I am trying to measure straight-line distance from residence to facility. I have both of these locations in latitude and longitude (degrees) in separate layers in shapefiles. These layers indicate which facility each resident went to. I have converted the projection to be UTM (meters). I am trying to measure distance in kilometers and am not sure how to do this. I cannot do a near feature because we cannot assume that all residents traveled to the nearest facility.
I calculated the the hypotenuse of a triangle through a function in excel and have the "distance" in a single number, but this is in degrees, so I am not sure if it can be converted to meters, or if the whole operation should be done differently.
