Latitude/Longitude to UTM Converter
Type a latitude and longitude — or tap Use my location — to read off the UTM zone, hemisphere, easting and northing, the flat metre grid that surveyors prefer over angles. The reverse section takes a UTM reference and hands back decimal degrees and DMS. It all happens in the page.
How to convert lat/long to UTM
- Enter a latitude and longitude in the box, e.g.
40.7128, -74.0060. Signed decimals or hemisphere letters (N/S/E/W) both work. - Or tap Use my location to drop in your current GPS position — your browser asks permission first and the result stays on your device.
- Read off the zone number and band letter, the hemisphere, and the easting and northing in metres. Each value has a copy button.
- Drag the map marker or tap a new spot to fine-tune — the input and every UTM value update together.
- To go the other way, scroll to the reverse section and type a zone, band letter, easting and northing to get the lat/long back.
What the UTM parts mean
| Part | Example | What it is |
|---|---|---|
| Zone number | 18 | One of 60 six-degree-wide longitude zones, numbered 1–60 from the antimeridian eastward. |
| Band letter | T | The MGRS latitude band (C–X, skipping I and O), each 8° tall. It also tells you the hemisphere. |
| Hemisphere | N | North or South. UTM uses a false northing of 10,000,000 m for the southern hemisphere. |
| Easting | 583959 | Metres east within the zone, measured from a false origin (500,000 m at the central meridian). |
| Northing | 4507351 | Metres north of the equator (or from the false southern origin in the southern hemisphere). |
Accuracy, datums and the UTM range
UTM is a metric grid laid over the Transverse Mercator projection, so inside one zone the easting and northing behave like flat X/Y metres — exactly what surveying, GIS and field work want. This tool resolves every figure on the WGS84 datum using a Krüger series good to a few millimetres, then settles eastings and northings to whole metres. UTM is defined only between about 80°S and 84°N; past that band the projection breaks down and the tool reports out of range rather than return a wrong value. Source data tied to a different datum — an older national grid, for instance — can land tens of metres off, so confirm what the receiving system expects. To read the same point in other notations, open the coordinate converter; for the military grid, see lat/long to MGRS.
