Decimal Degrees (DD)
Format: 40.7128, -74.0060
Best for: Google Maps, API integrations, and simple sharing.
Degrees Minutes Seconds (DMS)
Format: 40 42' 46.08" N, 74 0' 21.6" W
Best for: Traditional maps, nautical navigation, and official property deeds.
Frequently Asked Questions
How do I convert lat long to decimal degrees?
To convert manually: Divide the minutes by 60, and the seconds by 3600. Add those numbers to the degrees. (e.g., 40 30' 0" = 40 + 0.5 = 40.5). South and West coordinates become negative.
Why are my coordinates showing up in the ocean?
The most common mistake is forgetting the negative sign for West Longitude (e.g., North America) or South Latitude. If you swap Latitude and Longitude, your point will also end up in unexpected locations (often the ocean near Africa).

GPS Accuracy Alert
Your phone's GPS can be off by 30 meters. This can cause critical errors in your data.

Using the wrong coordinate system (e.g. WGS84 vs NAD83) creates a permanent 1-meter offset.
