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.xcrysden.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  com-
     mand 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 en-
     ergy 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.
