- Press Convert to see the point in all three formats.
How it works
Coordinates can be written three ways: Decimal Degrees (DD, e.g. −31.953456°), Degrees-Minutes-Seconds (DMS, e.g. 31° 57′ 12″ S) and Degrees-Decimal-Minutes (DDM, e.g. 31° 57.207′ S).
One degree is 60 minutes, and one minute is 60 seconds. South latitudes and West longitudes are negative in decimal degrees.
Worked example
Perth, WA. −31.95345565° = 31° 57′ 12.44″ S in DMS.
