Hi, I am new to geocaching only found two so fat from geocache.com but I'm really hooked on it now.

Does anyone know if it's possible to convert OS grid references e.g.. SK 237 859 to Longitude/latitude co-ordinates?

reason I need to do this is we at the Badger club are notifies of Badger sets & are given OS grid references I cannot enter these into my Garmin GPS so need to convert them to co-ordinates.

Cheers.
