Units explained
Square Furlong
A square furlong is an imperial unit of area equal to exactly 40,468.564 m², or 10 acres.
Derived by squaring the furlong (660 feet or 1/8 mile). The furlong itself comes from medieval English 'furrow long', the length of a plowed furrow.
Square furlongs are rarely used today. The unit appears occasionally in historical English farming records and in some horseracing contexts (though usually as length, not area).
Medieval English origin; standardized via the 1959 International Yard and Pound Agreement.
Square Link
A square link is an imperial unit of area equal to approximately 0.0405 m². It is part of the chain-link surveying system used historically for land measurement.
Derived by squaring the link (1/100 of a chain = 7.92 inches). The Gunter's chain was introduced by English mathematician Edmund Gunter in 1620 for land surveying.
Square links appear in historical land surveys and legacy property records, particularly in the US Public Land Survey System (PLSS). Modern surveys use feet or meters instead.
Gunter's chain introduced in 1620; standardized via the 1959 International Yard and Pound Agreement.

- The product is the equivalent value in square links (lk²).
- To reverse, multiply the square link value by 1e-6.
Worked examples
Example 1 — Convert 1 fur² to lk²:
1 × 1000000.0055351607 = 1000000.0055351607 lk²
Example 2 — Convert 100 fur² to lk²:
100 × 1000000.0055351607 = 1e+8 lk²
Real-world example — Geographic to architectural conversion
One square furlong equals 100,000 square links. The conversion bridges geographic-scale survey work and architectural-scale building plans on the same drawing.
1 fur² × 1000000.0055351607 = 1000000.0055351607 lk²
Real-world example — Geographic to architectural scale
One square furlong equals 100,000 square links. Map scales use this when an architectural site plan (in the smaller unit) must be related to road-network plans (in the larger unit) on the same drawing.
1 fur² × 1000000.0055351607 = 1000000.0055351607 lk²
