How to Read DMS Coordinates

DMS stands for Degrees, Minutes, Seconds. It is a traditional way of writing latitude and longitude using degrees (°), minutes ('), seconds (") and a direction such as N, S, E or W.

How Do You Read DMS Coordinates?

Read the degrees first, then minutes, then seconds, followed by the direction.

18° 31' 13.548" N
73° 51' 24.2784" E
Degrees → Minutes → Seconds → Direction The first line represents latitude and the second represents longitude.

What Do Degrees, Minutes and Seconds Mean?

Degrees (°) The main angular unit.
Minutes (') 60 minutes make 1 degree.
Seconds (") 60 seconds make 1 minute.
N / S / E / W Indicates the geographic direction.

Breaking Down a DMS Coordinate

Consider this latitude:

18° 31' 13.548" N
1

18° — Degrees

The coordinate begins at 18 whole degrees.

2

31' — Minutes

The location is another 31 arc-minutes beyond the 18th degree.

3

13.548" — Seconds

Seconds provide additional precision within the minute.

4

N — North

N means the latitude is north of the Equator.

What Do N, S, E and W Mean in DMS Coordinates?

N North of the Equator
S South of the Equator
E East of the Prime Meridian
W West of the Prime Meridian

Reading Latitude and Longitude in DMS

Latitude DMS

18° 31' 13.548" N

Latitude ends with N or S because it describes position relative to the Equator.

Longitude DMS

73° 51' 24.2784" E

Longitude ends with E or W because it describes position relative to the Prime Meridian.

DMS vs Decimal Degrees

DMS and Decimal Degrees can represent the same location.

How DMS Converts to Decimal Degrees

Decimal Degrees = Degrees + Minutes ÷ 60 + Seconds ÷ 3600
1

Start with the DMS latitude

18° 31' 13.548" N

2

Apply the formula

18 + (31 ÷ 60) + (13.548 ÷ 3600)

3

Decimal result

Approximately 18.520430

Common DMS Coordinate Mistakes

Using minutes above 59

DMS minutes must be between 0 and 59.

Using seconds of 60 or more

Seconds must be less than 60.

Using the wrong direction

Latitude uses N/S while longitude uses E/W.

Mixing decimal and DMS notation

Keep each coordinate in one consistent format.
