## Coordinate Formats

There are three geographic coordinate formats -- decimal degrees (DD), degrees, minutes (DM) and degrees, minutes, seconds (DMS).

Coordinate Format Explanation Example
DM Format Degrees, Minutes N 50° 06.164′ E 014° 19.569′
DMS Format Degrees, Minutes, Seconds N 50° 06′ 9.86″ E 014° 19′ 34.14″
DD Format Decimal Degrees N 50.102740° E 014.326150°

All the example coordinates above point to the same place. Most GPS units use the DM Format.

### How to Convert Between Various Coordinate Formats?

The formula is very simple. You just need to know this:
1 degree = 60 minutes
1 minute = 60 seconds

Let's say we need to convert N 42° 22.150′ E 11° 45.295′ to decimal degrees. In this case, the calculation will look like this:
Latitude = N 42 + (22.150 / 60) = N 42.369167°
Longitude = E 11 + (45.295 / 60) = E 11.754917°.

We can the same coordinates write also in DMS format:
Latitude = N 42° 22′ + (0.150 * 60) = N 42° 22′ 9″
Longitude = E 11° 45′ + (0.295 * 60) = E 11° 45′ 17.70″
