Using 1 minute of arc on the earth = 6000 ft = 1 nautical mile to UNDERSTAND and use in a simple way for best accuracy to plot a position or scale off an object on a map when used for sailing walking flying and driving. This makes 1 second of arc = 100ft and does not interfere with use of statute miles or kilometers for engineering and construction. Degrees Minutes (or Miles nautical) and Seconds DMS. GPS plus all maps and charts are based on ARC latitude and longitude not survey miles and kilometres. Ideally the scientific standard should be an ancient 6000 ft nautical mile. Not an old random metal stick in London or Paris John.
