History of Square Mile

The concept of measuring area by using squares dates back to ancient times. The ancient Egyptians, Babylonians, Greeks, and Romans all used different units of area based on squares with different side lengths. For example, the ancient Egyptians used a unit called setat, which was equal to a square with sides of 100 cubits (about 52 meters). The ancient Greeks used a unit called plethron, which was equal to a square with sides of 100 feet (about 30 meters). The ancient Romans used a unit called iugerum, which was equal to a square with sides of 120 feet (about 35 meters).

The modern definition of the square mile was established in the late 18th century by the British Parliament as part of the imperial system. The imperial system was designed to create a uniform and consistent system of measurement based on traditional units that were widely used in Britain and its colonies. The original definition of the mile was derived from an ancient Roman unit called mille passus (thousand paces), which was equal to about 5000 feet or 1480 meters. The original definition of the square mile was then derived from this definition as the area of a square whose sides are one mile long.

The definition of the mile has been revised several times over the years to improve its accuracy and precision. The current definition of the mile was adopted in 1959 by an international agreement as “the length equal to 1609.344 meters exactly”. The current definition of the square mile is then derived from this definition as before.
