Convert Square Yard to Hectare

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.

The hectare was introduced in the 18th century as part of the metric system and is derived from the meter, the base unit of length in the metric system. The word "hectare" comes from the Greek word "hekaton" meaning "hundred," combined with the metric unit "are" (which represents 100 square meters). The hectare was designed to provide a practical unit for measuring larger areas, such as farmland and forests, in a way that fits within the metric system. Today, the hectare is widely used across the world for land measurement, although it is not commonly used in the United States, where acres are preferred instead.
