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.
