So the Geocaching app only displays coordinates in a DMD "degrees/minutes decimal" format (DD°MM.MMM') while my car GPS accepts coordinates as a destination (most aftermarket do... Garmin, TomTom, etc), but mine only wants it in straight "decimal degrees" (DD.DDDD°) or traditional DMS "degrees/minutes/seconds" (DD°MM'SS")... I've tried to estimate the seconds part of the decimal minutes, but didn't work (500m or so off). This app is very small and doesn't require any special permissions to operate.
Degrees Miles and Seconds DMS.60 minutes = 60 nautical miles. --- 1 minute of arc on the earth = 2 Roman miles = 6000 ft = 1 nautical mile = plotting accuracy for scaling an object on a map. It can be used for sailing walking flying and driving. So This makes 1 second of arc = 100ft and does not interfere with use of statute miles or kilometers for engineering and construction. John.
