Understanding Land Units in Tamil Nadu Property Documents
Tamil Nadu uses a mix of local and metric units across its property records. If you have ever looked at a sale deed or patta document, you have likely seen measurements in Cents, Grounds, or Ankanam without any conversion guide nearby.
For smaller plots and agricultural land, Cent is the standard unit. One Cent is 435.56 square feet, and 100 Cents make one Acre. A plot described as 25 Cents is about 10,889 square feet in area.
In Chennai and major Tamil Nadu cities, residential plots are commonly listed in Grounds. One Ground is exactly 2,400 square feet. A plot of 1.5 Grounds means 3,600 square feet.
Ankanam appears mostly in older documents and in specific taluks near the Andhra Pradesh border. One Ankanam is 72 square feet. If your old property document mentions Ankanam, this converter handles that unit as well.
1 Cent equals 435.56 square feet. This is a standard conversion used across Tamil Nadu, Andhra Pradesh, and Kerala. Cent is the most widely used unit for measuring small plots and agricultural land in these states. To convert Cents to square feet, multiply the number of Cents by 435.56.
1 Ground equals exactly 2,400 square feet or 222.97 square meters. This unit is commonly used in Chennai, Coimbatore, and Madurai for residential plot measurements. A plot described as 2 Grounds is 4,800 square feet.
1 Acre equals exactly 100 Cents. Since 1 Acre is 43,560 square feet and 1 Cent is 435.56 square feet, dividing 43,560 by 435.56 gives exactly 100. This relationship makes Cent and Acre easy to work with for agricultural land measurements.
Ankanam is a local measurement unit equal to 72 square feet. It is mostly found in older property documents and in certain taluks of Tamil Nadu near the Andhra Pradesh border, including parts of Tiruvannamalai, Villupuram, and some coastal areas. It is rarely used in new documents but still appears in older sale deeds and partition records.
To convert square meters to Cents, divide the area in square meters by 40.47. For example, 500 square meters divided by 40.47 is approximately 12.36 Cents. You can also use the converter above to get instant results for any unit combination.
Government patta and chitta documents in Tamil Nadu typically record agricultural land in Hectares and Ares. However, the practical measurements used in sale deeds are usually in Acres and Cents for agricultural land, and Grounds or Square Feet for urban residential plots.
