In response to a forum question from @Sabo3 :- https://scratch.mit.edu/discuss/topic/446076/ This project demonstrate converting a list entry number into X and Y co-ordinates. Click on the numbers to see the X and Y co-ordinates. As it stands, the co-ordinates begin at 1. If you want to change it so they begin at 0, change the value of the "Co-ords start at 1?" variable from TRUE to FALSE inside the project.
