There is a software I work with that still uses cubits. We have been told not to use it, it was only included because AutoCad still recognizes cubits.

" it was only included because AutoCad still recognizes cubits"

Whoever told you that must be still laughing. AutoCAD uses two units: the base unit, and a secondary unit that is twelve times the base unit. It is totally up to the user to decide what the base unit is. Architects call it an inch, while for engineering purposes it can be either a foot, a meter, or a millimeter. The software doesn't have any way of knowing, or caring what you call it. (I have been using AutoCAD for 25 years)
