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.
About Square Thou
A square thou (thou²), sometimes called a square mil, is the area of a square with sides of one thousandth of an inch (0.0254 mm), equal to approximately 6.452 × 10⁻¹⁰ m². This tiny imperial unit is indispensable in precision engineering, PCB (printed circuit board) design, and manufacturing, where conductor widths, dielectric coating thicknesses, and tight machining tolerances are specified in thou. Wire insulation, thin films, and precision-stamped metal components are commonly described using this unit.
