Sorted, 'cos it's W the longitude is minus. Not all the online converters bother to show this...
Well, it's a hell of a lot closer than it was Simon.
I have the coordinates from sticking a pin in Google Earth, so I suspect the conversion is going tit's-up somewhere. It's a mile or 2 NE of where it should be. I'll watch out for the minus being missed next time. Next time I get over there, I'll be in it. I'll get the survey added in a bit.
Cheers for the link too Lister, duly bookmarked.
