Wing's metric system

[FlevasGR]

Hello people, i was making something on wings when a question came in to my mind.
Many game engines like unity they use an 1 by 1 scale which makes the development easyer in case you cant scale the model later. Usualy the docs from those enviroments are telling us to go to 3DS max and change the scale to 1 by 1 but in wings 3d i dont even know if its possible.
The only thing that helps me out is the grid

So my question is this: Does each square represents one perfect square meter and when i move a cube 1 unit on any axis is it an actual meter?
