Supported coordinate formats
- Decimal Degrees (DD)
- The most common format, e.g. 48.8584, 2.2945. Compact and easy to store in spreadsheets, databases, and URLs.
- Degrees Minutes Seconds (DMS)
- The traditional format shown on paper maps, e.g. 48°51'30.2"N 2°17'40.2"E. Each degree is split into 60 minutes and each minute into 60 seconds.
- Degrees Decimal Minutes (DDM)
- Used in marine and aviation navigation, e.g. 48°51.504'N 2°17.670'E. Degrees and minutes, with minutes expressed as a decimal.
- UTM
- A metric grid: zone, easting, and northing in metres. Preferred for surveying and GIS where you need measurements in metres.
- Geohash
- A short base32 string that encodes a location into a grid cell. Useful for indexing, proximity search, and databases.
- Plus Code
- Google's Open Location Code — a short code that works as an address for places without street addresses.
Frequently asked questions
- How do I convert DMS to decimal degrees?
- Paste your DMS value (for example 40°26'46"N 79°58'56"W) into the converter. It instantly returns the decimal degrees equivalent, which you can copy with one click. The formula is decimal = degrees + minutes/60 + seconds/3600, negated for S and W.
- What coordinate formats does this tool support?
- It reads decimal degrees, degrees-minutes-seconds (DMS), degrees-decimal-minutes (DDM), geo: URIs, and Google or Apple Maps links. It outputs Decimal, DMS, DDM, UTM, Geohash, and Plus Code (Open Location Code).
- What is UTM and when should I use it?
- Universal Transverse Mercator (UTM) expresses a location as a zone plus easting/northing in metres. It is widely used in surveying, GIS, and military mapping because distances on the grid are in metres rather than degrees.
- Are the conversions accurate?
- Yes. UTM uses the WGS84 ellipsoid with the standard Transverse Mercator series (sub-metre accuracy), and Plus Codes follow Google's Open Location Code specification.
