Land area unit converter — cent, ground, guntha, acre, sq ft, sq m
Indian land is quoted in a different unit every 200 kilometres. Convert one measurement into every unit at once, with the exact factor applied shown next to each result.

A calculator answers one question. A DevPartner assessment carries planning capacity, programme, cost, revenue, deal structure and cash flow through one deterministic model and freezes a versioned decision report.
Nothing from this calculator maps into the assessment intake, so you will start from a blank site. No opportunity is created until you save one.
How this calculator works
square feet = value × factor(unit) target = square feet ÷ factor(target unit) 1 acre = 43,560 sq ft 1 hectare = 1,07,639.104 sq ft 1 cent = 435.6 sq ft (1/100 acre) 1 ground = 2,400 sq ft 1 guntha = 1,089 sq ft (1/40 acre) 1 sq yd = 9 sq ft 1 sq m = 10.763910 sq ft

Why the unit matters more than the number
A site quoted at 40 cents in Coimbatore, 7.26 grounds in Chennai and 16 gunthas in Pune is the same 17,424 square feet of land. The number changes completely; the asset does not. Most avoidable errors in early land negotiation come from comparing a per-cent rate against a per-square-foot rate without converting first.
This converter applies fixed, published factors. Cent and guntha are defined as exact fractions of the acre — 1/100 and 1/40 — so they never drift. Ground is a Chennai-region convention of 2,400 square feet. Square yard, quoted as gaj across north India, is exactly nine square feet.
Where local practice can still differ
Revenue records occasionally carry a survey area that does not match a physical measurement of the same parcel, because the record predates modern survey and has been subdivided informally. Ankanam, kuzhi, bigha and katha vary materially between districts and are deliberately excluded here rather than given a false single value.
Always reconcile three numbers before you price a site: the area in the title document, the area in the latest revenue record, and the area from a physical survey. Where they disagree, the smaller reliable figure is the one that will govern what you can build.
Worked example
A Chennai site is described as 3 grounds. One ground is 2,400 sq ft, so the extent is 7,200 sq ft, which is 668.9 sq m or 0.165 acre. Priced at ₹9,500 per sq ft the same parcel is ₹6.84 crore; quoted per ground it is ₹2.28 crore per ground. Neither number is more correct than the other, but only one of them can be compared against a rate card expressed per square foot.
Run the same extent through the converter before you compare two offers. Most apparent bargains between cities are unit differences, not price differences.
Mistakes this converter is meant to prevent
Treating a cent as a fixed fraction of an acre in every district: it is 1/100 acre by definition here, but local revenue practice sometimes records rounded conversions in older documents, and the document controls the transaction, not the arithmetic.
Mixing survey extent with the extent after road widening or OSR surrender. The converter changes units; it does not know what has been given up.
Carrying a rounded conversion forward through five more calculations. Convert once, keep the full precision, and round only at the point of presentation.
Limits of this tool
Ground, cent and guntha are customary units whose recorded local values can vary. The factors used here are the widely published ones, shown on the page so you can check them against your document. Where the sale deed, patta or 7/12 extract states a different figure, that document governs.
For any transaction, the extent that matters is the surveyed extent in the title documents, not a converted number from a listing.
Frequently asked questions
- How many square feet is one cent?
- One cent is 435.6 square feet, because a cent is defined as one hundredth of an acre and an acre is 43,560 square feet. One hundred cents therefore make exactly one acre.
- How many square feet is one ground?
- One ground is 2,400 square feet. It is used mainly in Chennai and northern Tamil Nadu. An acre contains 18.15 grounds.
- How many gunthas make an acre?
- Forty gunthas make one acre, so one guntha is 1,089 square feet. The unit appears in Maharashtra, Karnataka, Gujarat and Telangana revenue records.
- Why is bigha not included?
- Bigha has no single national value — it ranges from roughly 1,600 to over 27,000 square feet depending on the state and even the district. Publishing one factor would be more misleading than omitting the unit. Convert your bigha figure locally, then enter the resulting square feet here.
