There is no reason at all for a 'nautical mile' (and no nautical kilometer either), the GPS system makes it possible to do away with it and to use the kilometer for all measurements of distance. Before World War Two aircraft navigation in Mainland Europe, Latin America and all other metric countries in that time, was metric: altitudes in meters, speeds in km/h and distances in km. No nautical miles were asked for before 1945. The only reason for keeping the nautical mile is tradition, the same thing that keeps the pint alive in Britain. I wonder what would have happened if there had been no Hitler and no world war with its upheavals following. I think this metrogical disaster would never have happened. The km^1 of the archives at least does not spill over into society, the ifp used in aircraft navigation does!
