تحويل الديكار إلى البوصة المربعة: قياس الأراضي والهندسة الدقيقة

One decare equals exactly 1,000 square meters, which converts to 1,550,003.1 square inches. To remember this: 1 square meter = 1,550.0031 square inches, and 1 decare = 1,000 square meters. This precise conversion factor is critical for engineering specifications and property documentation. For quick mental estimation, use the approximation that 1 decare ≈ 1.55 million square inches.

Decares reflect the metric system adopted in Europe and former Ottoman territories, providing decimal-based simplicity for land calculations. Square inches developed from the English measurement tradition used in North America and the United Kingdom, where land is typically measured in acres and square feet instead. The conversion becomes necessary when international projects combine metric-system land specifications with imperial-system engineering documentation, requiring precise translation between these fundamentally different measurement philosophies.
