Mapping & survey

Coordinate Converter

Convert between decimal degrees, DMS and UTM — paste either format in.

Enter latitude and longitude as decimal degrees (37.9838) or DMS (37°59'01.68"N) — either format works in either field.

Converted coordinates

Decimal: 37.983800, 23.727500

DMS: 37°59'1.68"N 23°43'39.00"E

UTM: Zone 34N739542.0 E, 4207528.1 N

UTM uses the standard WGS84 Transverse Mercator projection — the same reference ellipsoid most GPS devices and GIS software use.

How it works

Type or paste a latitude and longitude in either decimal degrees or DMS format — the converter detects which one you used automatically. Results show all three common formats: decimal degrees, DMS, and UTM (Universal Transverse Mercator), using the standard WGS84 ellipsoid.

Limitations

UTM coordinates are zone-based — always note the zone number and hemisphere alongside the easting/northing, since the same easting/northing pair means a different place in a different zone.

Different devices and software default to different formats — most GPS receivers show decimal degrees or DMS, while surveying and GIS software often uses UTM. This tool converts between all three so you can match whatever your other tools expect.
