Convert UTM easting and northing to latitude and longitude, and back, on WGS84.
How this tool works
The Universal Transverse Mercator system divides the world into 60 north-south zones and gives positions as an easting and northing in meters, which makes distance math easy on paper maps. The tool implements the standard WGS84 conversion series in both directions: enter a zone, hemisphere, easting, and northing to get latitude and longitude, or enter latitude and longitude to get the UTM reference, accurate to well under a meter.
What you can do with it
- Convert UTM references from survey documents, hiking maps, or GIS files to plain coordinates
- Convert GPS coordinates to UTM for fieldwork or paper map plotting
- Get the zone and latitude band letter for any point
- Cross-check values from other software
Why use it
UTM appears constantly in surveying, hiking, and scientific data, but consumer map apps only speak latitude and longitude. This is the missing translator, running entirely in your browser.
