If you use maps and charts a lot in your work like I do - whether for navigation or survey purposes - you will find this information useful.
The U.S. Military Grid Reference System (MGRS) conveniently flattens the world out into 6° by 8° geographic areas, each of which is given a unique identification, called the Grid Zone Designation - essentially, 100,000-meter square "chessboards".
Latitude & Longitude vs UTM grids.
Each square is identified by two letters called tie 100,000-meter square identification. This identification is unique within the area covered by the Grid Zone Designation.
100,000 meter MGRS Square Designators
If you've spent more than a day in uniform, you already know this, and you've probably relied upon land navigation skills at least once in your life. For everybody else - to include the military guys - you must be aware that the world is becoming smaller, but yet at the same time increasingly more complex.
Back in the good old days a soldier could navigate and operate happily with a lensatic compass and a 1:50,000 mapsheet, nowadays navigational tools may include civilian GPS devices and 1:250,000 Joint Operational Graphic (JOG) charts - which give Lat / Long but no MGRS.
This tool allows you to convert a coordinate from latitude longitude, into
MGRS (Military Grid Reference System) coordinates using the WGS 84 standard. Enter the LAT / LONG coordinates in decimal degrees (convert degree minutes seconds to decimal degrees).
