Please find [the article](https://wiki.opendesign.com/index.php/How_do_I_determine_the_drawing_units_(millimeters,_inches,_feet,_or_kilometers)_of_a_drawing%3F) in our wiki. INSUNITS variable stores drawing units starting with AutoCAD 2000. Some vertical applications like Land Desktop Development store units in another way - in dictionaries probably because INSUNITS was not introduced yet by the moment. DWGUNITS command still exists for backward compatibility and note that it has an option to synchronize INSUNITS.
