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 Roods

A rood (ro) is a traditional English unit of land area equal to one quarter of an acre, or 40 square rods, approximately 1,011.71 m². Originating in medieval England, the rood was used alongside the acre and the perch for describing land ownership. The name shares its root with 'rod,' the linear unit used to measure it. While largely obsolete in modern use, roods still appear in old English legal documents, historical land surveys, and certain rural property records in England and Wales.
