Converting hddd.mm.mmm to hddd.ddddd

Hope this isn't too stupid but could someone tell me how to convert
"hddd,mm.mmm" to "hddd.ddddd"
Example: N39 01.151 x W76 .45.856
I'm new to all GPS.
Thanks

 

Can you do time?

One minute of time is 1/60 of one hour, and one second is 1/60 of one
minute.

2 hours 15 minutes is 2.25 hours since 15 minutes is 15/60 (0.25) hours.


Position is no different. Sixty minutes make up each degree.

 

Better yet, go into your GPS setup menu. Set the coordinate format to
hddd.ddddd". Enter the coordinates. Now go back into setup and change
the coordinates to the desired format.

By hand:
Take the mm.mmm value and divide by 60, then add back in the whole number of
degrees. Using your example and rounding to 5 decimal places:

Northings: 1.151/60 = 0.01918. Merge back in the 39 to give 39.01918
Eastings: 45.856/60 = 0.76427. Merge back in the 76 to give 76.76427

Software:
I imagine most applications will do this. Mine certainly will (free
download from http://homepages.tesco.net/~Keith.Sheppard/MapMan.htm). Just
click on the Tools menu and choose Convert Coordinates. Choose the same
datum for both "Input Datum" and "Convert To". In your instance it doesn't
matter too much what datum you choose as long as it's one which has
coordinates in degrees. If in doubt, choose WGS84.

If offered the choice, make sure you choose "Use latitude/longitude". Type
in your Eastings and Northings and the answer will magically appear (in
several formats) in the results box.

Hardware:
Your GPS has probably got a setting to change the display format to one
which more accurately suits your requirements.
