GPS Coordinate Converter — Address ↔ DD ↔ DMS
Convert between an address, decimal degrees (DD) and degrees-minutes-seconds (DMS) instantly, for free, in your browser — no sign-up.
Latitude tells you how far north or south of the equator a point is (from -90° to +90°), and longitude how far east or west of the Greenwich meridian (-180° to +180°). Together they pinpoint any place on Earth.
The same point can be written two ways. Decimal degrees pack it into two numbers — for example the Eiffel Tower is 48.85837, 2.29448. DMS splits each value into degrees, minutes and seconds — the same point reads 48°51'30.1"N 2°17'40.1"E. GPS receivers and phones usually show DD; nautical charts, aviation and older maps prefer DMS.
To convert, type an address to get its coordinates, paste decimal coordinates to read them back as an address and on the map, or enter DMS values to translate them to DD. Five decimal places give you roughly one-metre precision — enough for a doorstep — so you rarely need more than six.
Everything runs in your browser and nothing is stored. Use it to drop a pin for a delivery, read a coordinate off a hiking GPS, or check a figure before pasting it into a spreadsheet.
Frequently asked questions
How do I convert an address into GPS coordinates?
Type the address into the address field. We geocode it and show the latitude and longitude in decimal degrees, plus the matching point on the map.
What's the difference between DD and DMS?
Decimal degrees (DD) write a coordinate as two numbers like 48.8584, 2.2945. DMS splits each into degrees, minutes and seconds, like 48°51'30"N. They describe the same place — DD is easier to copy, DMS is common on charts.
How many decimal places do I need?
Five decimal places give about one metre of precision and six give about 10 cm. For most uses — an address, a meeting point — five is plenty.
Is the converter free, and is my data sent anywhere?
It's completely free with no account. The conversion math runs in your browser; only address look-ups call a geocoding service to resolve a place name.
