Where did the grid dimensioning /drawing dimensions icon/selection go?

I can’t find anything in HELP and can’t find WHERE did the grid dimensioning (drawing units) go?
I ant to change from mm to inches and can’t figure out how to in the lastest release! WHERE did the config get buried in the new menu/icons
system?
HELP!!!

Hi @ptegler, the Units menu can be found in the top right corner, next to the Orientation Cube.
