Square Kilometer

The square kilometer (km²) is a unit of area in the metric system, equal to the area of a square with sides that are each 1 kilometer long. One square kilometer is equivalent to 1,000,000 square meters or 100 hectares. It is commonly used to measure large areas, such as the size of cities, countries, and geographical regions.

Origin:

The square kilometer is derived from the kilometer, which is a unit of length in the metric system. The kilometer itself was introduced in the 18th century as part of the metric system, based on the meter, which was originally defined as one ten-millionth of the distance from the North Pole to the equator. The square kilometer, like other area units in the metric system, is based on the square of the unit of length. As the metric system became more widely adopted worldwide, the square kilometer became a standard unit for measuring large areas, particularly in geography, urban planning, and land management.

Square Yard

A square yard (yd²) is a unit of area in the imperial system and the U.S. customary system. It is defined as the area of a square with sides that are each 1 yard long. One square yard is equal to 9 square feet or 0.8361 square meters.

Origin:

The square yard is derived from the yard, a unit of length in the imperial system. The yard was originally based on the length of a human's stride or other reference lengths in ancient times, but it became standardized in the 14th century during the reign of King Edward II of England. The square yard, as a unit of area, developed as a way to measure spaces like floors, gardens, and plots of land in a more manageable form than smaller units. The square yard continues to be used today, particularly in real estate, landscaping, and construction, mainly in countries that use the imperial or U.S. customary systems.
