GPS Toolset Coordinate converter
Turn a latitude and longitude into degrees, minutes and seconds, UTM, or MGRS. Paste a coordinate, or type one in.
Your coordinate never leaves your device.

How to convert a coordinate
-
1
Paste or type
Paste a coordinate in any of the forms below, or pick a form and fill the boxes. A click on the map sets the point too.
-
2
Read the others
Decimal degrees, DMS, DDM, UTM, and MGRS update together. South and west are negative in the decimal line.

Decimal, DMS, and DDM
A lat long converter is only a change of notation. These three lines are one place:
- Decimal 36.2361322, -115.0820944
- DMS 36° 14' 10.08" N, 115° 04' 55.54" W
- DDM 36° 14.1679' N, 115° 04.9257' W
Decimal degrees put the whole angle in one number. Latitude comes first. South and west are negative, so a point in the western hemisphere has a minus on the longitude.
DMS is degrees, minutes, and seconds, with N, S, E, or W. DDM keeps whole degrees and puts the rest in decimal minutes. Charts and radios often print DDM. Sixty minutes make one degree, and sixty seconds make one minute.
UTM
UTM writes the same place as metres inside a zone six degrees wide. The example above is:
- UTM 11S 672349.27 4011844.98
11 is the zone. S is the latitude band, not south. Bands run from C to X and skip I and O. Band S sits in the northern hemisphere, from 32°N to 40°N. This place is about 36°N, so the band is S. The first long number is metres east. The second is metres north.
A few zones in Norway and Svalbard are wider than six degrees. This page follows those zones. UTM covers 80°S to 84°N.
MGRS
MGRS is the grid printed on many maps. It starts from the UTM zone and band, adds two letters for a 100 km square, then digits for the easting and northing. The same place at 1 metre is:
- MGRS 11S PA 72349 11844
Spaces do not change the value. A shorter string is coarser: this page treats it as the centre of that square, then shows the 1 metre square inside it. MGRS uses the same latitude limits as UTM.
Privacy
There is no account and no upload. The numbers are converted in this browser. Closing the tab drops them. Map pictures load so the point can be shown. The coordinate is not sent as a saved place.
Questions
Does this upload the coordinate?
No. The conversion runs in this browser. GPS Toolset does not receive the numbers. The map loads pictures so you can see the place.
What is the difference between decimal, DMS, and DDM?
Decimal degrees are one number for latitude and one for longitude. South and west are negative. DMS splits each angle into degrees, minutes, and seconds. DDM keeps the degrees and uses decimal minutes. All three can name the same place.
What does the letter in a UTM coordinate mean?
It is a latitude band, not a compass direction. Bands run from C to X, skipping I and O. Band S is in the northern hemisphere. The two long numbers are metres east, then metres north, inside a zone.
What is MGRS?
MGRS is a grid used on many maps. It is built from UTM: a zone, a latitude band, two letters for a 100 km square, then digits. This page writes the 1 metre square. A shorter string is the centre of a larger square.
Which datum does this use?
WGS84, the same datum GPS uses. Decimal degrees, DMS, UTM, and MGRS on this page are all on that ellipsoid.
Why is there no UTM or MGRS near the poles?
UTM and MGRS cover 80°S to 84°N. Closer to a pole, decimal degrees and DMS still work.
Can I click the map?
Yes. A click sets the coordinate. You can also paste one or type it in. Use the zoom buttons on the map. Scrolling the page does not zoom it.
