single dual dimension

I hate workarounds, but, since you have only one dimension to modify, perhaps this clumsy method will do:

Create a drawing parameter in a relation such as DUAL=d# * conversion factor. Substitute for # the number in the dimension sysmbol. For inch to mm conversion, multiply by 25.4; for mm to inch conversion, multiply by .03937.

Then, in the drawing, modify the dimension to add a second line in the 'Dimension text' tab. Below where it shows @D, add a line that reads [&DUAL IN.] or use MM if it's a conversion to millimeters. The brackets are generally used to indicate secondary units.

Because, in the relation, you used an actual dimension symbol, the value of DUAL is parametric and will change appropriately if the associated dimension value changes in the part.

: Then, in the drawing, modify the dimension to add a second line in the 'Dimension : text' tab. Below where it shows @D, add a line that reads [&DUAL IN.] or use MM if : it's a conversion to millimeters. The brackets are generally used to indicate : secondary units. : Because you are adding this on the 'Dimension text' page, this is actually a note. It takes a value from the parameter DUAL and displays it with whatever the system NUM_DIGITS is set to. The detail setup file takes care of the usual difference between displayed decimal places of inch/metric dimensions with an option called DUAL_DIGITS_DIFF which allows indicating how many digits more or less the secodary units show. In a note, there's a way to accomplish the same thing. Immediately after &DUAL, add a decimal number in brackets to indicate the number of decimal places of the dimension to show. So, the note would read [&DUAL[.2] MM], changing the .2 to however many decimal places you need, usually one less for metric. You can use this in any parametric note to control the decimal display.
