In adobe XD cant change the Unit, can you share what is the requirement needed in inches.
Please feel free to update this discussion in case you need further assistance and we will be happy to help.
I assuming you are trying to print some of your design work. Might initial thought would be to export your design as PDFs and use InDesign or Illustrator to perform what you might need to do. XD isn't really designed for print based work.
