[USER=109010]@Rich54[/USER] had a great approach. Here is another.
I used a vector rose as an example and assumed that with 10 x 10 mm pixels (or 1cm x 1cm pixels) that I want to make an overall mosaic of 100 squares by 100 squares which would end up being 1 meter on a side.
1) Since you want 100 square by 100 squares create a 100 pixel by 100 pixel document.
2) Place the embeded vector image into that document. Here is the vector document below.

3) After it is embedded my defaults have it come in as a Smart Object. Right Click on that Smart Object Layer and rasterize (this gives you the pixelated image at 100 pixels by 100 pixel):

4) You now want to scale this image so you have it in mm where the whole image is 1 meter in size followed by putting in grid lines.
What you do is use File > Image Resize with the the dimensions set to "cm" the values set to 100 by 100 cm (= 1 meter final size) and set the resolution to 20 pixels per cm and MOST IMPORTANT set the resmpling to Nearest Neighbor. You will end up with this result (note I chagned the rule from pixels to cm yet other then that it is the same as the smaller pixel image:

Not all you need is a grid. I did this with a pattern fill of the following pattern which is two sides with whtie 1 pixel wide in a 20x20 pixel pattern with the rest being transparent:

I then create a fill on a separate Layer using this pattern to create a grid that is 1 cm on a size with a white grid that is one pixel wide:

And your are done. You can print sections of this image to scale and use that for your pattern to put in the tiles
Just another way to approach the problem.
Hope this helps
