Square Meter to Acre Converter

A square meter (m²) is the SI base unit of area, equal to the area of a square with sides of one meter each. It serves as the fundamental unit from which all other metric area measurements are derived.

The square meter was established alongside the meter during the French Revolution in 1795 as part of the metric system. As the meter became the base unit of length, its square naturally became the base unit of area. It was officially adopted as part of the International System of Units (SI) in 1960.

Square meters are universally used for measuring floor areas, room sizes, small properties, construction materials, and in scientific applications. They're standard in architecture, construction, real estate listings, and manufacturing. Most building codes and construction specifications use square meters.

An acre (ac) is a unit of area traditionally defined as the amount of land a yoke of oxen could plow in one day. It equals 43,560 square feet or approximately 4,047 square meters, making it ideal for measuring agricultural and residential land.

The acre originated in medieval England around the 13th century, derived from the Old English 'æcer' meaning 'field'. It was originally defined as a furlong (660 feet) long by one chain (66 feet) wide, representing a practical day's work for a farmer. The acre was standardized in various forms across different regions before being internationally defined.

Acres are extensively used in the United States, United Kingdom, Canada, and other Commonwealth countries for measuring farmland, residential properties, and real estate. They're standard in agricultural reports, property listings, land development, and zoning regulations in these countries.
