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?
