Details
DD - Decimal Degrees 40.7128, -74.0060 Google Maps, GPS devices, most mapping apps Read
Decimal Degrees (DD) is the most common GPS coordinate format. It represents latitude and longitude as decimal numbers. Positive values indicate north latitude and east longitude, while negative values indicate south and west.
DMS - Degrees Minutes Seconds 40°42'46"N 74°00'21"W Aviation, nautical charts, cartography Read
DMS writes coordinates as degrees, minutes, and seconds with direction letters. It is widely used in aviation and nautical coordinate workflows.
DDM - Degrees Decimal Minutes 40°42.767'N 74°00.358'W Marine navigation, geocaching, hiking GPS Read

UTM - Universal Transverse Mercator 18T 583960 4507523 Military, surveying, topographic maps Read
UTM divides Earth into 60 zones and expresses location in meters as easting and northing. It is practical for surveying and engineering coordinate work.
MGRS - Military Grid Reference System 18TWL8395907523 NATO forces, emergency services, SAR Read
MGRS extends UTM with grid square identifiers for compact references. It is used for military and emergency coordinate operations.
Plus Code - Google Plus Code 87G7PX7V+4H Address-less areas, delivery services Read
Plus Codes are open location codes that represent places without formal addresses. They are useful for delivery and field coordinates.
Geohash - Geohash dr5regw3pg Database indexing, spatial queries, dev tools Read
Geohash encodes coordinates into a compact base32 string. Nearby locations share prefixes, which helps with spatial indexing and nearby coordinate search.

Common Coordinate Conversion Examples
Reference examples for popular coordinate conversions used in GPS, GIS, surveying, and map workflows.
DD -> DMS Conversion
Multiply the decimal part by 60 to get minutes, then multiply fractional minutes by 60 for seconds. Add N/S and E/W direction.
40.7128 -> 40d 42m 46s N UTM -> Lat/Long
Identify UTM zone number and letter, then apply inverse Transverse Mercator projection to get geographic coordinates.
18T 583960 4507523 -> 40.71N, 74.01W MGRS -> Lat/Long
MGRS combines a grid zone, 100 km square identifier, and numeric easting/northing pair for compact location references.
18TWL8395907523 -> 40.7128N Address -> Coordinates
Address geocoding converts a place name or postal address into latitude and longitude for map and data workflows.
Times Square, NYC -> 40.7580N, 73.9855W GCJ-02 -> WGS-84
GCJ-02 is the offset coordinate system used by major Chinese map platforms and differs from standard WGS84 GPS coordinates.
39.9087N, 116.3975E -> 39.9073N, 116.3913E Geohash -> Lat/Long
Geohash encodes latitude and longitude into a short base32 string whose shared prefixes indicate geographic proximity.
dr5regw3pg -> 40.7128N, 74.0060W Frequently Asked Questions
Common questions about our online coordinate converter, supported formats, and GPS workflows.
What is a coordinate converter?
CoordConv is a browser-based coordinate converter that helps you convert coordinates between common geographic formats such as Decimal Degrees, DMS, DDM, UTM, MGRS, Plus Code, and Geohash.
How accurate is this converter?
CoordConv provides up to 6 decimal places of precision, approximately +/-0.11 meters. This is sufficient for most mapping and surveying coordinate tasks.
What coordinate formats are supported?
CoordConv supports 7 formats: DD, DMS, DDM, UTM, MGRS, Plus Code, and Geohash. This online coordinate converter is built for common GPS, GIS, and map coordinate workflows.
What is the difference between DD, DMS, and DDM?
CoordConv lets you compare DD, DMS, and DDM as different notation styles for the same location. DD is decimal notation, DMS uses degrees-minutes-seconds, and DDM uses degrees with decimal minutes.
What is UTM and when should I use it?
CoordConv supports UTM, a zone-based coordinate system with meter-based positions that is useful for surveying, engineering, and topographic workflows.
What is MGRS and who uses it?
CoordConv supports MGRS, a compact military grid format based on UTM that is widely used in defense, emergency response, and search-and-rescue workflows.
Do I need to create an account?
CoordConv is free and requires no account. Coordinate conversion runs directly in your browser.
Can I convert multiple coordinates at once?
Yes. The Batch Coordinate Converter lets you convert multiple coordinate rows from pasted tables or CSV files in one browser-based workflow.
What datum does this converter use?
We use the WGS84 datum, the global standard used by GPS and major mapping platforms for coordinates.
Why do GPS coordinates show offset on Chinese maps?
Chinese mapping products may use GCJ-02 or BD-09 instead of standard WGS84 coordinates. CoordConv does not currently provide a dedicated GCJ-02 converter, so you should verify the source coordinate system before using those results operationally.
How do I find GPS coordinates on Google Maps?
Find coordinates on Google Maps by right-clicking a point on desktop, or long-pressing to drop a pin on mobile.
What is the difference between WGS84 and NAD83?
WGS84 and NAD83 are geodetic datums with small differences for most practical coordinate use.
