I chart that Gps cords for locations that I can not enter into my Gps because of it's different from what my Gps uses. for example 30degrees 14minutes, 21.1 seconds but my Gps show the Second like 422. I thought I read some where on a Coast Guard webcite that you can actually take the 21.1 form and multiply it by 20 to get it in the 422 format. Is this correct or is there another way to convert this seconds form to something I can use?
 
If its a Garmin you can change the format and read either way. I beleive to convert that mathmatically, divide your minutes by 60, that should give you decimal reading...or somthing like that.
 
My old Magellan works like that too.
30d 14m 21s becomes 30 degrees 14.35 minutes if you divide the seconds by 60 to convert to decimal minutes.

P.S. I guess we're lucky, the first satellite computing program required dividing the seconds by sixty, adding that number to the right of the decimal place, dividing the minutes by sixty and adding that to the degrees, dividing the degrees by 360 and multiplying by 256 for something else which had to be converted to binary for the 1962 computer to read it. Two math professors and two amateur radio operators came up with four different answers. Now my $5 Radio Shack calculator will figure out the cube root of a five digit number in less than a second. Boy I feel old.
