Cent, acre, ground, hectare and sq.ft – Tamil Nadu land units explained
A seller says "3 cents", the patta says "0.01.21 hectares", the layout brochure says "1,320 sq.ft" and the bank wants square metres. They can all be the same plot. Here is the conversion table we use every day, and a calculator.
Conversion table
| Unit | sq.ft | sq.m | Cents | Notes |
|---|---|---|---|---|
| 1 cent / சென்ட் | 435.6 | 40.47 | 1 | Standard village unit in TN; 100 cents = 1 acre |
| 1 acre / ஏக்கர் | 43,560 | 4,046.86 | 100 | Farm land is priced per acre |
| 1 ground / கிரவுண்ட் | 2,400 | 222.97 | 5.51 | Older urban unit, still heard in town |
| 1 hectare / ஹெக்டேர் | 107,639 | 10,000 | 247.1 | = 2.471 acres; patta / chitta use hectares |
| 1 are / ஏர் | 1,076.4 | 100 | 2.471 | 1/100 hectare; patta shows Ha.Are.sq.m (e.g. 0.40.47 = 1 acre) |
| 1 sq.m / ச.மீ | 10.764 | 1 | 0.0247 | Used in registration documents |
| 1 kuzhi / குழி | ≈ 144 | ≈ 13.4 | ≈ 0.33 | Traditional; varies by region – always confirm in sq.ft |

Reading extent on a patta
Patta and chitta print extent as Hectare.Are.Sq.m – for example 0.40.47 means 0 hectares, 40 ares, 47 sq.m = 4,047 sq.m ≈ 1 acre. Sale deeds usually repeat it in sq.ft or cents as well. If the deed says 5 cents but the patta reads 0.01.62 Ha (1,620 sq.m ≈ 4 cents), the difference must be resolved – by survey – before you agree the price.
