What is a nautical mile (international)?

It is a length unit defined exactly as 1,852 meters, historically based on one minute of latitude on Earth, used mainly for marine and aeronautical distance measurements.

What does one chain represent?

One chain is a traditional surveying length of 66 feet or 20.1168 meters, commonly used historically for land measurements.

Why convert nautical miles to chains?

Converting these units aids tasks such as land parcel mapping, interpreting historical surveys, and integrating nautical measurements into land surveying records.
