Online geographic coordinate conversions using the
GeoConvert (version 1.49)
converts between geographic (latitude and longitude) coordinates,
universal transverse Mercator (UTM) or
universal polar stereographic (UPS) coordinates, and the
military grid reference system (MGRS).
Examples of legal geographic locations are (these all refer to the
same place, Cape Morris Jesup on the northern tip of Greenland):
Latitude and longitude: MGRS:

The letter in following the zone number in the UTM position is
a hemisphere designator (n or s) and not the MGRS
latitude band letter. "north" or "south" can also be used,
MGRS coordinates are taken to refer to grid squares
(not to the intersections of grid lines). Thus in UTM
zone 38n, the square area with easting in [444 km, 445 km) and
northing in [3688 km, 3689 km) corresponds to the MGRS square
38SMB4488 (at 1 km precision).
When an MGRS coordinate is read, it is treated as the
center of the grid square.
The MGRS easting and northing are obtained
by truncation to the requested precision
Usually Output zone should be Match input or
standard. If the latitude and longitude are given, the
standard UPS and UTM zone rules are applied; otherwise the
UPS/UTM selection and the UTM zone match the input. The other
choices let you override this selection.
