A coordinate converter that reads any format you paste
GPS receivers, survey plans, hiking apps, military grids and Google Maps all write the same place differently. This coordinate converter takes whatever you have — decimal degrees, degrees-minutes-seconds, degrees and decimal minutes, a UTM grid reference, an MGRS string, a geohash or a Plus Code — detects the format automatically and shows the location in every other format at once, with a dot on a world map so you can see at a glance that the hemisphere and zone are right.
The Taj Mahal is loaded as the example: 27.1751, 78.0421 in decimal degrees is 27°10′30.4″N 78°02′31.6″E in DMS, 44R 206911 E 3009287 N in UTM, 44RKR0691009286 in MGRS, tsz6xghd2 as a geohash and 7JVW52GR+2RX as a Plus Code. Batch mode converts a whole list — one coordinate per line, formats mixed freely — into a table you can download as CSV for a spreadsheet, GIS package or route map.
Everything is computed in your browser on the WGS84 ellipsoid; no coordinates are sent to a server.
How to use the Coordinate Converter
- Paste or type a coordinate into the input. The line under it shows which format was detected.
- Read the location in every format in the list on the left; press the copy icon next to any line, or Copy all formats to copy the whole block.
- Adjust the precision — decimal places for degrees, seconds decimals for DMS, and the geohash/Plus Code length — to match what your receiver or document uses.
- Check the dot on the map: a wrong hemisphere letter or swapped latitude/longitude is obvious there.
- For many points, switch to Batch, paste one per line, press Convert all and download the CSV.
Coordinate Converter features
Format auto-detection
Decimal degrees with signs or N/S/E/W letters, DMS and DDM with symbols or plain spaces, UTM with a band letter or hemisphere, MGRS with or without spaces, geohash and full Plus Codes.
UTM and MGRS on WGS84
Projection uses the Krüger series (the same formulation as modern GIS libraries), accurate to the millimetre within a zone, with the Norway and Svalbard zone exceptions and the AA 100 km letter scheme for MGRS.
Geohash and Plus Codes
Encode at any length from 4 to 12 characters (geohash) or 10–11 characters (Plus Code) and decode to the cell centre, with the cell size shown so you know the precision of what you were given.
Map check
The point is drawn on an embedded world map so the continent and hemisphere are obvious at a glance.
Batch to CSV
Convert hundreds of mixed-format lines at once and download every format as a CSV file.
The formats, side by side
| Format | Example (Taj Mahal) | Where you meet it |
|---|---|---|
| Decimal degrees (DD) | 27.1751, 78.0421 | Web maps, GPX files, APIs, phones. North and east are positive. |
| Degrees, minutes, seconds (DMS) | 27°10′30.4″N 78°02′31.6″E | Charts, older documents, Wikipedia infoboxes. |
| Degrees, decimal minutes (DDM) | 27°10.506′N 78°02.526′E | Marine and aviation GPS units, geocaching. |
| UTM | 44R 206911 E 3009287 N | Topographic maps and surveying: metres east and north inside a 6° zone. |
| MGRS | 44RKR0691009286 | Military and emergency services: UTM compressed into one string with 100 km square letters. |
| Geohash | tsz6xghd2 | Databases and APIs: each extra character divides the cell by 32. |
| Plus Code | 7JVW52GR+2RX | Google Maps addresses for places without street addresses. |
How the conversions work
DD, DMS and DDM are the same number written three ways: 27.1751° is 27° plus 0.1751 × 60 = 10.506′, which is 10′ plus 0.506 × 60 = 30.4″. Rounding happens only at the final step, so a DMS value converts back to the original decimal.
UTM projects the ellipsoid onto 60 transverse Mercator zones, each 6° of longitude wide, with a scale factor of 0.9996 on the central meridian, a false easting of 500,000 m and, in the southern hemisphere, a false northing of 10,000,000 m. The latitude band letter (C–X, 8° each, with I and O skipped) tells you the hemisphere; the tool also accepts a plain N or S. MGRS adds two letters that name the 100 km square and then drops the leading digits, so 44RKR0691009286 is 44R 206910 E 3009286 N (MGRS truncates the metres; the UTM line above is rounded).
A geohash interleaves bits of longitude and latitude and writes them in base 32; a Plus Code does the same idea in base 20 with a 4 × 5 refinement grid after the tenth character. Both describe a cell, not a point, which is why decoding returns the centre and the ± size.
Common mistakes this converter catches
- Swapped latitude and longitude. Any value over 90 cannot be a latitude; the parser rejects it and tells you.
- Wrong hemisphere. A missing minus sign or S/W letter mirrors the point — the map dot makes this obvious.
- Short Plus Codes. “52GR+2R” only works with the city it was written for; paste the full code (with the four-character area prefix) instead.
- MGRS with an odd number of digits. Easting and northing must have the same number of digits (2, 4, 6, 8 or 10 in total).
- Datum mix-ups. This tool is WGS84 only. References on older national datums (Everest, OSGB36, NAD27) can be hundreds of metres off and need a datum transformation first.
Coordinate Converter FAQ
How do I convert DMS to decimal degrees?
Paste the DMS value (for example 27°10′30″N 78°02′32″E, or just 27 10 30 N 78 2 32 E) and read the Decimal degrees line. The formula is degrees + minutes/60 + seconds/3600, negative for south and west.
Can this coordinate converter turn UTM into latitude and longitude?
Yes. Enter the zone, the band letter or hemisphere, then easting and northing — for example 44R 206911 3009287 or 56 S 334000 6251000 — and the converter returns WGS84 latitude and longitude plus every other format.
What is the difference between UTM and MGRS?
They are the same projection. MGRS writes the zone and band, two letters for the 100 km square, then the remaining easting and northing digits. The converter translates between the two exactly.
How accurate are the conversions?
DD, DMS and DDM are exact apart from rounding. UTM and MGRS use the Krüger series, accurate to better than a millimetre inside a zone. Geohash and Plus Code decoding returns the cell centre, with the cell size shown.
Which datum does it use?
WGS84, the datum used by GPS, Google Maps, OpenStreetMap and most modern data. Coordinates on older local datums should be transformed before using them here.
Is my location data uploaded?
No. Parsing, projection, the map and the batch CSV all run in your browser; nothing is sent to a server.
