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.
Ground (Chennai)
A ground is a unit of land area used primarily in Chennai (Tamil Nadu), equal to exactly 2400 square feet, or approximately 222.967 m².
Standardized at 2400 sq ft in the Madras (Chennai) area during the colonial era. The name 'ground' is a direct English translation used in local property documentation.
Grounds are the primary unit for residential property in Chennai and surrounding Tamil Nadu districts. Property advertisements in Chennai commonly use grounds alongside square feet (24 grounds = 1 acre).
Standardized in colonial Madras Presidency.
