UTM Converter
Convert between WGS84 latitude/longitude and UTM (zone, easting, northing) — the meters-based coordinate system used in surveying, GIS, and topographic maps.

What This Tool Does
- The UTM zone, hemisphere, easting, and northing for any latitude/longitude.
- The WGS84 latitude/longitude for any UTM coordinate.
- Results computed with standard WGS84 transverse Mercator formulas.
Common Use Cases
- Converting GPS coordinates into the UTM values a survey drawing, GIS shapefile, or topographic map expects.
- Reading a UTM grid reference off a paper map and turning it into coordinates you can paste into Google Maps or a GeoJSON file.
- Cross-checking a UTM value from field equipment against a known latitude/longitude.
How It Works
- Lat/Lon → UTM: enter a latitude and longitude — the UTM zone, hemisphere, easting, and northing are computed instantly.
- UTM → Lat/Lon: enter a zone, hemisphere, easting, and northing to get the equivalent WGS84 coordinates.
- Conversion uses the standard WGS84 transverse Mercator projection formulas, computed entirely client-side.
Related Geographic Concepts
- UTM zone
- One of 60 north-south bands, each 6° of longitude wide, that the UTM system divides the world into — the zone number comes entirely from longitude.
- False easting/northing
- UTM adds 500,000 m to easting (and, in the southern hemisphere, 10,000,000 m to northing) so coordinates within a zone never go negative.
FAQ
What is UTM?
Universal Transverse Mercator (UTM) divides the world into 60 numbered zones, each 6° of longitude wide, and expresses a position within a zone as an easting and northing in meters — the flat, meters-based coordinate system many GIS, survey, and military workflows use instead of latitude/longitude.
How do I know which UTM zone a coordinate is in?
The zone number is determined by longitude alone (each 6°-wide band gets the next zone number, starting at 180°W). This tool computes it automatically when converting from latitude/longitude — you only need to supply the zone yourself when converting the other direction, from a UTM coordinate you already have.
What datum does this converter use?
WGS84 — the same datum GPS and virtually all modern web maps use, so results line up with Google Maps, GeoJSON, and GPX coordinates without a separate datum transformation.
Why is my northing a 7-digit number in the southern hemisphere?
UTM adds a 10,000,000 m "false northing" to southern-hemisphere coordinates so northing never goes negative — a value like 6,251,000mN in the southern hemisphere is normal, not an error.
