The point is that OBJ doesn't have a set scale - it just uses units, without specifying how long a unit is. Your 1m cube probably came from modo or some other application that uses 1 OBJ (and Poser) unit = 1m, if you'd used Hexagon (base unit 1cm as I recall - as I think it is in 3DS Max) the cube would have been even larger. That's one of the reasons that the DAZ Studio OBJ importer/exporter has multiple presets - so that it can use the right conversion factor from the source application's scale to its own 1 unit = 1 cm.
