100 km Square XR A 100 × 100 km grid square within the zone/band. Column letter X (west–east) and row letter R (south–north).
Easting 56491 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 83559 Distance north within the 100 km square. Same resolution as easting (10 m).
