Coordinate Converter (GPS) — Free Online Tool

What Is Coordinate Converter (GPS)?

A free online GPS coordinate converter that converts between Decimal Degrees (DD), Degrees/Minutes/Seconds (DMS), and Degrees/Decimal Minutes (DDM). View UTM zone, easting, and northing for any latitude/longitude. Perfect for GIS professionals, hikers, and surveyors.

GPS coordinates can be expressed in several formats: Decimal Degrees (DD) like 37.7749, Degrees/Minutes/Seconds (DMS) like 37 46 30 N, and Degrees/Decimal Minutes (DDM) like 37 46.5 N. Different applications and devices use different formats — Google Maps uses DD, GPS devices often use DMS, and aviation uses DDM. Coordinate Converter converts between all three formats with UTM zone information.

Select your input format — DD, DMS, or DDM. Enter the latitude and longitude values. For DMS format, separate degrees, minutes, seconds, and direction (N/S/E/W) into the provided fields. Northern and Southern hemispheres are supported for latitude, Eastern and Western for longitude. The conversion results display instantly in all three formats.

The UTM (Universal Transverse Mercator) section shows the UTM zone number (based on longitude), the easting and northing values, and the hemisphere. UTM divides the world into 60 zones of 6 degrees each. Zone 1 starts at 180°W. For example, New York City is in UTM zone 18N.

Each format result can be copied individually with a click. The conversion is particularly useful for GIS professionals switching between mapping platforms, hikers reading coordinates from different sources, and surveyors working with multiple coordinate systems.

Real-World Use Cases for Coordinate Converter (GPS)

Converting DMS Coordinates from a GPS Device to DD for Google Maps

Your GPS device shows a waypoint as N 40 45 30 W 73 59 15. Select DMS input, enter these values. The DD result shows 40.7583, -73.9875. Copy the DD coordinates and paste them into Google Maps to see the location. The DDM result is also shown for reference.

Converting Decimal Degrees to DMS for a Hiking Map

A hiking website provides trailhead coordinates in DD: 44.0521, -121.3140. Select DD input, enter the values. The DMS result shows N 44 3 8, W 121 18 50. Write these DMS coordinates on your physical map. The UTM zone is 10T with northing and easting values for grid-based navigation.

Finding the UTM Zone for a Survey Point

A surveyor needs UTM coordinates for a plot at 34.0522, -118.2437 (Los Angeles). Enter DD, the UTM display shows Zone 11S with easting and northing. The three coordinate formats are also shown for the survey report.

Pro Tips for Coordinate Converter (GPS)

1Always verify the hemisphere (N/S for latitude, E/W for longitude). A missing or incorrect direction sign will place the coordinate on the opposite side of the equator or prime meridian.
2UTM zones are 6 degrees wide. Zone 1 covers 180°W to 174°W, and zone 60 covers 174°E to 180°E. Your zone is floor((longitude + 180) / 6) + 1.
3DD format is preferred for digital mapping and APIs. DMS format is traditional for paper maps and land surveying. DDM is common in aviation.
4The same location can have slightly different DMS values depending on the datum used (WGS84, NAD83, etc.). This converter uses WGS84, the standard GPS datum.

Coordinate Converter (GPS) — Frequently Asked Questions

What coordinate formats are supported?

Decimal Degrees (DD), Degrees/Minutes/Seconds (DMS), Degrees/Decimal Minutes (DDM), and UTM zone information.

Is the UTM calculation precise?

UTM zone is calculated based on longitude. Easting and northing are approximations suitable for general reference.

How accurate are the unit conversions?

Conversions use NIST-standard conversion factors with precision up to 15 significant digits. Currency exchange rates update every 10 minutes from a free data source.

Can I convert between any two units?

Yes. Each converter supports all standard units within its category. For example, the length converter handles metric, imperial, and nautical units.

Is Coordinate Converter (GPS) really free to use?

Yes, Coordinate Converter (GPS) is completely free with no hidden charges, no usage limits, and no premium tiers. You can use it as often as you need without signing up or providing any personal information.
