A nautical mile is a unit of length equal to exactly 1,852 meters, historically based on one minute of arc of latitude along any meridian. Developed for maritime navigation because of its convenient relationship to latitude. One nautical mile corresponds to one minute (1/60 degree) of latitude. Internationally standardized at 1,852 meters in 1929.

Common uses of nautical miles include: Maritime navigation and shipping routes; Aviation distance and airspeed (knots = nmi/hour); Territorial water boundaries (12 nmi from shore); Oceanic weather forecasting and reporting.

A mile is an imperial unit of length equal to 5,280 feet, 1,760 yards, or exactly 1,609.344 meters. Derived from the Roman 'mille passus' (a thousand paces), originally 5,000 Roman feet. The statute mile of 5,280 feet was established by English Parliament in 1593 and standardized internationally in 1959.

Common uses of miles include: Road distances and speed limits in the US, UK, and Myanmar; Vehicle odometer readings in imperial countries; Running and fitness tracking (mile splits); Property and real estate distance descriptions.
