About Square Inches
A square inch (in²) is an imperial unit of area equal to a square with sides of one inch (25.4 mm × 25.4 mm). It is commonly used in the United States for measuring small areas like fabric swatches, screen sizes, or printed materials. A standard business card is about 6 in², and a typical smartphone screen might be 15-20 in². This unit remains prevalent in American manufacturing, printing, and retail.
About Dunam
A dunam (also dönüm or donum) is a unit of land area equal to exactly 1,000 m², used across Turkey, Israel, Palestine, Jordan, Lebanon, Iraq, and former Ottoman Empire territories. One dunam equals one stremma and one decare. The modern metric dunam of 1,000 m² was standardised during the British Mandate period; older Ottoman dunams varied by region (approximately 919-1,600 m²). It remains the primary land measurement unit for agricultural and property records throughout the Middle East, with properties routinely listed in dunams in Israeli and Palestinian real estate.
