Units explained
Link
A link is an Imperial unit of length equal to 7.92 inches (201.168 mm) — exactly 1/100 of a surveyor's chain. It is the smallest unit in the chain-based survey measurement system.
The link was defined by Edmund Gunter in 1620 as part of his 22-yard surveying chain. He divided the chain into 100 links specifically to enable easy decimal arithmetic when computing parcel areas.
Links appear in historical US and UK land survey documents (especially pre-1900). Modern surveyors generally use feet or meters but legacy deed records and government land surveys still cite acreage in chains and links.
Defined by Edmund Gunter in 1620; standardised as 7.92 inches via the chain definition; 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.

Step-by-step: convert links to leagues
- Write down the value in links (lk).
- Multiply that value by the factor 4.166667e-5.
- The product is the equivalent value in leagues (lea).
- To reverse, multiply the league value by 24000.
Worked examples
Example 1 — Convert 1 lk to lea:
1 × 4.166667e-5 = 4.166667e-5 lea
Example 2 — Convert 100 lk to lea:
100 × 4.166667e-5 = 0.0041666667 lea
Real-world example — Imperial yard-to-mile scale
1,760 links 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 lk × 4.166667e-5 = 0.0733333333 lea
Real-world example — Metric distance scale-up
One thousand links 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 lk × 4.166667e-5 = 0.0416666667 lea
Real-world example — Imperial mile arithmetic
5,280 links 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 lk × 4.166667e-5 = 0.22 lea
