Units explained
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.
Arpent (French)
A French arpent is a historical unit of land area used in pre-metric France, approximately 4221 m² (close to one acre).
Originated as a medieval French land unit; varied considerably by province. The 'arpent de Paris' was officially fixed at 100 perches squared, the perche being 18 pieds.
French arpents appear in pre-revolutionary French land records and in genealogical research. The unit was largely abolished after the French Revolution in favor of metric units.
Medieval French origin; abolished after the French Revolution in favor of metric.
