About Square Centimeters
A square centimeter (cm²) is a metric unit of area equal to a square with sides of one centimeter (10 mm × 10 mm). It is widely used for measuring moderate-sized surfaces like postage stamps, credit cards, or smartphone screens. A standard credit card has an area of about 46 cm². This unit is common in everyday crafts, school science, and smaller construction projects where precision matters but square meters would be too large.
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.
