Units explained
Perch
A perch is an Imperial unit of length identical to the rod — 16.5 feet (about 5.03 m). The names 'rod', 'perch', and 'pole' all refer to the same surveying unit and differ only by regional preference.
Like the rod, the perch derives from medieval English land-surveying. The name 'perch' was particularly common in legal land descriptions in Ireland and parts of the UK.
Perches appear in legacy land descriptions in Ireland, the UK, and historical US documents. Modern usage is rare.
Medieval English surveying origin; identical to the rod since 1620; 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 perch to lea:
1 × 0.0010416667 = 0.0010416667 lea
Example 2 — Convert 100 perch to lea:
100 × 0.0010416667 = 0.1041666667 lea
Real-world example — Imperial yard-to-mile scale
1,760 perches 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 perch × 0.0010416667 = 1.8333333333 lea
Real-world example — Metric distance scale-up
One thousand perches 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 perch × 0.0010416667 = 1.0416666667 lea
Real-world example — Imperial mile arithmetic
5,280 perches 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 perch × 0.0010416667 = 5.5 lea
