I’m still toying with my units they are giving me a bit of trouble at the moment.
I’m a structural designer by trade and use Tekla / Revit / Autocad for my designs, they all seem to export different into unreal engine. So I’m trying to cut out the middle man and use 3ds max for all my importing / exporting.

One click of a button and it sets the scene up to the units, also you can add in a temporary human to check scaling.
Also some handy information on scaling here -
