What is a Square Yard and a Square Kilometer?
The square yard (symbol: yd², sq yd) is an imperial and US customary unit of area. It represents the area of a square with sides that are each one yard (3 feet or 36 inches) long.
The square kilometer (symbol: km²) is a decimal multiple of the SI unit of area, the square meter. It represents the area of a square with sides that are each one kilometer long (1 km² = 1,000,000 m²).
Note: The Square Yard is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Square Kilometer belongs to the metric (SI) system.
History of the Square Yard and Square Kilometer
Derived from the yard, a unit of length with origins possibly related to the human stride or arm span, the square yard became a standard area measurement in the English (and later imperial and US customary) systems. It was traditionally used for measuring textiles and smaller land areas.
As a multiple of the square meter, the square kilometer came into use alongside the metric system for measuring large areas like land masses, cities, and countries. Its adoption followed the establishment of the kilometer as a standard unit of distance.
