MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 55KGT0375347683 means.

Component Value Meaning
UTM Zone 55 One of 60 vertical slices of Earth (6° wide each). Zone 55 runs 144° to 150° 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 GT A 100 × 100 km grid square within the zone/band. Column letter G (west–east) and row letter T (south–north).
Easting 03753 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 47683 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 Hamilton Island Airport's geohash at every precision level alongside the bounding box each level represents.
