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 Roods
A rood (ro) is a traditional English unit of land area equal to one quarter of an acre, or 40 square rods, approximately 1,011.71 m². Originating in medieval England, the rood was used alongside the acre and the perch for describing land ownership. The name shares its root with 'rod,' the linear unit used to measure it. While largely obsolete in modern use, roods still appear in old English legal documents, historical land surveys, and certain rural property records in England and Wales.
