Type or paste, latitude first – as decimal degrees, degrees and minutes, or degrees, minutes and seconds. Spaces are fine instead of ° ′ ″.
Which format for what?
Aboard, degrees and decimal minutes are the standard: charts, plotters and GPS show 54°19.398′ N, and that is how a position is passed over the radio. Degrees, minutes and seconds appear on land maps and in older documents, decimal degrees in map apps. One minute of latitude is one nautical mile, so 0.001′ is just under 2 m.
Also in the ClearShip app: Coordinate Converter
Works offline on board where there is no signal, next to the anchor alarm and your boat's maintenance tasks.
