About Nautical Mile (nmi)
A unit of length used in maritime and air navigation, equal to exactly 1,852 meters (about 1.151 statute miles). The nautical mile was defined to equal one minute of arc of latitude along any meridian, making it uniquely useful for chart plotting — one degree of latitude is 60 nautical miles anywhere on Earth. International shipping, commercial aviation, and maritime speed (measured in knots, or nautical miles per hour) all use nautical miles as their native unit because the math of navigation is dramatically simpler than with statute miles.
About Mile (mi)
An imperial unit of length equal to 5,280 feet (1,609.344 meters). The statute mile evolved from the Roman mille passus ("a thousand paces") and remains the primary distance unit for roads, running, and real estate in the United States and United Kingdom. Marathon distance is 26.219 miles; US speed limits are in miles per hour; American geography — state sizes, road trips, fuel economy — is almost always expressed in miles. Converting to kilometers is one of the most common length conversions on the internet.
