MGRS Converter

Convert WGS84 latitude/longitude and MGRS both ways, then inspect the grid zone, 100 km square, UTM center, represented cell bounds, precision ladder and round-trip check.

MGRS grid-cell audit

Convert the reference, then inspect the actual represented grid cell

Enter decimal or DMS latitude/longitude, or paste an MGRS reference. The workbench exposes the WGS84 cell center, corners, UTM coordinates, precision ladder and round-trip check.

Copyable MGRS audit

Precision boundary. MGRS identifies a square grid cell. Decoding on this page reports the center and corners of that cell instead of implying exact point precision. This WGS84 implementation covers the normal UTM/MGRS latitude range from 80°S to 84°N; polar UPS/MGRS is outside this tool’s scope.

MGRS names a grid cell

MGRS is derived from UTM and is normally used from 80°S to 84°N. The number of easting/northing digits controls cell size; decoding reports the cell center so precision is not overstated.

Datum matters

This page uses WGS84, matching the existing WebToolArc UTM tools. A coordinate from another datum can shift if interpreted as WGS84.
