How to generate checkerboard in mm

How can I generate checkerboard in mm? There is only option to create it in pixels. I want to have cell size 30 mm after printing the image.

I = checkerboard(n,p,q)

Is there a way to calculate conversion from mm to pixels and create target checkerboard?

As far as I know, this isn't something that MATLAB can currently do. The reason is that MATLAB (and most other programs) do not know the physical dimensions of your screen, or the size of paper you're printing on, when creating the image.

Here is what someone at RIT did: http://twiki.cis.rit.edu/twiki/pub/MVRL/Documentation/checkerBoard.m, and your problem is an inverse problem: where you need to find the number of pixels per mm.
