Converting Ordnance Survey Grid Ref's to Lat/Long's

[Martinburney]

Hi All

There is a difference of opinion, which is the best programs to use, when converting from Ordnance Survey Grid References to Latitude / Longitude References, without referring to the Ordnance Survey Maps.

I am using multimap, which I personally feel suits my need, but it has been pointed out, that it is not totally accurate.

There are other systems available.

Would anyone recommend any other system, that they use, or is the only true accuracy, the various Ordnance Survey Maps published.
