Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format. Geographical location information is represented in terms of **Latitude and Longitude**, where **Latitude** gives the angular distance of a point from equator to elevation either north or south, and **Longitude** gives the angular distance of a point east or west of the meridian. This Angular distance values of Lat and Lon is either represented in **Degree, Minute, Seconds(dd,mm,ss)** number system or **Decimal Degree** number system. So let us discuss about, how to represent the location with Latitude and Longitude, their value range and how to convert them with the tool.

#### Latitude** values Range:**

Point on **Equator line is calculated as 0° latitude,** while North pole as** 90°N** and South pole as** 90°S**. Latitude values range in between 0° and 90° in positive

(representing north) and in negative (representing south) values.

#### Longitude values Range:

Prime Meridian or Greenwich **meridian is defined as 0° longitude**. Longitude values ranges from **0° to 180°** east or from 0° to 180° west.

### Latitude and Longitude Representation – Different converted formats:

Generally in three formats, latitude and longitude values are represented. Let us take example of each format, by taking latitude longitude of San Antonio.

**1.) Degree Minutes Seconds :**

**For example:** 29° 25′ 26.5152″, -98° 29′ 37.6974″

**2.) Degree Decimal Minutes:**

**For example:** 29° 25.441916666667’ , -98° 29.6283’

**3.) Decimal Degree:**

**For example:** 29.424032, -98.493805

## Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format

Earth equator line is divided in 360 equal parts, each part represents a degree distance, where** ****1°=111.32 Km**. Every Degree is further divided in 60 minutes. This means, **1 minute = 111.32/60 = 1.85 Km,** and every minute is divided in 60 seconds. So **1 seconds = 1.85/60 = 0.0309 Km.**

### Convert Degree Minute Seconds to Degree Decimal for the Latitude Longitude values:

As 1°=60’=3600”, so we can compute degree decimal by:

**d = degree + minute / 60 + seconds/3600**

Let us take an **example**: Compute 29° 25′ 26.5152″, -98° 29′ 37.6974″ to degree decimal:

Latitude to Degree Decimal = d = 29 + 25/60 + 26.5152/3600 = 29.42432

Longitude to Degree Decimal = d = -(98 + 29/60 + 37.6974/3600) = -98.493805

#### Tool to convert lat lon values from degree minute seconds to degree decimal:

LATITUDE :Degree= Minute= Seconds=

LONGITUDE :Degree= Minute= Seconds=

### Convert Degree Minute Seconds to Degree Decimal:

Again, as **1°=60’=3600”**, we would compute Degree, Minute and Seconds separately from Degree Decimal.

**Degree**= integer part of Decimal degree = int(ddd.dd) = ddd.**Minute**= integer part of ((Decimal degree – Degree computed above) * 60) = int(ddd.dd – ddd) * 60.**Seconds**= (Degree Decimal – degree – Minute/60) * 3600 = (ddd.dd – ddd – m/60)*3600

Let us take an **example**. Compute 29.424032, -98.493805 to Degree Minute Seconds format:

**Degree** = int(29.424032) = 29

**Minute** = int((29.424032 – 29) * 60) = int (25.44192) = 25

**Seconds** = (29.424032 – 29 – 25/60) * 3600 = 26.5152″

**So latitude = 29° 25′ 26.5152”**

Similarly computing longitude of -98.493805, we get the degree minute second to **-98° 29′ 37.6974.**

#### Tool to convert lat lon values from Degree Decimal to Degree Minute Seconds:

### Convert – Degree Minute Seconds to Degree Decimal Minutes:

Fetch the **Seconds number**, and **divide it by 60**, and then **add** the result with **minute**,

**For example:** Convert 29° 25′ 26.5152” to Degree Decimal Minute:

- Here Seconds = 26.5152,
- so dividing it by 60 i.e 26.5152/60 = 0.44.
- Now add this with Minute, we will get
**29° 25.44,**which is in Degree Decimal Minutes format. If you multiply again 0.44 by 60 you will get again Degree Minute seconds format.
