when I resize I want to see the real width\length\dept of the object instead of the x=1 y=1 z=1.
Is there a way to do this?
Are you looking for the Dimensions in 3D view > Tool shelf (N)?
You can also change the units these values are represented in. By default they are displayed in "blender units" (BU), which are equal to meters. To do this, adjust the settings in Properties > Scene > Units:
I should also point out that the Scale of an object is not limited to 0-1. For example:
The Scale object property is really factor by which you can non-destructively shrink or stretch the object in any given axis without modifying the mesh.
No, the three numbers you are talking about in the 3D view header, while you are scaling an object, is the scale factor (example cube is 2" scale factor of 1.5, the cube is now 3").
If you want to change a object by typing in the dimensions you can do so in object mode in the properties region, explained in my answer here.
The process is
If you want units like meters or inch, you can go to the properties panel, then to scene and then to the tab units. Here you can choose metric or imperial. The dimensions is in meters or inches.
