The GPS Coordinates Converter translates the same spot on Earth between the five coordinate formats you meet in practice. Decimal Degrees (DD) writes a location as two plain numbers, like 52.2297, 21.0122 — the format most software and web maps use. Degrees Minutes Seconds (DMS) splits each degree into 60 minutes and each minute into 60 seconds, the traditional style printed on paper maps. Degrees Decimal Minutes (DMM) is the middle ground — whole degrees plus decimal minutes — common on marine and handheld GPS units. UTM divides the world into 60 zones and states positions in meters within each zone, which surveyors like because distances become simple subtraction. MGRS is the military version of UTM that packs a position into one compact grid reference.
These systems all exist because different jobs need different trade-offs: software wants plain numbers, navigators want minutes, and anyone measuring on the ground wants meters. The converter moves between all of them instantly.
How it works
Enter coordinates in any of the five formats, paste them from another tool, or click the map — the converter immediately shows the same location in every format, plus the local time zone. Copy whichever version the device or software you are working with expects.
How to use the GPS Coordinates Converter
- 1
Enter coordinates or click the map
Type or paste coordinates in DD, DMS, DMM, UTM, or MGRS format, search for a place by name, or click a spot on the map.
- 2
Convert
MapGO instantly translates the location into all five coordinate formats and looks up its time zone.
- 3
Copy the format you need
Read or copy the converted coordinates in the format your GPS device, mapping software, or dataset requires.
What people use it for
Surveying
Convert field coordinates to UTM so distances and areas can be worked out in meters instead of degrees.
Aviation and military
Translate positions into MGRS grid references or DMS values used in flight plans, charts, and operational reporting.
Hiking GPS devices
Match the coordinate format on a handheld unit — often DMM or DMS — with the decimal degrees used by web maps.
Data cleaning
Normalize spreadsheets that mix coordinate styles into one consistent format before mapping or analysis.
Frequently asked questions
- Why are there so many coordinate formats?
- Each format grew out of a different job. Degrees, minutes, and seconds come from centuries of navigation; decimal degrees suit computers; UTM and MGRS state positions in meters, which is what surveyors and soldiers need on the ground.
- Which format should I use?
- Use Decimal Degrees for software, spreadsheets, and web maps; DMS or DMM for navigation devices and charts; and UTM or MGRS when you need to measure distances in meters or share a compact grid reference.
- What is MGRS?
- The Military Grid Reference System — a version of UTM used by NATO forces. It encodes a location as one string, such as 34UDC 12345 67890, where more digits mean more precision.
- Does the converter also show the time zone?
- Yes. Alongside the converted coordinates, the tool reports the time zone of the location, which is handy for scheduling and for logging observations in local time.
