How much is a brick unit in Blender?
A 0.5 by 0.5 with 0.6 height block in blender units is a 1x1 blockland brick.
And a 0.5 by 0.5 with 0.2 height in blender units is a 1x1 blockland plate.
Also, an easy way to get the length and width of a 2x2 brick in blender is to match it up with the the smaller squares in the 3d view grid (with the view at an angle)
