could someone tell me if there is a way of converting os map grid references into latitude/ longitude. i am thinking of doing moel elio on may 17, but have no local knowlege of the area and would like to put the grid references provided into my garmin 305.
I use this one but still have to fiddle between the decimals and minutes & seconds.Quote:

.... But if you had mapping software you could just upload straight to the Garmin without needing to convert it?
Not that I was bored waiting for the F1 GP to start or anything....

I use Tracklogs Maps, but I guess they all do much the same thing. I think they're right but no responsibility is taken!
thanks everyone, i will have to try out your suggestions. thanks to dominion working out the conversions for me i can now check i am getting it right,i am not that good with the computer.
Can't you put checkpoints into the Garmin using OS grid references anyway?
I know I can with my Garmin, but I don't know the model number and I haven't got it to hand.
Not with the Forerunner (wrist watch) models.Quote:

There is also a free downloadable tool that does this.
