What is Nautical Mile?

The nautical mile is a unit of distance used in maritime and air navigation, defined as exactly 1,852 meters. It was originally based on one minute of arc of latitude along any meridian of the Earth, making it naturally suited for navigation on charts. The knot, a unit of speed equal to one nautical mile per hour, is derived from this unit. Nautical miles are used internationally for charting sea and air routes, and they remain the standard in maritime law and international treaties governing territorial waters.

What is Mile?

The mile is a unit of length in the imperial and US customary systems, defined as exactly 1,609.344 meters. Its origin traces back to the Roman "mille passus," meaning one thousand paces. In the United States and the United Kingdom, road distances and speed limits are posted in miles, and car odometers display mileage. The mile is also central to airline frequent-flyer programs, where travel distances are tracked and rewarded in miles.
