Definition

A square inch (in²) is an imperial unit of area equal to the area of a square with sides of 1 inch. It equals approximately 6.4516 square centimeters.

History

The square inch evolved from the British imperial system. The inch itself was historically defined as the width of a man's thumb, and was standardized to exactly 25.4 mm in 1959 by international agreement.

Current use

Square inches are used in the United States and the United Kingdom for measuring the area of small objects, cross-sections, screen sizes, pressure specifications (PSI), and manufacturing tolerances.
