Longitude & Latitude

Hello, just joined this group. Been using Google Earth since
its first
version by Keyhole in December 2004 now... there is still a
couple of
things I don't quite get.

How do you precisely translate the longitude and latitude
numbers of,
say, 41.26489N, 87.59973W to a proper 41°53'25.23"N, 
87°36'53.30"W?

What is the former numbers anyway? I only noticed that they
are not the
same; therefore do not represent the same exact location
longitudal and
latitudal-wise.

cheers!

Ok, basically:
41.26489° N is in a decimal like format

41° 53' 25" N is in the dms format (degrees minutes
seconds)

To convert between the two of them, you just need to know
that 53'
(minutes) is equal to 53/60 ° (degrees) and 25"
(seconds) is equal to
25/60 ' (minutes).  So, to convert from dms to the decimal
one, you
need to solve the following equation:
x = d + (m + s/60)/60
Where x is the longitude in the decimal format
d is the degrees
m is the minutes
s is the seconds

To go backwards is pretty much that in reverse (I'm too
lazy to type it
out, let me know if you need me to)
