About Square Millimeters
A square millimeter (mm²) is a metric unit of area equal to a square with sides of one millimeter. It is commonly used in precision engineering, electronics, and measuring very small surfaces such as microchips or printed circuit boards. To visualise: a typical pinhead has an area of about 2-3 mm². This unit is essential in microscopy, medical imaging, and manufacturing where tiny, precise measurements are critical.
About Townships
A township (twp) is a large survey unit used in the US Public Land Survey System, defined as a square with sides of 6 statute miles, giving exactly 36 square miles or approximately 93,240,000 m². Each township is subdivided into 36 one-square-mile sections of 640 acres each. The Township and Range system is how most US land west of Ohio was divided and sold; township numbers and names still appear in legal land descriptions, county records, and geographic placenames across the American Midwest and West.
