title: Finding distance between two points using latitude and longitude in Degree Minutes Seconds format
body: <p>I am working on a tool to find the distance between two points whose latitude and longitude are given. Its ok when the latitude and longitude is given in <strong>Signed Degree Format</strong>. But I couldn't find a way to calculate the distance when latitude and longitude is given in <strong>Degree Minutes Seconds Format</strong> (ex:  N 11° 14' 52').Can anybody suggest me a way to find the distance ?</p>
