Currently, this assumes your map utilizes a 24 mile hex. This is necessary to have a scale
factor by which to to multiply the area of your map shape to get the area in mi/km.

If your map uses a different scale, select a single hex and run this script. Replace the inches
value with the value in hexAreaInchesMap, select your shape, and run again to get sq mi / km.

By default, this rounds up the mi/km. Km is +/- 1 due to rounding. Will fix later.
