Umrechnungstabellen

Die folgenden Umrechnungstabellen sind ganz nuetzlich wenn man in den Staaten Teile bestellt und wissen moechte ob der Kram auch passt. Die Amis rechnen namelich heute noch in den uns fremden Zoll/Inch Werten. Es ist absolut erforderlich diese Werte genau zu ueberpruefen wenn man eine Bestellung abgibt. Es ist unerlaesslich alle Details schriftlich zu documentieren, sonst geht es mit grosser Wahrsceinlichkeit schief und man kriegt Teile die entweder unbrauchbar sind oder nur mit Aufwand passend gemacht werden koennen.
