About Square Furlongs
A square furlong is an area unit equal to a square with sides of one furlong (220 yards or ~201.17 m), approximately 40,469 m² or exactly 10 acres. The furlong (from Old English 'furrow-long') was historically the standard ploughing distance, and 10 square furlongs equals one acre - a relationship that made traditional land surveying convenient. While square furlongs are rarely used in official modern measurements, they appear in historical land surveys, British horse racing contexts, and as a handy reference for visualising 10-acre blocks.
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.
