Is there a way to display the drawings unit of measure in a note?

I would like to place a note in our drawing borders that will return the value of the drawings unit of measure (from the Document Properties tab shown below). Does anyone know of a way I can pull this information into a note on the drawing? I want to do this so that if a user sets the default units to millimeters, the note will automatically update to read "millimeters" instead of reading "inches"
