Enter UTM zone, easting and northing — GPSwitch converts to lat/long and 26 other coordinate formats instantly.
Paste your coordinates and convert to all 27 formats instantly.
Open GPSwitch ConverterUTM (Universal Transverse Mercator) is a coordinate system that divides the Earth into 60 zones, each 6° of longitude wide. Within each zone, locations are expressed as easting (distance east of the zone centre line) and northing (distance north of the equator), both in metres.
UTM is the primary coordinate system used in surveying, military mapping, GIS, and topographic map production. A typical UTM coordinate looks like: 31U 448251 5412678 — zone 31U, easting 448251, northing 5412678.
The conversion requires the zone number and letter, then applies the Transverse Mercator projection formulas to recover geographic lat/long. GPSwitch handles all zone identification and projection math — you only need to paste the UTM string. The result is in WGS84 datum, the standard used by GPS and Google Maps.
31U 448251 5412678 — zone + easting + northing31N 448251 5412678 — using N/S hemisphere instead of band letterYou need three values: the zone number (1-60), the zone letter or hemisphere (N/S), the easting in metres, and the northing in metres. Example: 31U 448251 5412678. If you only have easting and northing without the zone, conversion is not possible.
GPSwitch converts to WGS84, the datum used by all civilian GPS devices, Google Maps, and OpenStreetMap. If your UTM data is in a different datum (NAD83, ED50), the result may be offset by a few metres.
Yes. GPSwitch outputs all 27 formats simultaneously. When you paste a UTM coordinate, you get decimal degrees, DMS, MGRS, Geohash, Plus Code, and direct links to Google Maps and Waze — all at once.
