The plain answer, set in aurora light, followed by every fraction, nautical adjustment, and square-mile calculation you're likely to need — with an interactive converter.
A mile is 5,280 feet. That number isn't rounded — it's the exact modern definition. The mile inherits its length from 8 furlongs of 660 feet each, a unit English farmers used to measure a plough's daily work.
Since 1959, one international foot has been defined as 0.3048 m exactly, which makes a mile 1,609.344 m to the millimetre. Every conversion on this page is derived from that one number.

The English statute mile of 1593 defined a mile as 8 furlongs. A furlong was 40 rods, and a rod was 16½ feet. Multiplying it out gives 8 × 40 × 16.5 = 5,280 feet. The oddly specific number is a compromise between the Roman mille passus (1,000 paces ≈ 4,860 ft) and the tidy 8‑furlong plough field.
The nautical mile is defined by geography, not farming. It equals one minute of latitude — 1/60 of a degree — or exactly 1,852 meters. That works out to about 6,076.12 feet, roughly 15% longer than a statute mile. Pilots and sailors use it because a chart's latitude scale is the distance scale.
"Five tomatoes." Say it aloud: Five‑to‑ mat‑oes → 5‑2‑8‑0. Or picture eight furlongs, each 660 feet — the number a horse racer knows by heart.
