Units explained
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.
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.

Worked examples
Example 1 — Convert 1 ha to lk²:
1 × 247105.3828349333 = 247105.3828349333 lk²
Example 2 — Convert 100 ha to lk²:
100 × 247105.3828349333 = 2.471054e+7 lk²
Real-world example — Geographic to architectural scale
One hectare 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 ha × 247105.3828349333 = 247105.3828349333 lk²
Real-world example — Geographic to architectural conversion
One hectare equals 100,000 square links. The conversion bridges geographic-scale survey work and architectural-scale building plans on the same drawing.
1 ha × 247105.3828349333 = 247105.3828349333 lk²
