What is MGRS?
The Military Grid Reference System (MGRS) is a geocoordinate standard used by NATO militaries. It provides a way to reference locations using alphanumeric codes.
MGRS Format
An MGRS coordinate consists of:
- Grid Zone Designator: UTM zone + latitude band (e.g., 18S)
- 100km Square ID: Two-letter identifier (e.g., UJ)
- Numerical Location: Easting and northing within the square
MGRS in Geocaching
MGRS coordinates appear in military-themed puzzles and challenges:
- Military history caches
- NATO/defense themed puzzles
- Coordinate conversion challenges
- Multi-format waypoint puzzles
Relation to UTM
MGRS is based on the UTM coordinate system but adds the 100km square identification for easier communication and reduced ambiguity.
