A program can use the UDUNITS library to convert between units.  This
is exactly what the udunits(1) utility does.  Whether or not a program
is interactive is irrelevant to using the UDUNITS library.  See the
installed manual page, udunits(3), for information on using the library
and the udunits(1) utility (which comes with the distribution) for a
example on using the library.  For what you want to do, the following
sequence of calls will, in general, be made:

    utInit(path)

    utScan(spec, &unit)

    utPrint(&unit, buf)

    utTerm()
