Convert units between Metric and Imperial in AutoCAD

In AutoCAD, the unit is a generic unit with no direct connection to metric or imperial units.  The simple way is to use Scale command in Model space to resize either scale up by 2.54 or vice versa.

Note, any measure text would need to be manually recalculated.
