In Illustrator, when I open a file in which there is objects with spacing of 0.1in, and Illustrator's grid is also set to 0.1in, then everything is fine.
But when I open the same file in Inkscape, and set Inkscape's grid to 0.1in too, it doesn't correspond, the objects aren't on the same scale.

So either the grid in Inkscape is wrong, or the file isn't opened to it's normal size (or what else?)
Do you have any idea how can I fix this problem?
Thanks in advance, I don't like Illustrator and would like to use Inkscape instead but I can't really, because of this problem
