The image has a size of 1372*1931 (see the viewBoxi); after scaling it should be
55*77 units (I don't know how many mm a rect with width="55" and height="77"
is, anyone ?) but that should be larger than 4cm.

When something like this happens, I use code like this:

    int out = int (value * 10000f);
    printf ("%d.%05d", out/10000, out%10000);

In C, you could of course use %.5f but not in Java.
