Fusion
Fusion usually does a good job reading the unit info. Have you got a sample DWG file you can share? You might need to zip the file to attach it.

-dwgunits indicates that the AutoCAD was done in Inches (actually back in 2002 AutoCAD was Unitless).
If you have access to AutoCAD run the -dwgunits command to convert to mm units.
When I open the file with ZW3D it lists the units as Inches. I don't have AutoCAD to double check, @TheCADWhisperer might be able to help.
Size imported into Zw3d and Fusion are the same 26.864 inches or 682.337 mm

Just noticed Fusion seems to be positioning some part differently. Rhino on the left Fusion right, not sure which is correct.

Also notice the part on the right is a different size in Fusion. Not sure what's going on there.

@TheCADWhisperer Didn't you used to be able to set the INSUNITS even in older versions of AutoCAD so files used as blocks had their units set? Seem to remember setting this in AutoCAD Lt years ago.

INSUNITS does not do what most people think - it does not set units (there was no unit information in the dwg format set, kind of like stl now) - it merely scales geometry.
AutoCAD was unitless years ago, INSUNITS was simply SCALE set to apply appropriate scale factor depending on what the user selected as their intended "units".
@Anonymous
Since you don't have a newer version of AutoCAD - you will have to scale your sketch in Fusion.
I would double and triple check everything (dimension and fully define) after scaling as I saw some questionable stuff in the AutoCAD dwg file. Don't trust it as is.
@Anonymous Can you save as a DXF instead then use Insert DXF in Fusion and override the units to mm on import. Insert DXF is on the insert menu.
