About Square Miles
A square mile (mi²) is an imperial unit of area equal to a square with sides of one mile (5,280 ft × 5,280 ft). It is used for measuring large land areas like counties, states, and countries in the United States. Los Angeles covers about 503 mi², Rhode Island (smallest US state) is roughly 1,214 mi², and Alaska is about 665,384 mi². This unit is standard in American geography, land surveying, and regional planning.
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.
