MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 51RUQ4866966651 means.

Component Value Meaning
UTM Zone 51 One of 60 vertical slices of Earth (6° wide each). Zone 51 runs 120° to 126° longitude.
Latitude Band R One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square UQ A 100 × 100 km grid square within the zone/band. Column letter U (west–east) and row letter Q (south–north).
Easting 48669 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 66651 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 Shanghai Dachang Air Base's geohash at every precision level alongside the bounding box each level represents.
