Geodesic coordinate calculator online

On this page you can convert between geographic coordinates (in decimal degrees, degrees-minutes-seconds), Standard UTM, and NATO UTM. Download the Excel template if you want to do bulk conversions.

Enter the coordinates in any format, then click convert to view the results. Android app available.

The best GPS I can recommend: Good, nice and inexpensive Garmin eTrex 22x, a cooler one Garmin GPSMAP 65s and a semi-wild one Garmin GPSMAP 67i.

About Coordinate Systems

Geographic Coordinates (Latitude/Longitude): System that uses angles from the center of the Earth to points on the surface. Latitude measures north/south angles from the equator, and longitude measures east/west angles from the Greenwich meridian.

UTM (Universal Transverse Mercator): Cartographic projection system that divides the world into 60 zones of 6 degrees of longitude. It provides coordinates in meters and is widely used in topographic mapping.

NATO/MGRS (Military Grid Reference System): Extension of the UTM system used by NATO and military forces that adds grid identifiers for greater precision in position references.
