Long/Lat 5 to 6 FIgure ??

[BADGER.BRAD]

Hello All,
Has anyone any idea how to convert a 5 figure reference to 6 ? Would 52.399N 03.681w just need a 0 adding on to the end of each figure ? or do I need to add it else where ? Grid ref for my GPS and The Hug mapping site don't match.

Thanks all

5 fig is standard lat/long co-ordinates, 6 fig is British National Grid (used on OS maps etc). You have to convert them using something like this

Thanks Andy, much appreciated. I had just presumed my GPS was set up in Long/Lat, I'll have to have a look in the settings to see if I can set it to long/lat to match the system my mapping software uses.

Cheers.

My Garmin Etrex certainly has such an option. I have it set to give OS grid references. I thought it would be useful if I ever had to call out the emergency services and I needed to tell them exactly where I was.

Just tried the convetor but It seems to come up with figures that make no sense at all ? the mapping software gives two figures os grid and what I presumed to be long lat at 5 figures my gps or phone takes nearly the same long lat but with one number missing off each. Hope that makes sense ?

You might find this website useful for converting or checking conversions.

Edit
Just noticed Andy R has already given you link to a converter website, never mind, use the one you prefer.

Grid references consist of two letters (L) and 10 digits (D) in the following format LL DDDDD DDDDD, but the digits in the corresponding Lat/Long are completely different ,there is no comparison.
You may have to convert the letters to digital form, this website should help you do that

There are four ways of defining the same position on the map
Example, OS grid ref NO 42821 11326, becomes 342821 711326, which is equivalent to 56.29018 -2.9253347 and equiv. to 56.29018N 2.9253347W

Actually there are more than four ways, but four is enough for just now!

Still making no sense a point on the map using the Hug online mapping gives me 52.555n -2.124w using snorri's grid ref finder I get 52.554545n -2.1243772w one appears as a shorter version of the other ( there may be a slight difference due to where I pointed the mouse) . Any way I'm off now for a couple of days Trekking in the Breacon Beacons I think I'll stick to following an OS map rather than a GPS . I've used the GPS in the past for routes on well diffined paths and a bit of Geocaching but until I can work out the difference between the two figures the maps the best bet. Any more help appreciated.

The accuracy/precision that you need will depend on what you're using it for.

For example 52.555N is expressed to the nearest 0.001 of a degree, which is about 120 yards, whereas 52.554545N is to the nearest 0.000001 of a degree i.e. about 4 inches.

Thanks User9609 much appreciated I wasn't sure if it was as easy as adding a figure on the end of lon/lat to get a 6 figure ref from a 5 figure ref. My device expects a 6 figure ref (I had it set for geocaching)
