Lat/Lng Coordinate Converter

Universal Transverse Mercator (UTM) is a projected coordinate system that divides the Earth into 60 longitudinal zones. Within each zone, positions are expressed in metres eastward (easting) and northward (northing) from a zone origin.

WGS84 is a geographic coordinate system using degrees of latitude and longitude on the Earth's surface. UTM is a projected system using metres on a flat plane — each zone is a separate Mercator projection.

UTM zones are 6° wide. Zone 1 starts at 180°W. The tool automatically determines the correct zone from the longitude of your input coordinates.

Yes. GPS receivers output WGS84 decimal degrees. Use this tool to convert them to UTM metres for use with surveying equipment or in datasets that use UTM.

The mathematical transformation is reversible and precise. Round-trip conversion (WGS84 → UTM → WGS84) returns coordinates identical to the original within floating-point precision.
