History of the Hectare

The hectare derives from the 'are,' a metric area unit (100 m²) introduced during the French Revolutionary metric reforms of the 1790s. 'Hecto-' is simply the SI prefix for 100, so a hectare is 100 ares.

Although not itself an SI unit, the hectare is officially accepted for use alongside SI units by the BIPM because of its practical importance in land measurement, and it remains the standard land-area unit in most of the world.

Historical origin. Hectare was not the invention of a single named person; it developed through the process described above.
