What is the difference between decimal degrees and DMS?

Decimal Degrees (DD) express latitude and longitude as a single decimal number, e.g. 40.7589. Degrees Minutes Seconds (DMS) break this down into 40° 45' 32” N — the traditional surveying format. Both describe the same location; DD is more common in digital tools, DMS in fieldwork.

What is UTM used for?

Universal Transverse Mercator (UTM) is a metric coordinate system widely used in topographic mapping, land surveying, and GIS. It divides the Earth into 60 zones and provides easting/northing values in meters, making distance calculations straightforward.

MGRS (Military Grid Reference System) is used by NATO militaries and some GIS applications. It builds on UTM by adding a 100 km grid square identifier using two letters, resulting in compact references like 18TWL8562812497.

A Geohash encodes a geographic location into a short alphanumeric string using a base32 encoding. Longer Geohash strings are more precise (8 chars ≈ 19m accuracy). They are commonly used in databases for proximity queries.

How do I get GPS coordinates from Google Maps?

Right-click any location on Google Maps and the decimal degrees coordinates appear at the top of the context menu (e.g. 40.758900, -73.985100). Click them to copy, then paste into this converter.

About the GPS Coordinate Converter

GPS coordinates come in several formats depending on the device, software, or region. This tool automatically detects and converts between Decimal Degrees, DMS, UTM, MGRS, and Geohash formats.

Decimal Degrees vs. DMS

Decimal Degrees (DD) expresses latitude and longitude as a single decimal number (e.g. 40.7589). It's the format used by most GPS apps, Google Maps, and mapping APIs.

Degrees Minutes Seconds (DMS) expresses coordinates as degrees, minutes, and seconds (e.g. 40°45'32"N). It's traditionally used in navigation, surveying, and older mapping systems.

Format	Example	Common Use
Decimal Degrees	40.758900, -73.985100	GPS apps, web maps, APIs
Degrees Minutes Seconds	40°45'32"N 73°59'06"W	Navigation, surveying
UTM	18T 585628 4511322	Military, engineering, GIS
MGRS	18TWL8562811322	Military grid reference
Geohash	dr5regw3p	Location-based databases, URLs

UTM and MGRS Formats

UTM (Universal Transverse Mercator) divides the world into zones and expresses position as an easting/northing pair in meters — useful for precise distance and area calculations over large regions.

MGRS is a military standard built on UTM, expressing position as a compact alphanumeric grid reference commonly used in tactical and emergency response contexts.

Frequently Asked Questions

What GPS coordinate formats are supported?

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

How do I convert DMS to decimal degrees?

Paste your DMS coordinates (e.g. 40°45'32"N) into the converter and it automatically detects the format and shows the decimal degree equivalent.

What's the difference between UTM and MGRS?

MGRS is built on top of the UTM coordinate system but uses a more compact alphanumeric grid reference, commonly used in military and emergency response applications.

Why do my coordinates show as 'unrecognized'?

Check that you've included both latitude and longitude, and that the format matches one of the six supported types. Try a well-known example format if unsure.
