Scale to grid

Would it be possibly to scale face of an object so that it would show 4.000 instead of 0.430 and whole object would change accordingly. Or change grid settings.

And also could grid show different color on integral units and different for 0.100 values. Subdivisions set to 1 isnt really practical.

Blender unit can’t be changed. You need to scale up your object until it all reads 4.

The color setting for the gird is located under User Preference window. It’s the icon with “i” symbol. Select Theme on the base bar and change Default to Rounded; it’s the top button on left end column. I have no idea what “Rounded” means! So it took me a long time to find where color setting was! But, that will bring up Grid button on the next column where color can be set.
