The next step is to find the unit dimension your data is associated from the Unit Categories table below. Once the unit dimension is located, double click on the category icon, implemented as a component (part) in the Canvas View, to obtain a Part Properties dialog for the unit category. You can also right click on the category icon and select Properties from the context menu to open the dialog. The details of the dialog contents are explained in the next section, Choosing Unit Conversion Objects.
Based on the classified lists of units from Table A.2 through A.7 in the IEEE/ASTM SI 10-1997 Standard (Annex A.4.1 Organization), we created nine categories with their dimensions listed as following:
