Hi all...I wonder...anybody point me in the direction to a conversion table/site for converting an O/S grid ref to Lat/Long.

Yes. Try this.

Thanks Terry...looks a bit involved...I suppose thinking about it...all I need is a way to convert an O/S Grid Ref to Lat/Long...I can then find that position on Google Earth,

So I should have asked how do I convert an O/S ref to lat/long...I will edit my heading to suit.

Nick.

Thanks, goldfrog, for that very useful link.

'Further or in the alternative', here's another one which might be handy, depending on Nick's actual activity:

Streetmap - Maps and directions for the whole of Great Britain (http://www.streetmap.co.uk)

- search for your location of interest (by whatever option) and, when the map appears, click on the link just below it (where it says "Click here to convert coordinates").

- you will be presented with a table displaying six- and ten-figure grid references, both traditional and decimal latitude & longitude (and other stuff) ..... quite brilliant, really.

Incidentally, I find their displays of high-res Ordnance Survey map sections on couple of their scale settings very useful indeed.

( ... so I must tip my hat to those helpful folks at Streetmap).

The OS site will also convert between coordinate systems (OS-Net | Ordnance Survey (http://www.ordnancesurvey.co.uk/gps/transformation)) and there is a downloadable spreadsheet linked on the same page.

If you actually want to see aerial photography with OS coordinates, this site will do it for you:
