What this tool does not do / Limits
This converts the numbers you enter and rounds seconds to whole seconds. It does not verify that the coordinates point to a real place.
Frequently asked questions
Why are seconds rounded?
Whole seconds are the common display format. Rounding can shift a point by up to about 15 metres, so keep decimals for precise work.
What ranges are accepted?
Latitude from -90 to 90 and longitude from -180 to 180. Values outside those ranges are rejected.
