Often when planning a boat trip, I want to calculate the running distance from a launch point to a fishing destination. Often I know (say from Maptech) the lat/long for both points but the conversion to miles is tricky.
I found a website that does it for you (albeit in km) ...but that's an easy conversion (1 km = .62 miles).

How do you do it?
