@stuart_harrower ,User can change unit of existing document and new document and work-space with the help of below method as shown in video. Three example are given in video to change unit.
1) If user is using any unit frequently then he can set that unit with the help of account setting and place there preference. Now user can get required unit in new document which he given in account setting preference.
2) User can change unit in existing document.
3) User can change unit in new created document.

You can also use mixed units by simply adding the unit after the value (100mm or 4inch). This is handy in cases where you need to use for example 2 by 4 inch wood but like to use mm in length and overall dimensions.

Realizing, of course, that 2x4 lumber is something less than 2 inches deep and 4 inches across, at least here in the US.  What is the comparable "nominal" dimension in the rest of the world - 50 x 100 mm?

Indeed, 100 x 50 (note opposite order) it is, and our rough sawn timber (which is what we call lumber) is pretty much those dimensions,
when "dressed" (not sure if you use the same term) it naturally gets smaller, but is still referred to as being the same nominal size

Ok, smart guys - I'll change my example case to one where you have bolts and fasteners in inches (or other parts bought from 'inch-land') but want to do main design in millimeters

Interesting how things change across the major ponds.  @andrew_troup - I think that it is the same process in the US; the rough sawn lumber starts out at 2" x 4" and is finished to something smaller.

Same thing with 2x4" here in Finland
