GPS Coordinate Converter
Convert latitude and longitude into DD, DDM, DMS, UTM, MGRS, ARINC 424, and FMS formats. Reverse UTM or MGRS, then calculate distance and bearing between two points.
Converter
Paste a GPS coordinate. Get every format.
Use decimal degrees, DMS, DDM, UTM, or MGRS. This GPS coordinate converter accepts common latitude and longitude entries, then returns decimal degrees, DMS, UTM, MGRS, ARINC 424, and FMS formats.
You can paste coordinates like these
Use N/S/E/W or negative numbers. Spacing does not need to be perfect.

Formats
One coordinate, multiple operational views
UTM and MGRS
Grid-based position formats used when a map reference needs to be transferred without decimal latitude and longitude.
ARINC 424 and FMS
Aviation-friendly whole-degree formats for pilots who need waypoint-style coordinate references.
Distance and Bearing
Point-to-point distance in nautical miles, nautical miles UK, statute miles, and kilometers, with initial and reverse bearing.
