Can't you just change the display setting on your GPS to display points in ddd.mm.ss?

Normally that will also change the way the waypoints are displayed.

Try this spreadsheet Weisyboy.

I wrote it so that there can be 2 or 3 digits for the degrees, always 3 digits for minutes integers and always 4 digits for minutes decimal fractions.

The formulae go down to row 250.

thanks wb it works well i have never use excel befor but sound good to me.
