What coordinate formats are supported?

Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM and Geohash.

What datum does this tool use?

WGS84, the standard datum used by GPS satellites and Google Maps worldwide.

Can I paste coordinates in Spanish format (using O for West)?

Yes. The tool accepts both W (West) and O (Oeste) as the western direction indicator.

GPS Coordinate Converter — DD, DMS, UTM, Geohash

This free tool converts geographic coordinates between the most common formats used in GPS receivers, GIS software, and outdoor navigation. All conversions use the WGS84 datum — the standard used by GPS satellites and Google Maps.

Supported Formats

Decimal Degrees (DD) — e.g., 40.7128, -74.0060. Used by Google Maps, REST APIs, and most modern GPS apps. Negative values = South/West.
Degrees Minutes Seconds (DMS) — e.g., 40°42'46"N, 74°0'22"W. Traditional format used in paper maps, aviation, and marine navigation. Accepts W or O (Oeste) for West.
Degrees Decimal Minutes (DDM) — e.g., 40°42.768'N, 74°0.36'W. Used in nautical charts and many Garmin GPS devices.
UTM (Universal Transverse Mercator) — e.g., 18T 583960 4507523. Metric grid used by the military (NATO), surveyors, and topographic maps.
Geohash — e.g., dr5regw3p. Compact alphanumeric encoding used in geospatial databases. 9-char precision ≈ ±2.4 m × ±4.8 m.

Frequently Asked Questions

Does it accept coordinates in Spanish format?

Yes. The tool accepts O (Oeste) as the western direction, which is standard in Spanish GPS devices and maps. For example: 40°18'33"N 3°53'45"O is parsed correctly.

What is the difference between DD and DMS?

Both represent the same position. DD uses a single decimal number per axis (40.7128°N). DMS splits it into degrees, minutes and seconds (40°42'46"N). DD is more common in software; DMS is the traditional cartographic format.

How accurate is the UTM conversion?

The Snyder (1987) formulas used here are accurate to within ~1 mm within a UTM zone. Accuracy degrades slightly near zone boundaries (beyond ±3° from the central meridian).

Can I convert UTM back to latitude/longitude?

Yes. Paste a UTM coordinate such as "18T 583960 4507523" and the tool auto-detects it and outputs DD, DMS, DDM, and Geohash.
