تحويل الديكار إلى ميل مربع: قياس الأراضي وتقييم الممتلكات

One square mile equals approximately 258.9988 decares. This means a property measured as 1 square mile contains just under 259 decares. For practical purposes, professionals often use the approximation that 1 square mile ≈ 259 decares for quick mental calculations, though legal documents require the precise factor of 258.9988 decares per square mile for absolute accuracy in property transactions and boundary determinations.

The decare reflects the metric system's adoption across Europe, Turkey, and most of the world starting in the 1790s, providing a standardized, decimal-based measurement system. Square miles developed from English common law traditions and remained entrenched in Anglo-American legal systems, particularly in the United States, Canada, and historically British territories. This division reflects broader geopolitical and historical patterns—European nations standardized on metric measurements during the 19th and 20th centuries, while English-speaking nations maintained imperial measurements for legal continuity and practical consistency with existing property records spanning centuries.

A square mile is significantly larger than a decare. One square mile equals approximately 259 decares, making the square mile roughly 259 times larger. To visualize: if you divided a single square mile into equal portions, you could create approximately 259 separate decare plots. This size difference reflects their different historical purposes—decares measure individual agricultural plots and smaller properties, while square miles measure large jurisdictional areas, regions, and extensive land holdings.
