Units explained
Mile
A mile (statute mile) is an Imperial and US customary unit of length equal to 5,280 feet or exactly 1,609.344 meters. It is the standard unit for road distances in the United States and the United Kingdom.
The mile derives from the Roman mille passus ("thousand paces" — about 1,480 meters). The English statute mile was fixed at 5,280 feet by the Weights and Measures Act of 1593, and exactly defined as 1,609.344 m by the 1959 International Yard and Pound Agreement.
Miles are used in the US and UK for road signs, speed limits (mph), athletic events (one-mile run), and geographic distances. Aviation also uses statute miles for some visibility measurements.
Roman origin (mille passus); English statute mile fixed at 5,280 feet in 1593; standardized to 1,609.344 m exactly by the 1959 International Yard and Pound Agreement.
Foot
A foot is an Imperial and US customary unit of length equal to 12 inches or exactly 0.3048 meters. It is the most commonly used unit of length in everyday measurement in the United States.
The foot's origin is literally the length of a human foot, used as a measurement standard since antiquity. The English foot was standardized at various points in history; the modern international foot (0.3048 m exactly) was fixed by the 1959 International Yard and Pound Agreement.
Feet are used in the US for body height, building dimensions, room sizes, road sign clearances, aviation altitude (feet above sea level), and most everyday distance estimation. The UK uses feet informally for height despite officially being metric.
Used since antiquity; standardized to 0.3048 m exactly by the International Yard and Pound Agreement of 1959. Aviation worldwide uses feet for altitude despite metric adoption elsewhere.

Worked examples
Example 1 — Convert 1 mi to ft:
1 × 5280 = 5280 ft
Example 2 — Convert 100 mi to ft:
100 × 5280 = 528000 ft
Real-world example — Marathon distance in feet
A 26.2-mile marathon equals 138,336 feet — useful for trail-design engineers who specify lap markers in feet but advertise total race distance in miles.
26.2 mi × 5280 = 138336 ft
Real-world example — One mile to feet
1 mile equals 5,280 feet. American real-estate listings quote acreage and lot depth in feet but cite distance to features (highway exit, town centre) in miles — converting mile to feet is the routine arithmetic of every property listing.
1 mi × 5280 = 5280 ft
Real-world example — 5K race distance
A 5K race equals 3.1 miles, or 16,368 feet. Fitness-tracker pedometers translating step counts into recognizable race distances convert mi to ft as part of every workout summary.
3.1 mi × 5280 = 16368 ft
