MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 18TXM2516356523 means.

Component Value Meaning
UTM Zone 18 One of 60 vertical slices of Earth (6° wide each). Zone 18 runs -78° to -72° longitude.
Latitude Band T One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square XM A 100 × 100 km grid square within the zone/band. Column letter X (west–east) and row letter M (south–north).
Easting 25163 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 56523 Distance north within the 100 km square. Same resolution as easting (10 m).
