When measuring areas, I often display results in square feet. If I need acres, I have to change the display option to acres. I need both units displayed, so going back and forth is a bit tedious plus I have no on screen documentation of both results unless I add one of the results to a post comment. An option to select a 2nd user specified unit would be a great help. A typical result could be "9781.61 sq. ft. = 0.224 ac." (A conversion to metric would also be useful.) Three significant figures is customary in math circles.
Thanks...
