About Square Rods
A square rod (sq rd), also called a perch or square pole, equals the area of a square with sides of one rod (5.0292 m or 16.5 ft), giving approximately 25.29 m². This traditional unit was central to land surveying before the adoption of the metric system and remains embedded in legal property descriptions in the United States. There are exactly 160 square rods in one acre, and 40 square rods in one rood. Old farmland deeds and archaic land records in the UK and US frequently reference perches and square rods.
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.
