Latitude and Longitude Finder (GPS Coordinates of Any Place)

What Are My Coordinates?

Press Find My Coordinates above and allow location access. Your latitude and longitude appear at the top of the tool in decimal degrees (for example 40.758000, -73.985500), with DMS, DMM, UTM and the other formats below it, plus the ground elevation and time zone of the point.

• Where the position comes from. The browser's Geolocation API asks your device for a fix. A phone uses GPS and other satellite systems when it can see the sky, and Wi-Fi and cell-tower positioning otherwise; a laptop usually has no GPS and relies on nearby Wi-Fi networks, or only your IP address as a last resort.
• The accuracy circle. The device reports an accuracy radius with each fix, and the map draws it as a circle around the pin. The current W3C specification defines it as a 68% confidence radius (one standard deviation), so your true position is inside it about two times out of three. A radius of 5 to 20 m is typical outdoors on a phone; hundreds of meters or more means the fix came from Wi-Fi or IP data.
• Privacy. Your browser asks before sharing your location, and you can revoke the permission at any time. Open Map Lab does not store your position. To show the street address, elevation and map, the point is sent to OpenStreetMap Nominatim, Open-Meteo and the map tile server.
• Indoors and on a VPN. Indoors, satellite signals are weak and the fix may jump or fall back to Wi-Fi. A VPN does not change GPS, but on a computer without GPS the location can follow the VPN server's IP address to another city or country. If the circle is large, click your real position on the map instead.

You can also paste coordinates you already have, such as 40°45'28.8"N 73°59'07.8"W or 40 45.48 N 73 59.13 W, into the search box: the tool reads DD, DMM and DMS, with signs or N/S/E/W letters, and warns you if the values look swapped.

How Latitude and Longitude Work

Latitude and longitude are angles that locate a point on the WGS84 reference ellipsoid, the model of Earth's shape used by GPS and web maps:

• Latitude (φ): the angle north or south of the Equator (0°). The North Pole is +90° (90° N) and the South Pole is −90° (90° S). Lines of constant latitude are called parallels; they never intersect.
• Longitude (λ): the angle east or west of the prime meridian (0°), which the 1884 International Meridian Conference placed at the Royal Observatory in Greenwich, England. (The WGS84 zero meridian used by GPS runs about 100 m east of the historic Greenwich line.) Longitude runs from 0° to +180° east and 0° to −180° west, meeting at the 180th meridian, which the International Date Line mostly follows. Lines of constant longitude are called meridians; they converge at the poles.

Reading a coordinate in degrees, minutes and seconds

A degree is split into 60 minutes (′) and a minute into 60 seconds (″). The letter at the end tells you the hemisphere, which becomes the sign in decimal degrees: north and east are positive, south and west negative.

One Point in Every Coordinate Format

The same spot, Times Square, New York City, written in each format the tool can copy. All values below are generated by the same conversion code as the tool, so they match what you get when you load that point.

To convert a coordinate you already have, use the GPS coordinate converter.

How Many Decimal Places Do You Need? (Table)

A common question in GPS navigation and web development is: “How many decimal places do I actually need?” Five decimal places (about 1 m) already match the best a phone can do; storing 10 or 12 decimals only records noise.

Why a degree of longitude shrinks toward the poles

Meridians converge at the poles, so the east-west distance covered by one degree of longitude falls from about 111 km at the equator to zero at the poles. That is why the same number of decimal places is more precise east-west in Oslo than in Singapore.

How to Get Coordinates in Google Maps, Apple Maps, iPhone and Android

Every major map app can show the latitude and longitude of a point. Menus change between app versions, so the wording may differ slightly on your device.

Common Coordinate Mistakes

Latitude and Longitude of Famous Landmarks

Coordinates of 57 well-known places in decimal degrees (WGS84, 4 decimals, about 11 m), grouped by continent. Each point is the landmark itself (the summit for mountains), not an entrance or visitor center. Select a name to load it in the tool above with its DMS, UTM, elevation and time zone.

US State Capitals: Latitude and Longitude

Latitude and longitude of all 50 state capitals. Each value is the U.S. Census Bureau's internal point for the capital city (2024 Gazetteer), a point inside the city limits, not the capitol building. In large or oddly shaped cities such as Juneau, Phoenix or Oklahoma City it can be several kilometers from downtown. Census coordinates use NAD83, which agrees with WGS84 to within about 1 to 2 m in the contiguous US, far below the 4-decimal rounding.

Hemispheres and Opposite Points

An antipode is the point diametrically opposite your position on the globe. If you drilled a straight tunnel through the center of the Earth, you would come out at your antipodal coordinates.

Because oceans cover about 71% of the planet, most land has an antipode in the ocean. Only about 4% of Earth's surface is land with land directly opposite it (such as parts of New Zealand and Spain, or eastern China and northern Argentina).

Calculation: Finding the Opposite Point

Finding an antipode requires flipping the latitude sign and shifting longitude by 180 degrees:
