  following  list  contain  the  "unit  --
       description" pairs, where the unit is to be specified on the command line.

       au -- Hartree

       ry -- Rydberg

       ev -- eV (electron volt)

       kjm -- kJ/mol

       kj -- kJ

       kcalm -- kcal/mol

       kcal -- kcal


       The following length units are supported (usage as above):

       angs -- Angstrom

       bohr -- Bohr radius

       m -- meter


       Convert a value from eV to other energy units:

       unitconv ev 3.25

       Calculate  an  expression (values in Rydberg unit) and convert to other energy units (note
       that expression must be quoted):

       unitconv ry "-103.134567 - (-240.691356 - -2*17.543471)/2"

       In expression also mathematical functions available in tclsh can be used.
