About nautical miles
The nautical mile is distinct from the statute mile, designed specifically for navigation. It was originally defined as one minute of latitude along any meridian, making it directly compatible with map coordinates. This allowed sailors to measure distance using the stars and a sextant. In 1929, it was standardized to exactly 1,852 meters. It is the basis for the 'knot' (one nautical mile per hour). nautical miles are commonly used in Ship navigation, Aircraft flight planning, International law (territorial waters), and Polar exploration, Meteorological forecasts.
A nautical mile is about 15% longer than a standard land mile.
About miles
The mile has a storied past, originating from the Roman 'mille passus'—literally 'a thousand paces,' where a pace was two steps. The modern 'statute mile' of 5,280 feet was codified during the reign of Queen Elizabeth I in 1593 to align with agricultural surveys (furlongs). While most of the world has switched to kilometers, the mile remains the king of the road in the United States and United Kingdom. miles are commonly used in US and UK highway distances, Speed limits (mph), Frequent flyer programs, and Running (the 4-minute mile), Railway trackage.
Walking at a brisk pace, you can cover a mile in about 15-20 minutes.
