Yes that is what i want to achieve.

I feel like i should explain what i am trying to do more to get a better answer.

I am trying to design a new title board and i want that one to be in metric (mm or cm) as i am used to working in metric more. I have a project at the moment the requires that i work in US customary units (inch / feet) so i need to have my model space be in inches.

And that is why i posted to ask on how to do this. As it stands my DWG units and insertion units are in inches and my paper space is as well. When i try to alter things in my title board i am prompted to do so in inches. FOr example i want to stretch a rectangle in my title board so the dimensions are prompted in architectural imperial format which i am not used to working with beyond a certain limit of fractions.

It would be much easier for me to have the paper space be in metric and the orthographic stretching, text size, etc be in mm or cm so i can alter them quickly, with ease and precision.
