One location, several valid formats
Decimal degrees express latitude and longitude as signed decimal numbers, while DMS breaks each degree into minutes and seconds. Decimal minutes sits between them by keeping whole degrees and expressing only the minutes as a decimal.
Those are just different ways to write the same geographic angles. Converting between them changes the notation, not the underlying position.
Decimal degrees = degrees + minutes/60 + seconds/3,600
Converts a DMS latitude or longitude into decimal degrees.
