Tamil Nadu Land Area Converter — Cent, Ground
Tamil Nadu splits its land-unit usage cleanly along rural/urban lines. Patta and Chitta land records (agricultural and converted rural land) measure in Cent, the same 1/100-acre unit used in Kerala. Urban real estate — especially in Chennai — instead prices and lists land in Ground, a unit that doesn't exist in most other Indian states.

Why Tamil Nadu's Units Differ
Ground is fixed at exactly 2,400 sq ft everywhere in Tamil Nadu — there's no state-to-state ambiguity the way there is with Bigha, because Ground is a Tamil Nadu-specific unit rather than one shared (and redefined) across multiple states. It maps roughly to a traditional 40 ft × 60 ft house plot, which is why Chennai real estate listings almost always quote plot size in Ground rather than square feet.
Unit-by-Unit Reference
Cent
1 Cent = 435.6 sq ft = 40.47 sq m = 1/100 acre.
The standard unit on Tamil Nadu Patta and Chitta documents for agricultural and semi-urban land, identical in value to Kerala's Cent.
Ground
1 Ground = 2,400 sq ft = 223.03 sq m.
The default unit for urban residential land across Tamil Nadu, especially Chennai. Roughly equivalent to a 40 ft × 60 ft plot. 1 Ground = 5.5 Cent (approximately).
