Frequently Asked Questions
How many cents make one acre?
100 cents = 1 acre = 43,560 sq.ft. So 1 cent = 435.6 sq.ft. Cent is the most common unit for plot sales across Tamil Nadu.
How many square feet is one ground in Chennai?
1 ground = 2,400 sq.ft. It is the standard unit for city plots in Chennai, and UDS (undivided share) for flats is often quoted against grounds. About 18.15 grounds make one acre.
What is a kuzhi and why do conversions differ?
Kuzhi is a traditional Tamil unit still found in old pattas and village records. In most of northern Tamil Nadu 1 kuzhi = 144 sq.ft (a 12×12 ft square), while in the Thanjavur delta and parts of southern TN 1 kuzhi = 576 sq.ft (24×24 ft). Always confirm which standard your village record follows — this converter supports both.
What are ma, kaani and veli in land measurement?
These are traditional agricultural units: 1 ma ≈ 14,400 sq.ft (about a third of an acre), 1 kaani ≈ 57,600 sq.ft (about 1.32 acres, common in southern districts), and 1 veli ≈ 2,88,000 sq.ft (about 6.6 acres). Exact values can vary between districts and old records.
Which unit is used in patta and government records?
Modern patta extracts and FMB sketches use hectares and ares (metric). 1 hectare = 2.47 acres = 1,07,639 sq.ft; 1 are = 1,076.4 sq.ft. Older records may still carry kuzhi, ma or kaani figures.

Disclaimer: Modern unit conversions (cent, ground, acre, hectare) are exact. Traditional Tamil units (kuzhi, ma, kaani, veli) vary by region and historical record — values here follow the most widely used standards. Always verify against your patta, FMB sketch or village record before any transaction.
