WGS 84 Latitude/Longitude to UTM Coordinate Converter

Convert decimal latitude and longitude on the WGS 84 ellipsoid to a Universal Transverse Mercator grid coordinate, or reverse a WGS 84 UTM coordinate to decimal degrees. A complete UTM position requires zone, hemisphere, easting, northing, and datum. UTM divides the world from 80 degrees south to 84 degrees north into 60 longitudinal zones, normally six degrees wide. Automatic selection uses the standard longitude zone and applies the Norway and Svalbard exceptions. Each zone uses an ellipsoidal Transverse Mercator projection with a central scale factor of 0.9996, a false easting of 500,000 metres, and a 10,000,000 metre false northing in the Southern Hemisphere. Easting and northing values are metres within a projected zone; the same numeric pair can identify different places in another zone, hemisphere, or datum. Hemisphere N or S is not the same as a latitude-band letter. Hemisphere controls false northing and the projected coordinate reference system. Latitude-band letters C through X provide separate grid-reference context; band N does not mean the entire Northern Hemisphere. The result includes the applicable WGS 84 UTM EPSG code from EPSG:32601 through EPSG:32660 in the Northern Hemisphere or EPSG:32701 through EPSG:32760 in the Southern Hemisphere. Values stay in the browser. Analytics retain only bounded action, conversion direction, and automatic-or-override status—never latitude, longitude, easting, northing, zone, hemisphere, band, EPSG code, datum, project, location, notes, or copied result. This is projection and inverse projection on WGS 84 only. It does not transform NAD27, NAD83, ETRS89, another datum realization, an epoch-dependent coordinate, a local mine grid, or height. A datum transformation requires a verified source coordinate reference system, suitable operation, area of use, realization, and sometimes coordinate epoch. UTM does not cover the poles; use Universal Polar Stereographic or another appropriate system outside 80 degrees south to 84 degrees north. A manual nearby zone may support an established cross-boundary project specification, but forcing a remote zone is rejected because distortion and series error grow away from the central meridian. The tool does not calculate MGRS, UPS, grid convergence, point scale, geoid separation, orthometric height, uncertainty, or tectonic motion. Do not use an unaudited browser conversion as

Common questions

What is a UTM coordinate?
Universal Transverse Mercator divides most of Earth between 80 degrees south and 84 degrees north into 60 longitudinal zones. A position uses a zone, hemisphere, easting, and northing in metres.
How does the converter choose a UTM zone?
Automatic mode uses the six-degree longitude zone and applies the standard Norway and Svalbard exceptions. A nearby manual zone can support defined cross-boundary project continuity.
Is UTM hemisphere the same as a latitude band?
No. Hemisphere N or S controls false northing and the projected coordinate reference system. Letters C through X are separate latitude-band designators used in grid references.
Does this transform NAD27, NAD83, ETRS89, or another datum to WGS 84?
No. It projects and unprojects coordinates on the WGS 84 ellipsoid only. Datum transformation requires the correct realization, area of use, transformation, and sometimes coordinate epoch.
Can I use this outside the UTM latitude limits?
No. UTM conventionally covers 80 degrees south through 84 degrees north. Polar positions require Universal Polar Stereographic or another suitable coordinate reference system.
