What exactly is a nautical mile (international)?

It is a unit of length defined exactly as 1,852 meters, historically tied to one minute of arc of latitude on Earth, commonly used in marine and aeronautical navigation.

Why convert nautical miles to kilometers?

Converting to kilometers allows for easier interpretation and communication of maritime and aeronautical distances within the metric system used for land measurements.

Can I use this conversion for speed calculations in knots?

Yes, since one knot equals one nautical mile per hour, converting distances to kilometers supports combined use with speed measurements.
