Latitude & Longitude Finder
Enter any address, city or landmark to get its exact latitude and longitude coordinates in decimal degrees and DMS.
This page explains how the latitude & longitude finder works, the data and formulas behind it, and how to interpret the result. Geocoding is the foundation of every map application. Every time you search for a place in Google Maps, you are using a geocoder. Nominatim is the open-source geocoder from OpenStreetMap, free and covering the entire world. The tool is one of 329 free, open tools on JoseFitani for maps and geography. It runs in your browser with no sign-up needed. Use the search field or click the map to drop a pin - the tool uses Nominatim reverse geocoding on OpenStreetMap data and returns the result in seconds. Below you'll find a step-by-step guide, real use cases, the methodology, FAQs, and data sources.
Click anywhere on the map to get its coordinates and the nearest address (reverse geocoded via OpenStreetMap).
How to use this tool
Type your query, paste coordinates, or click on the map. The tool uses Nominatim reverse geocoding on OpenStreetMap data to process your input locally in the browser.
The result appears instantly with the map showing your location. You can adjust by clicking elsewhere or searching a new place.

What people use this tool for
Hikers heading beyond mobile coverage need the trailhead coordinates saved in their GPS before they lose signal. Looking up the car park or trail start in advance means the device can navigate to the exact point even with no data connection on the mountain.
Photographers organising large archives add coordinates to images so they can search by location years later. Looking up each shooting location once, at cataloguing time, embeds a permanent geographic record in the metadata.
Friends meeting at large venues waste time when everyone navigates to a different entrance. Sharing the latitude and longitude of one specific gate drops every person's map pin on the same spot, eliminating the where-are-you phone calls.
Citizen scientists and researchers logging wildlife sightings, plant specimens, or geological features need coordinates attached to each record. A quick lookup converts a named location into the decimal degrees that databases and mapping tools expect.
How it's calculated
Geocoding converts human-readable addresses into geographic coordinates using a global gazetteer.
The calculation runs in your browser - no data is sent to our servers. Map tiles come from OpenStreetMap (ODbL license), geocoding uses Nominatim (1 request/second limit), and elevation uses the Open-Elevation API backed by SRTM data. All are free, open services.
All calculations use the WGS84 datum (EPSG:4326), the same as GPS. For other datums (NAD27, NAD83, ETRS89), a separate conversion is needed. The difference is typically under 1 metre - negligible for most uses but important for survey-grade work.
The formulas match those in professional GIS software (QGIS, ArcGIS, Global Mapper), just in a browser-friendly form. For sub-metre accuracy, use professional software with ellipsoidal calculations. Results are shown in multiple units: km and miles for distance, km²/m²/hectares/acres for area, metres and feet for elevation. Conversion factors are exact (1 mile = 1.609344 km), so the only error source is input precision.

Frequently asked questions
How accurate are coordinates?
City centers are accurate to ~100 m; precise addresses to ~10 m.
What is the difference between decimal degrees and DMS?
Decimal degrees express a coordinate as a single number, like 48.8584, which computers and APIs handle easily. DMS splits the same position into degrees, minutes, and seconds, like 48 degrees 51 minutes 30 seconds, which is the traditional format printed on paper maps. The tool shows both so you can use whichever your task requires.
How precise are the coordinates it returns?
Geocoding usually resolves to the address or building level, accurate within tens of metres. For a landmark, the result is a representative point, such as the main entrance or centre, rather than every corner of the site. That is plenty for navigation and tagging, but not for surveying.
Does the coordinate finder need an internet connection?
Yes. Turning a place name into coordinates is called geocoding, and it queries an online gazetteer database that lives on a server. Without a connection the search cannot run. The coordinate display and format conversion need no connection, but the initial lookup does.
Why do I get several results for one place name?
Many place names are reused around the world: there are dozens of Springfields, Richmonds, and San Joses. The tool lists the matches it finds so you can pick the right country and region. Always check the suggested location details before accepting a result.
Can I search using the local-language name?
Usually yes, and it often works better. If the English name returns nothing useful, try the local spelling, such as Munchen for Munich or Firenze for Florence. Gazetteers index local names thoroughly, though transliteration variants can still trip up the search.
What do negative coordinates mean?
Negative latitude means south of the equator, and negative longitude means west of the prime meridian. Sydney, for example, sits at about -33.87 latitude, 151.21 longitude: south of the equator but east of Greenwich. The minus sign is simply the hemisphere encoded numerically.
Can I paste the coordinates into Google Maps?
Yes. Paste decimal degrees directly into the search box, for example 48.8584, 2.2945, and the map drops a pin at that exact point. This works in most mapping apps and is the quickest way to share a precise location with someone else.
Why is the pin slightly off the actual building?
Geocoders return the best point their database holds, which may be a rooftop centroid, a street interpolation, or an older surveyed point. Offsets of 10 to 50 metres are normal and harmless for navigation. If you need the exact doorway, stand there with a GPS instead.
