An MGRS grid reference is a point reference system. When the term 'grid square' is used, it can refer to a square with a side length of 10 km (6 mi), 1 km, 100 m (328 ft), 10 m or 1 m, depending on the precision of the coordinates provided.
The quadrants are numbered sequentially, from west to east, starting with the northernmost band. Specifically, the northwest quadrant is “1”; the northeast quadrant is “2”; the southwest quadrant is “3”; the southeast quadrant is “4”. Each quadrant is identified by a six-character designation.
Coordinate conversion is composed of a number of different types of conversion: format change of geographic coordinates, conversion of coordinate systems, or transformation to different geodetic datums. Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems.

The coordinate format can be chosen via Tools → Options → 3D View → Show Lat/Long. There are many ways to obtain coordinates: There are many ways to obtain coordinates: Move the mouse pointer to where you want, then use the keyboard to select the Menu item Edit → Copy View Location to copy the coordinates to the clipboard.
[1] [2] [3] This can improve human comprehension by providing reference of scale, as well as making actual distance computations more efficient. [4] Paper maps often are published with overlaid rectangular (as opposed to latitude/longitude) grids to provide a reference to identify locations.
The GJ local grid. For example, on a GEOREF chart, Naval Air Station Patuxent River (38°17′10″N 76°24′42″W) / (38.286108, -76.4291704) is located (to the nearest minute) at position GJPJ3417. To locate the position from the coordinates, proceed as follows: Right from 180° longitude to longitude zone G
The second digit (x0xx through x8xx) indicates the number of tens of degrees latitude (north in global quadrants 1 and 7, south in global quadrants 3 and 5) of the 'minimum' square boundary (nearest to the Equator), i.e. a cell extending between 10°N and 20°N (or 10°S and 20°S) has this digit = 1, a cell extending between 20°N and 30°N ...
