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 Acres

An acre is a traditional unit of land area used primarily in the United States, United Kingdom, and countries with British heritage. One acre equals 43,560 ft² or about 4,047 m². Historically based on the area a yoke of oxen could plow in one day, it remains the standard for measuring agricultural land, residential plots, and rural properties. A football field (without end zones) is roughly 1.32 acres, and most suburban house lots range from 0.25 to 1 acre.
