  • In Canada, the square meter is more commonly used for measuring the area of carpets, fabrics, and lawns, but the square yard is also used for some purposes.
  • In Australia and New Zealand, the square meter is more commonly used for measuring the area of carpets, fabrics, and lawns, but the square yard is also used for some purposes.

History of Square Yard

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 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.

  • In China, the square kilometer is used for measuring the area of provinces and municipalities, but the mu and the hectare are also used for measuring agricultural land.

History of Square Kilometer

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 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 ten-millionth 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.
