If you're using your GPS mainly in UK then the ideal system to use is the Ordnance Survey map references. It is by far the easiest if you're navigating using one of their maps. The standard reference usually consists of two letters, followed by six figures which will pinpoint your location to within 100 metres, though most GPS systems will take it to a 12-figure reference taking it down to an accuracy of just one metre.
This is much easier than having to dissect map squares into degrees minutes and seconds ... (unless you're a sailor perhaps..)
