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 Decimeters
A square decimeter (dm²) is a metric area unit equal to 100 square centimeters (10 cm × 10 cm) or 0.01 square meters. It represents roughly the footprint of a large paperback book or a standard floor tile. While less common in everyday language than cm² or m², square decimeters appear in cooking (pan sizes), packaging design, and as a useful stepping stone in metric calculations - notably, exactly 1 liter of liquid forms a layer 1 dm² × 1 cm deep.
