Square Millimeter (mm²) to Square Inch (in²) Conversion

The square millimeter (mm²) is used for precision measurements in engineering and manufacturing. It's ideal for measuring tiny surfaces like electronic components (a microSD card is about 150 mm²) or paper thickness (standard printer paper is ~62,370 mm² per sheet). This unit is essential in microelectronics and quality control. The square inch (in²) is commonly used in the United States for small surface measurements. A standard post-it note is about 6 in², while a sheet of letter-sized paper is 93.5 in². This unit is prevalent in printing, crafts, and engineering drawings.
