Tools Coordinates

Latitude and Longitude Finder

Search a place or click the map. The coordinates come back in every format you might be asked for, ready to copy.

How to use it

  1. Type a place name or address and pick it from the list, or click anywhere on the map, or use your location.
  2. Read the coordinates in decimal degrees, DMS, DDM, geohash, Plus Code, UTM and MGRS, each with a copy button.
  3. Drag the pin to fine-tune the point. The hemisphere, the distance from the equator and the prime meridian, and the antipode update live.

How it works

Places are found with Photon (OpenStreetMap search). Everything else is computed in the browser: the format conversions, the geohash and Plus Code encodings, the UTM projection on WGS84, and the great-circle distances to the equator and the prime meridian using a mean Earth radius of 6,371 km.

Clicking the map gives the coordinate of the click on the map tiles, which are drawn in Web Mercator on WGS84. The place name shown for a click comes from a reverse geocode and is the nearest named feature, not a boundary test.

Questions

Which format should I use?
Decimal degrees for anything digital (spreadsheets, GPS apps, Google Maps). DMS for paper charts and legal descriptions. DDM for aviation and marine GPS units. UTM or MGRS for surveying and land navigation.
How many decimal places do I need?
Four decimals place a point within about 11 m, five within about 1 m, six within about 11 cm. The tool shows six; more digits than that do not mean more accuracy.
What is the antipode line?
The point exactly opposite on the globe: latitude flipped in sign, longitude shifted by 180 degrees. The link opens it in the antipode finder.
