Units explained
Finger
A finger is an Imperial unit of length equal to 4.5 inches (114.3 mm). It is one of the historical English cloth-measure units.
The finger derives from English cloth-trade tradition, where it was used as a small measure for ribbons and small fabric pieces. Standardised at 4.5 inches through English customary practice.
Fingers are rare in modern use; they appear primarily in historical English textile records and bartending (where 'a finger of whisky' is an informal usage roughly 1 inch, not 4.5).
Medieval English cloth-trade origin; standardised at 4.5 inches; the value became exact via the 1959 International Yard and Pound Agreement.
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 finger to lea:
1 × 2.367424e-5 = 2.367424e-5 lea
Example 2 — Convert 100 finger to lea:
100 × 2.367424e-5 = 0.0023674242 lea
Real-world example — Imperial yard-to-mile scale
1,760 fingers 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 finger × 2.367424e-5 = 0.0416666667 lea
Real-world example — Metric distance scale-up
One thousand fingers 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 finger × 2.367424e-5 = 0.0236742424 lea
Real-world example — Imperial mile arithmetic
5,280 fingers 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 finger × 2.367424e-5 = 0.125 lea
