Units explained
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.
Furlong
A furlong is an Imperial unit of length equal to 660 feet, or exactly one eighth of a mile (about 201.17 m). It is the longest unit in the traditional English farm-and-survey system.
The furlong derives from Old English furh (furrow) + lang (long) — originally the length of a furrow in a typical medieval English open field. Standardised at 660 feet (= 10 chains = 220 yards = 1/8 mile) in medieval times.
Furlongs are the standard distance unit in horse racing (e.g., 'The race is 8 furlongs'), historical English farming and surveying, and occasional poetic or rhetorical usage. Modern racing courses worldwide list distances in furlongs.
Medieval English farming origin; standardised at 660 feet; remains the official distance unit in flat-racing thoroughbred horse races worldwide.

Worked examples
Example 1 — Convert 1 lea to fur:
1 × 24 = 24 fur
Example 2 — Convert 100 lea to fur:
100 × 24 = 2400 fur
Real-world example — Endurance race distances
A 50-league cycling or running race converts to a recognizable distance in furlongs. Endurance athletes coming from a different measurement system use this conversion to compare training plans across regions.
50 lea × 24 = 1200 fur
Real-world example — Maritime exclusion zone
A 200-league exclusion zone (a common maritime boundary) converts to a different value in furlongs that's useful when describing the same zone in everyday land-distance units.
200 lea × 24 = 4800 fur
Real-world example — Coastal cruise distances
A 10-league coastal sailing route converts to a different value in furlongs — useful for cruise operators who switch between maritime, aviation, and road-distance units depending on the leg of the trip.
10 lea × 24 = 240 fur
