Units explained
Township
A township is a unit of area used in the US Public Land Survey System (PLSS), equal to 36 square miles (approximately 93.24 km²).
Defined by the Land Ordinance of 1785 as a 6-mile by 6-mile square, divided into 36 sections of 1 square mile each.
Townships are the largest standard unit in the PLSS and appear in US public land records, county boundaries, and historical land grants throughout the central and western US.
Defined by the US Land Ordinance of 1785.
Square Millimeter
A square millimeter is a metric unit of area equal to 10⁻⁶ m² (1 mm × 1 mm). It is widely used in engineering, electronics, and small-scale technical work.
Derived by squaring the millimeter, defined as 1/1000 of a meter. The milli- prefix comes from the Latin 'mille' (thousand).
Square millimeters express PCB trace cross-sections, the area of small mechanical features in CAD drawings, biological sample sizes, and material thicknesses.
Millimeter has been part of the metric system since 1795.
