Convert a GPS coordinate pair between the three common notations.
Decimal degrees, decimal minutes and full DMS are three renderings of one angle. Aviation and marine navigation use decimal minutes, while mapping software uses decimal degrees. Six decimal places resolve to about eleven centimetres, so more precision than that is spurious for any consumer GPS receiver.
GPS Coordinate Format
All three notations describe the same angle, differing only in how the fraction is expressed
