Choose units of measurement (point longitude and latitude)

[MantvydasZuokas1]

The ArcGIS.com map viewer includes a measuring tool with the capability to find point’s longitude and latitude (i.e. in degrees). Additionally it is desirable for this tool to be able to show location as X and Y, (i.e. in projected coordinates system’s units). The user should be able to choose measurement units based on operational layers’ and basemap’s coordinate systems’ units.

This is in most users Top Ten wish lists - the ability to identify locations based upon cursor location or point click.
Very surprising that this is still not there in April 2014.

For us in  the UK OSGB36 Co-ordinate display is the requirement.

Would like to get coordinates back in British National Grid or just to use the coordinate system of the current basemap.
