Latitude and Longitude representations

As most of us know latitude and longitude help us notate a place uniquely on earth.

There are basically three ways in which one can represent Latitude and Longitude.

1. In Degrees

The way Google, Yahoo, and Facebook API’s Use.

Ex: +40.7486, -77.8786

2. Degree Minutes and Seconds.

Ex: 40` 44′ 55”N,

3. Degree Minutes.

Ex: 40`44′,

In the First  Degrees notation + indicates it as North (for Latitude) or East ( for Longitude).

and – indicates that it is either at South (for Latitude) or west (for Longitude)

Let’s take a quick look at conversion from Format 1 to Format 2 and vice-versa.

From Format 1 to Format 2

1.  Let’s convert this 40.7486 to Degree-Minutes- Seconds Format

40.7486 degree => 40 Degree +0.7486 Degree.

As we know that 1 Degree = 60 Minutes it becomes

=>  40 Degree+0.7486*60 Minutes

=> 40 Degree+ 44.916 Minutes                    (Resembles our Format 3)

As we also know that 1 Minute = 60 Seconds it becomes

=>  40 Degree+44 Minutes+0.916 *60 Seconds

=> 40 Degree+44 Minute+   54.96Sceonds

=>40`44’55”

From Format 2 to Format1

40`44’55”      => 40 Degree +44 Minutes+55 Seconds.

As we know that 1 Minute = 60 Seconds it becomes

=>  40 Degree+44 Minutes+55/60 Minutes

=> 40 Degree+ 44.916Minutes                    (Resembles our Format 3)

As we also know that 1 Minute = 60 Degree

=>  40 Degree+44.916/60   => 40 Degree+0.7486 Degree

=>40.7486
