What is an Acre?

An acre is a unit of land area used primarily in the United States, United Kingdom, Canada, and other countries that historically used the imperial measurement system. The acre has a rich history dating back to medieval times when it was defined as the amount of land that could be plowed in one day by a yoke of oxen.

Today, the acre is precisely defined in terms of metric units:

Other equivalent definitions include:

• 43,560 square feet (exact definition in US survey)
• 4,840 square yards
• 0.404686 hectares
• 1/640 of a square mile

What is a Square Meter?

A square meter (symbol: m²) is the SI (International System of Units) derived unit of area. It is defined as the area of a square with sides measuring exactly one meter. The square meter is used worldwide as the standard unit for measuring land area in real estate, construction, and scientific applications.

Acres vs. Hectares

While acres are common in the United States and United Kingdom, hectares are the standard metric unit for land measurement used internationally. The relationship is:

• 1 hectare = 10,000 square meters
• 1 hectare ≈ 2.471 acres
• 1 acre ≈ 0.4047 hectares

History of the Acre

The word "acre" comes from the Old English word "æcer," meaning "open field." Historically, an acre was defined as the area of land that could be plowed in one day by one man with one ox. This practical definition varied by location and soil conditions.

In 1878, the British Weights and Measures Act standardized the acre at exactly 4,840 square yards. The international acre used today is based on the international yard (0.9144 meters exactly), making 1 acre = 4,046.8564224 square meters exactly.

Applications of Acre to Square Meter Conversion

Real Estate

Construction and Development

Land developers, architects, and urban planners frequently convert land areas when working on international projects or using software with different unit systems.

Environmental Studies

Scientists and conservationists use both measurement systems when documenting land use, deforestation, or habitat areas across different countries.
