 u  stands for "basic unit" ...


        gtroff (like many other programs) requires numeric parameters to
        specify various measurements.  Most numeric parameters9 may have a
        measurement unit attached.  These units are specified as a single
        character that immediately follows the number or expression.  Each of
        these units are understood, by gtroff, to be a multiple of its basic
        unit.  So, whenever a different measurement unit is specified gtroff
        converts this into its basic units.  This basic unit, represented by a
        aCu', is a device dependent measurement, which is quite small, ranging
        from 1/75th to 1/72000th of an inch.  The values may be given as
        fractional numbers; however, fractional basic units are always rounded
        to integers.
