If you want to change the units or decimal places that are specified in the input dialog boxes or result tables, open the Edit menu and select Units and Decimal Places. You can also click the button that is available in almost all dialog boxes and in the table toolbar.
In the "Units and Decimal Places" dialog box, you can enter user-defined settings.
The "Units and Decimal Places" dialog box is described in the chapter Changing Units of the RFEM manual.
