Quick Reference
UTM Format: Zone + Letter + Easting + Northing (e.g., 51S 377561 4621522)
Example: 40.7128N, -74.0060W = 18T 583959 4507351
Pro Tip: Each UTM zone is 6 wide. Crossing zone boundaries without recomputing causes severe false easting discontinuities (~500+ km) across zone boundaries in autonomous navigation engines.
