What is a nautical mile (international)?

It is a unit of length defined exactly as 1,852 meters, historically representing one minute of arc of latitude on Earth, mainly used in marine navigation.

What is a fathom used for?

A fathom is traditionally used to measure water depth and lengths of ropes or cables in nautical contexts.

How do I convert nautical miles to fathoms?

Use the conversion rate where 1 nautical mile equals approximately 1012.69 fathoms to translate distances into traditional nautical units.
