Issue with grid and Blender Unit (Screenshot attached) I hope all is well. I've been having an issue with Grids and the Blender Unit during my 3D designs. 

For context, I want to set the Blender Unit (length) to be 1:1 with millimeters. I'm expecting that to mean that every subdivision of the grids should equal 1 mm. But, as you can see from the screenshot, it still equals 1000 mm or 1 meter. 

Does anyone happen to know what I'm doing wrong here?
Try setting the unit scale to .001. The drop down settings only affect what prefix is used to display the units, not the actual scaling.
