Convert GPS coordinates between decimal degrees, degrees minutes seconds, and degrees decimal minutes. This coordinate converter is useful for hiking, backpacking, mapping, trail planning, navigation, geocaching, and GPS waypoint entry.
Decimal degrees:
Enter latitude and longitude as decimal values, such as 39.7392 and -104.9903.
Degrees minutes seconds:
Enter degrees, minutes, seconds, and hemisphere direction for latitude and longitude.
Degrees decimal minutes:
Use the degrees and minutes fields. Decimal minutes can be entered in the minutes box when DDM is selected.
A GPS coordinate converter helps switch between formats used by trail maps, GPS devices, mapping apps, guidebooks, geocaching tools, and emergency location sharing.
Always double-check coordinates before navigating, especially in remote areas where a small formatting mistake can point to a very different location.
The basic coordinate conversion formulas are:
Decimal Degrees = degrees + minutes ÷ 60 + seconds ÷ 3600
Decimal Minutes = minutes + seconds ÷ 60
GPS coordinates are latitude and longitude values that describe a location on Earth. Latitude measures north or south, and longitude measures east or west.
Decimal degrees format shows coordinates as decimal numbers, such as 39.739200, -104.990300. Positive latitude is north, negative latitude is south, positive longitude is east, and negative longitude is west.
DMS means degrees, minutes, and seconds. A coordinate may look like 39° 44' 21.12" N, 104° 59' 25.08" W.
DDM means degrees and decimal minutes. A coordinate may look like 39° 44.352' N, 104° 59.418' W.
