NAME
       unitconv	- simple energy	and length units converter

SYNOPSIS
       unitconv	[unit] value
       unitconv	[unit] expression

DESCRIPTION
       unitconv	 is  a	simple	energy	and length units converter (written in
       Tcl). It	is a utility program of	 xcrysden  package  (http://www.xcrys-
       den.org/).

ENERGY UNITS
       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

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

       angs -- Angstrom

       bohr -- Bohr radius

       m -- meter

EXAMPLES
       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.
