The different GPS applications on PDAs and Smartphones seem to love to use different coordinate systems. Naturally you'd expect some simple application to convert these different systems from one to another, but all I seemed to find are either horribly buggy online conversions or standalone-apps which were not cross-platform and cost an arm and a leg (you wouldn't believe it, they charge you about USD 150 for such a tiny tool!). So I decided to roll my own here. Please please let me know if you find any bug as I'm not willing to be in the league of the inaccurate & buggy online-converters which are out there...
To perform a conversion, select the ellipsoid of your coordinates and then enter your coordinates in the appropriate section below. Then click on Convert of the respective section to see your coordinate in all the other formats.
