Are (Historical Land Unit)

Introduction : The are is a metric land measurement equal to 100 square meters (a 10m × 10m square). While largely replaced by hectares in modern use, it remains part of historical land records in some European countries.

History & Origin : Introduced in 1795 as part of the original metric system, from the Latin 'area' meaning open space. Used extensively in 19th century European land surveys but gradually superseded by the hectare (100 ares) for practical purposes.

Current Use : Still appears in some older property deeds in France and Scandinavia. Occasionally used for small garden plots or vineyard parcels. The decare (10 ares) remains in limited use in some Balkan countries.

Acre (US Survey Variant)

Introduction : The US survey acre is slightly different from the international acre, measuring about 4046.87 square meters compared to the international 4046.86 square meters. This subtle difference matters in precise land surveys and historical property boundaries.

History & Origin : The US survey system maintained its own standard based on the 1893 Mendenhall Order definitions, while the international acre was redefined in 1959. This created a 0.0002% difference that remains important for accurate retracing of original US surveys.

Current Use : Critical for maintaining consistency in US survey records. Used when retracing original property boundaries. Important for resolving land disputes where exact original measurements must be preserved. 640 US survey acres = 1 US survey square mile.
