%%%--- Operating System, Graphics card ---
OS: Windows 7
Graphics Card: Amd Radeon HD 6850
Processor: Intel(R) Core 2 Duo E8500 @ 3.16GHz

- Blender version with error, and version that worked ---

Not working:
Blender 2.68a
r58926

Working:
dont know

- Short description of error ---

Grid floor scale and unit scale have some unexpected behavior on newly added objects. New objects with a grid floor scaling of 0.1 can have a scale aspect of 1:100 instead of 1:10 compared to a grid floor scale of 1.0
And it can happen that new objects are 1:100 with grid scale 1.0 as well

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Remove all objects from the scene
Set Blender Units to "Metric"
Add a Cube (It will have Dimensions: 2m)
Add a Bezier Curve (It will have Dimensions: x: 2m)
Set Grid Floor Scaling to Scale: 0.01
Add another Cube (It will have Dimensions: 2m)
Add another Bezier Curve (It will have Dimensions x:0.2mm) !

%%%I'm going to mark this as a duplicate of this report:
https://projects.blender.org/tracker/index.php?func=detail&aid=36307&group_id=9&atid=498

There seems to be a lot of confusion around scale of added objects and grids/units...%%%

%%%maybe this is about confusion but i tested this as well and would say theres some scaling factor that should not happen at all, when changing a multiplier from 1 to 0.1 i would expect the units to behave like that and not scale from 1 to 0.001.%%%

%%%i still get the problem with r60379 so maybe you could have an other look at this issue. thanks%%%

%%%sorry the main issue is fixed, can you test the behavior of objec scale with something else than a cube? the grid floor scaling behaves differently for a cube thqan for every other object and i dont think grid floor scal should have influence on a object.%%%

%%%Cubes are handled in the same way as other objects, if there is still some problem - please give exact steps to redo.%%%

%%%ok here are the steps for the scaling issue i described:

set grid floor scale to 0.1
create a cube
create any other object
now set the grid floor scale to 1.0
creeate that cube again, note it has the same scale as cube from step 2
create that other object again and note the scale is different

%%%Bug is not fixed in r60379

Maybe this only happens with Bezier Curves.

Steps to reproduce:

Remove all objects from the scene
Set Blender Units to "Metric"
Add a Cube (It will have Dimensions: 2m)
Add a Bezier Curve (It will have Dimensions: x: 2m)
Set Grid Floor Scaling to Scale: 0.01
Add another Cube (It will have Dimensions: 2m)
Add another Bezier Curve (It will have Dimensions x:0.2mm) <--- error!%%%
