Interesting facts:
- The concept of the nautical mile dates back to ancient times when navigators needed a consistent way to measure distances at sea. The Earth's circumference was divided into 360 degrees of longitude, and each degree was further divided into 60 minutes of arc. One minute of latitude along any meridian became the basis for the nautical mile.
- The speed of ships and aircraft is commonly measured in knots, which are nautical miles per hour. One knot is equal to one nautical mile per hour. For example, a speed of 10 knots means the vessel is traveling at 10 nautical miles per hour.
