About Square Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
About Square Micrometers
A square micrometer (μm²), also called a square micron, equals one trillionth of a square meter - the area of a square with sides one millionth of a meter (10⁻¹² m²). This is the natural scale of biological cells: a human red blood cell has a surface area of about 135 μm², and a typical bacterium might occupy 2-10 μm². Square micrometers are the standard unit in cell biology, histology, microscopy, and semiconductor characterisation where individual features on wafers are measured.
