Lat Long to UTM Converter
Convert a WGS84 latitude/longitude coordinate into UTM (Universal Transverse Mercator) zone, easting, and northing.
How latitude/longitude converts to UTM
The Universal Transverse Mercator (UTM) system divides the Earth into 60 north-south zones, each 6 degrees of longitude wide, and projects coordinates within each zone onto a flat grid measured in meters (easting and northing) rather than degrees. This makes UTM convenient for distance and area calculations that decimal degrees don’t support directly.
This calculator uses the standard Transverse Mercator projection formulas (based on the WGS84 ellipsoid, the same reference system used by GPS) to compute the UTM zone number, easting, and northing for a given latitude and longitude. A scale factor of 0.9996 and a 500,000 meter false easting are applied per the standard UTM definition, and 10,000,000 meters is added to the northing for locations in the southern hemisphere.
This tool is intended for general mapping, GIS, and educational purposes. For surveying-grade or legal coordinate work, use certified geodetic software and datum information specific to your project.
