MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 50JMK0236265716 means.

Component Value Meaning
UTM Zone 50 One of 60 vertical slices of Earth (6° wide each). Zone 50 runs 114° to 120° longitude.
Latitude Band J One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square MK A 100 × 100 km grid square within the zone/band. Column letter M (west–east) and row letter K (south–north).
Easting 02362 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 65716 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 Perth International Airport's geohash at every precision level alongside the bounding box each level represents.
