Co-Ordinate Format Standard?

These are the options on my Garmin, as well as various National Grids.

h ddd mm ss.s
h ddd mm.mmm
h ddd.ddddd

Which one is the standard one?

Just looked on Mike Warners site showing Moto friendly places to stay in France and this the format he uses, I think it's degree decimal?

44.738534,1.275659

Is there something I'm missing here :confused:

44.738534,1.275659 is ddd.ddddd

that's basically degrees and decimal degrees

apologies if I'm teaching granny to suck eggs but

d = degrees
m = minutes (60 minutes in one degree)
s = seconds (60 seconds in one minute)

so

if you needed to convert your 44.738534 to ddd mm.mmm

you would take the degrees as 44
minutes = 60 * 0.738534 = 44.31204

ddd mm.mmm = 44° 44.312', 1° 16.539' (I skipped the calculation for the longitude)

you could then convert that to ddd mm ss.sss by
degrees = 44
minutes = 44
seconds = 60 * 0.31204 = 16.53954

so dd mm ss.sss = 44° 44' 16.540" N, 1° 16' 32.372" E

The easiest way to convert them though is to enter a waypoint into your GPS in whatever format you're given then switch the GPS back to your normal format.

or you could just click on this link ;-)

Ok, what is the GPS coordinates: N4319.209 W045.733 in the same format as this...... N41.58051 E0.62073?

Why can't everone agree on a standard and use it? :(

Not sure about that one! Where's it from?

Where in the Vale are you from? I was brought up in Granby!

It's this campsite here, I've found it on the map but I'd just like to know how to easily convert the odd co-ords that websites keep using.

Finding the place on Google maps

and then using http://www.gps2cad.com/CoordTrans/CoordConvert.aspx

to fart about with different values

Looks like Degrees. Decimal Minutes i.e. N43 19.209 W0 45.733 - then convert to "google" values

43.3202°
-0.7622°

http://maps.google.co.uk/?ie=UTF8&ll=43.3202,-0.7622&spn=0.003368,0.008261&t=h&z=18

looks close enough to me :)
 
The format I use looks like this, N43 27 33.4 W3 48 18.9 It's the default one Mapsource uses when it’s first installed (I think).

The coordinate convert I use is this one http://boulter.com/gps/ seems happy to munch different formats and its another feature completely missing in Mapsource. Google maps though is pretty good.
