MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 40KCB3638941688 means.

Component Value Meaning
UTM Zone 40 One of 60 vertical slices of Earth (6° wide each). Zone 40 runs 54° to 60° longitude.
Latitude Band K One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square CB A 100 × 100 km grid square within the zone/band. Column letter C (west–east) and row letter B (south–north).
Easting 36389 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 41688 Distance north within the 100 km square. Same resolution as easting (10 m).

Geohash Precision

A geohash encodes coordinates by subdividing the Earth into progressively smaller cells. Each extra character roughly halves the cell area. The table below shows Saint-Pierre Pierrefonds Airport's geohash at every precision level alongside the bounding box each level represents.
