What measurement unit or grid is this? I like to change the system of
measurment on my GPS so I do not have to convert when entering a coord that is
not in my usual hdd.mm.mmm format but this one has me foxed. It's from the USGS
topo maps so I would have thought it would be easy for me to figure out..
Tenas Lake lake Mount Washington 47.504ºN 123.160ºW

to convert the dec. part of degrees to minutes, multiply the dec. part
by 60
60 times .504 =3D 30.24 not 30.203333 60 times .160 =3D 9.6
not 9.676666
