Yes,  but not everyone makes that assumption. Some people "assume"
that 1 unit is 1 inch and all their modelling is in feet and inches, or
if say modelling a room of a house, others might choose to assume that
1 unit was 1m others may prefer to work in cm.

It would be nice if people were encoraged to work off the same system,
and this would mean objects could be copied in an instant with a cut
and paste between files.   It's also more readable in my view.
