100acre

100 acres is a unit of land area used in countries that employ the acre for measuring property. One acre is defined as 43,560 square feet or 4,046.856 square meters, so 100 acres equals 4,356,000 square feet or 404,685.6 square meters. In metric terms this is about 40.4686 hectares, and in square miles it is roughly 0.15625 sq mi.

The acre originated in medieval England as the area of land that could be tilled in a day by a pair of oxen. The modern statute acre, standardized in the 19th century, is exactly 43,560 square feet and is the conventional unit used in the United States and other jurisdictions that follow the imperial system. In many countries that have adopted metric measurements, land is described in hectares instead of acres; thus, 100 acres is commonly expressed as approximately 40.47 hectares.

Usage and context: In real estate, agriculture, forestry, and large-scale development, 100-acre parcels describe substantial tracts of land. The practical implications of owning or subdividing 100 acres depend on factors such as topography, zoning, access, and infrastructure, rather than the exact shape of the area. Because metric measurements are often preferred in official records outside regions using the acre, 100 acres is frequently converted to hectares or square kilometers for international documentation. The term remains a standard descriptor for sizable rural land holdings in areas where the acre is customary.
