International system of units (SI) standardises most scientific measurements, land area measurement has two commonly used units hectares and acres. So this requires a reliable converter for converting between these units, ensuring clear communication and precise calculations.

Hectares: Definition, History

The hectare (ha) is a unit of area measurement within the SI metric system. Hectare was first established in 1795 during the French Revolution. One hectare is equivalent to 10,000 square meters (m²). Hectare was introduced to simplify land measurement by relating it to the established meter unit in the metric system.

Acres: Definition and History

An acre is a unit of land measurement in the imperial system. One acre equals to 4,840 square yards (yd²). Acre’s origin dates back to the ancient Roman empire when it was defined as “actus quadratus". Later acre was standardized in England and subsequently adopted by several other countries including the United States.

The formula for converting is Acres = Hectares * 2.471. This formula multiplies the value in hectares by 2.471, which is the conversion value between these two units.
