Density map and scale bar problems

     So, I'm trying to create a kernel density map with some point data I geocoded from some FARS tables on vehicle accidents around the DC beltway area but I'm having trouble getting the map units and scale bar to work at the same time.  I first tried leaving the shapefile as it was originally projected in the GCS_North_American_1983 CRS but I couldn't get the map units in the kernel densisty dialogue box to show anything in km, m, miles, etc.  It just showed up as map_units and I couldn't change anything.  Then I tried defining the projection as maryland state plane, which let me use the correct map units of meter that I wanted but when I went to put a scale bar in the main map the numbers were way off. It was showing the whole area of DC as like .0005 miles or something crazy like that?  Then I tried using the project tool to see if that would change anything but the scale bar was still weird. What am I doing wrong?
