Convert UTM easting/northing and zone back to WGS 84 latitude/longitude
Accurately reconstructs lat/long from UTM coordinates
Handles both northern and southern hemisphere inputs
Output compatible with all GPS and mapping systems
Convert coordinates from UTM system to WGS84 (Lat/Long) system
Format: easting northing zone hemisphere (e.g. 449062.43 4418493.12 50 N)
Enter the easting and northing in meters, the zone number (1-60), and select the northern or southern hemisphere — one coordinate set at a time.
Click Convert and the inverse Transverse Mercator projection is applied on the WGS84 ellipsoid to reconstruct the original geodetic position.
Copy the latitude and longitude in decimal degrees, ready for GPS devices and any mapping tool. The conversion is free, fast, and local to your browser.
AThe same easting/northing pair exists in all 60 zones, so without the zone the position is ambiguous by whole swaths of the globe. The hemisphere flag decides whether northing is measured from the equator (N) or with a 10,000,000 m false northing (S).
AEastings normally run from about 100,000 m to 900,000 m within a zone, with 500,000 m on the central meridian. Northern-hemisphere northings run from 0 at the equator to about 9,328,000 m at 84°N; values far outside these ranges usually indicate a typo or a missing zone digit.
AThe mathematical inversion itself is accurate to millimeters. Real-world limits come from the projection's scale distortion — up to roughly 1:2,500 near zone edges — and from the precision of your source data, not from this tool.
