At some point in time, degrees, minutes and seconds that had been used to designate coordinates on a chart were changed into degrees and decimal minutes. In another step, the morphed into decimal degrees. Google maps uses decimal degrees. Charts use degrees, minutes and seconds, and some chart plotters and other mapping tools use degrees with decimal minutes. It drives me crazy to try to figure out one from the other.
I finally found a website that does the conversion very easily. Plug in one number and out come the other two versions.
