History and Origin of Hectares and Acres

The hectare was introduced in France in 1795 as part of the metric system, defined simply as 100 ares (10,000 square meters) to keep land measurement consistent with the new decimal units of length. The acre originated in medieval England as the amount of land a yoke of oxen could plough in a single day, and was later standardized under English law before spreading across the British Empire and the United States.
