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.
League
A league is an Imperial unit of length equal to 3 miles (about 4.83 km). It is one of the oldest distance units in English usage, historically representing the distance a person could walk in one hour.
The English league derives from the ancient Roman leuga via medieval English customary practice. Standardised at 3 statute miles in English law.
Leagues appear in historical English literature ('seven-league boots'), maritime navigation (a nautical league is 3 nautical miles), and traditional distance descriptions. Modern usage is largely literary.
Medieval English customary origin; standardised at 3 miles; became exact via the 1959 International Yard and Pound Agreement.

Worked examples
Example 1 — Convert 1 ft to lea:
1 × 6.313131e-5 = 6.313131e-5 lea
Example 2 — Convert 100 ft to lea:
100 × 6.313131e-5 = 0.0063131313 lea
Real-world example — Imperial yard-to-mile scale
1,760 feet equals exactly one league. American athletes and surveyors use this conversion to translate distances quoted in the smaller imperial unit into recognizable fractions of the larger geographic one.
1760 ft × 6.313131e-5 = 0.1111111111 lea
Real-world example — Metric distance scale-up
One thousand feet equals one league — the running distance for a 1K race or the standard metric kilometre-scale step. The simple thousand-fold conversion is the most-used metric distance translation.
1000 ft × 6.313131e-5 = 0.0631313131 lea
Real-world example — Imperial mile arithmetic
5,280 feet equals exactly one league. American hikers tracking elevation gain in the smaller unit but trail length in the larger one use this constant every time they read a topographic map.
5280 ft × 6.313131e-5 = 0.3333333333 lea
