How to convert1 square kilometer (sq km) = 1195990.05 square yard (sq yd). Square Kilometer (sq km) is a unit of Area used in Metric system. Square Yard (sq yd) is a unit of Area used in Standard system. Square Kilometer: A Unit of AreaDefinition of the Square KilometerA square kilometer is a unit of area that measures the size of a surface. It is defined as the area of a square whose sides are one kilometer long. A square kilometer is equal to 1,000,000 square meters, 100 hectares, or 0.386102 square miles. It is also the base unit of area in the metric system. How to Convert Square Kilometer to Other UnitsTo convert a square kilometer to other units of area, we need to multiply or divide by a conversion factor. A conversion factor is a number that relates two units of measurement. For example, to convert a square kilometer to a square mile, we need to multiply by 0.386102, which is the conversion factor between these two units. Here are some common conversion factors for square kilometer and other units of area:
Where Square Kilometer is UsedThe square kilometer is widely used around the world as a standard unit of area measurement. It is used for various purposes, such as measuring the size of countries, regions, cities, lakes, islands, parks, forests, and more. Different countries may have different preferences or regulations for using the square kilometer or other units of area in different applications. Here are some examples:
History of Square KilometerThe 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 kilometer was established in 1795 by the French Academy of Sciences as part of the metric system. The metric system was designed to create a universal and rational system of measurement based on natural phenomena and decimal multiples. The original definition of the meter was one tenmillionth of the distance from the equator to the North Pole along a meridian. The original definition of the square kilometer was then derived from this definition as the area of a square whose sides are one thousand meters long. The definition of the meter has been revised several times over the years to improve its accuracy and precision. The current definition of the meter was adopted in 1983 by the General Conference on Weights and Measures as “the length of the path travelled by light in vacuum during a time interval of 1/299792458 second”. The current definition of the square kilometer is then derived from this definition as before.

Square Yard: A Unit of AreaDefinition of the Square YardA square yard is a unit of area that measures the size of a surface. It is defined as the area of a square whose sides are one yard long. A square yard is equal to 9 square feet, 1296 square inches, or 0.836127 square meters. It is also a common unit of area in the United States customary system and the imperial system. How to Convert Square Yard to Other UnitsTo convert a square yard to other units of area, we need to multiply or divide by a conversion factor. A conversion factor is a number that relates two units of measurement. For example, to convert a square yard to a square meter, we need to multiply by 0.836127, which is the conversion factor between these two units.

Where Square Yard is UsedThe square yard is widely used in the United States, the United Kingdom, and some other countries as a standard unit of area measurement. It is used for various purposes, such as measuring the size of carpets, fabrics, lawns, gardens, sports fields, and more.

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 yard 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 yard was derived from an iron rod that was kept in London as a standard measure. The original definition of the square yard was then derived from this definition as the area of a square whose sides are one yard long. The definition of the yard has been revised several times over the years to improve its accuracy and precision. The current definition of the yard was adopted in 1959 by an international agreement as “the length equal to 0.9144 meter exactly”. The current definition of the square yard is then derived from this definition as before.
