        float convertToTwips​(java.lang.String foValue)
              throws FOPException
        convert given value to RTF units
        Parameters:
        foValue - a value like "12mm" TODO: tested with "mm" units only, needs work to comply with FO spec Why does it search for period instead of simply breaking last two Characters into another units string? - Chris

        FOPException
