How to find coordinates with Google Maps.

1. Go to Google Maps:
   http://maps.google.com/
2. Find place.
3. Place cursor exactly on top of the place of interest. The coordinates will appear as in the following photo:
   
4. Write down the coordinates. On the above example, they are:
   -33.494272, -58.328530
   (latitude, longitude).
5. In this format, the coordinates are correct, and you will be able to use them in Google Maps. However, the Google search engine won't recognize them. It is therefore convenient to re-express -33.494272, -58.328530 as
   33.494272S 58.328530W
   (comma is optional). If latitude is negative, as on the above example, write S (for south). If positive, write N. Similarly, for longitude, write W if negative and E if positive. For example,
   33.494272, 58.328530
   would be rewritten as
   33.494272N 58.328530E.

To see how the coordinates could be used, go to Google and enter
33.494272S 58.328530W

Note: The above photo (33.494272S 58.328530W) shows the ranch where I grew up in Soriano, Uruguay.
