MGRS Coordinate Converter
MGRS (Military Grid Reference System) is a UTM-based grid reference system that expresses a location as a single alphanumeric string. It is widely used by NATO, in military operations and in search-and-rescue.
Features
- Two-way: latitude/longitude → MGRS and MGRS → latitude/longitude.
- UTM equivalent: each conversion shows UTM zone/easting/northing.
- Map preview: the result location is marked on the map.
How to Read MGRS
Example: 36S VK 87181 18889 — "36S" is the UTM zone and latitude band, "VK" is the 100 km grid square, and the remaining numbers are the easting and northing. More digits mean higher precision (10 digits ≈ 1 m).
Other Tools
For all coordinate formats use the GPS Format Converter, and for the MGRS of your current location use My Location.
Frequently Asked Questions
What is MGRS?
MGRS (Military Grid Reference System) is a UTM-based grid reference system used by NATO, military operations and search-and-rescue. Example: 35TPF1234567890. It expresses a location as a single alphanumeric string.
How do I convert MGRS to latitude/longitude?
Paste the MGRS string (e.g. 36SVK8718118889) into the box and press Convert to Coordinates; the tool shows latitude/longitude (decimal degrees and DMS), the UTM value and the location on the map.
What does MGRS precision mean?
The number of numeric digits in an MGRS string sets the precision: 10 digits (5+5) ≈ 1 m, 8 digits ≈ 10 m, 6 digits ≈ 100 m. This tool produces 1 m (5-digit) precision by default.
