Units explained
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.
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.

Worked examples
Example 1 — Convert 1 ft to mi:
1 × 0.0001893939 = 0.0001893939 mi
Example 2 — Convert 100 ft to mi:
100 × 0.0001893939 = 0.0189393939 mi
Real-world example — Quarter-mile equivalent
3,000 feet equals 0.568 mile. The conversion is the standard 'sanity check' for road designers verifying that highway exit-ramp spacing (in feet) matches up with milestone distances (in miles).
3000 ft × 0.0001893939 = 0.5681818182 mi
Real-world example — One mile to feet
5,280 feet equals exactly 1 mile — the foundational US imperial conversion. American hikers tracking elevation gain in feet (from topographic maps) but trail length in miles use this constant every step of every hike.
5280 ft × 0.0001893939 = 1 mi
Real-world example — Half-marathon distance in feet
10,000 feet equals 1.89 miles — useful for race directors and fitness apps that need to translate between accumulated step counts (in feet) and recognizable race distances (in miles).
10000 ft × 0.0001893939 = 1.8939393939 mi
