Guntha to Square Feet Calculator
A guntha is what a Karnataka revenue record uses for a fraction of an acre. A brochure, a layout drawing and a sale agreement use square feet. One guntha is 1,089 square feet, and the conversion runs both ways below.

One to forty guntha, worked out
Forty guntha is where the unit stops: at forty the extent is an acre and the record starts counting acres again. Every figure below is 1,089 multiplied out — rounding is applied only at the last step, and each column carries the number of places that unit is actually quoted to, which is why the square-foot column has none and the acre column has four.

How it is worked out
Three constants, and where each one comes from
The whole page is two multiplications and a division. They are printed here so you can check it on paper rather than trusting it, and so the one factor that is customary rather than defined is marked as such.
An acre is 43,560 square feet — 4,840 square yards, and nine square feet to the square yard. Forty guntha make an acre, so one guntha is 43,560 ÷ 40 = 1,089 square feet. The same figure comes out of a square 33 feet on each side, which is how the unit is usually described on the ground, and out of 121 square yards.
Square metres come from a definition rather than a custom. One international foot is 0.3048 metres exactly, so a square foot is 0.09290304 square metres exactly, and a guntha is 101.17 square metres. Nothing about that relation varies by state, office or year.
The guntha itself is a different kind of number. Forty to the acre is the relation in general use in Karnataka and Maharashtra revenue practice; the arithmetic that follows from it is exact, but the unit is not defined by any statute this site quotes. Where a document states an extent in guntha, that stated extent governs and this page’s conversion does not — the same position our plot-size tool takes, for the same reason.
Both spellings are in ordinary use. Guntha and gunta are the same unit, and a record, an advertisement and a conversation about one plot will often use both.
Two figures, one extent
A revenue record writes an extent as acres and guntha — two columns, not one decimal. Read as a decimal it becomes a different piece of land, and nothing on the page looks wrong while it happens.
- 2 acres 20 guntha
- 1,08,900 sq ft2.5 acres. What the record says.
- Read as 2.20 acres
- 95,832 sq ft13,068 square feet — 12 guntha — that were never there.
The cent is the same trap from the other side: a hundred cents to the acre against forty guntha, so one guntha is 2.5 cents. Convert a plot between all five units, and see what its frontage and depth decide, on the plot size and dimensions tool.
What this unit measures
A guntha is land. It is not carpet area.
Ground, measured by a revenue record
Guntha, cent and acre measure a piece of ground. They are what a survey extract, a conversion order and a layout approval speak in, and they describe the extent of the parcel — not what stands on it and not what may be built on it. A plot advertised in square feet and recorded in guntha is one plot with two sizes attached, and the conversion above is the arithmetic that makes them the same sentence.
What the extent does not settle is what fits inside it. Setbacks, coverage and the permissible floor area ratio are fixed by the planning authority with jurisdiction over the plot, and none of them is a constant this page could publish.
Every reference tool we publish, each with a plain statement of what it cannot tell you, is listed on the tools index.
Floors, measured by a statute
Carpet area is the net usable floor area of an apartment, and it is the one area figure a buyer is quoted that has a statutory definition — section 2(k) of the Real Estate (Regulation and Development) Act, 2016. Built-up and super built-up areas are not defined by that Act at all, which is why what a seller includes in them has to be asked rather than assumed.
None of the three is a land measure, and no conversion connects them to a guntha. If you are holding an apartment’s quoted area rather than a plot’s extent, this is the wrong page and the two below are the right ones.
Read the statute’s own wording in the glossary entry on carpet area, and convert a quoted area on the carpet to super built-up tool.
This page converts a number you supplied. It does not measure anything, does not verify an extent, and takes no view on what may be built on any parcel. Where a layout drawing, a sale deed and a revenue record state different extents for the same land, it is the documents that settle it — not arithmetic done in a browser.
Questions
Guntha, answered
One guntha is 1,089 square feet. It follows from forty guntha to the acre and an acre of 43,560 square feet: 43,560 ÷ 40 = 1,089. The same figure comes out of a square 33 feet on each side, which is how the unit is usually described on the ground. In other units it is 121 square yards, a fortieth of an acre, and 101.17 square metres.
Forty guntha to the acre is the relation in general use in Karnataka and Maharashtra revenue practice, and it is the one this page converts on. The arithmetic that follows from it is exact. The unit itself is customary — no statute quoted anywhere on this site defines it — so where a document states an extent in guntha, that stated extent governs and a conversion made in a browser does not. The spelling varies too: guntha and gunta are the same unit.
Two acres plus twenty guntha, which is 2.5 acres and 1,08,900 square feet. It is not the decimal 2.20 acres, and reading it that way is the commonest measurement error on this corridor — it loses 12 guntha, or 13,068 square feet, without anything on the page looking wrong. The acre and the guntha are separate columns in a revenue record for exactly this reason. The panel above splits any figure you enter back into that pair.
No. Guntha, cent and acre measure land. Carpet area measures the inside of an apartment and is defined by section 2(k) of the Real Estate (Regulation and Development) Act, 2016 — a statutory definition with specific edges, which our glossary quotes in full. Converting a plot extent tells you nothing about a built-up, super built-up or carpet figure, and the two should never be compared as though they were the same quantity.
No, and they are subdivisions of the same acre, which is what makes the confusion easy. There are a hundred cents to an acre and forty guntha, so one guntha is 2.5 cents. The cent is the everyday unit on the Tamil Nadu side of this corridor and in much of rural Karnataka; the guntha is what Karnataka revenue records use for a fraction of an acre.
No. The dimension on a layout drawing, the area in a sale deed and the extent in the revenue record can all differ, and where they do it is the documents that settle it rather than any arithmetic. This page multiplies a figure you supplied by a constant. If the figure is wrong the answer is wrong, and nothing here can tell you that it is.
No. Every number on this page is either a conversion constant or arithmetic on a value you typed. No project area, plot size, price or rate appears anywhere on it, and nothing here is a representation about any SUYUG project. Our own published plot sizes and the registrations behind them are on the project pages and on the RERA page.
Ask for the extent in writing
A conversion settles the arithmetic. What settles the land is the survey number, the extent in the record, and the approvals over it — all of them documents you can ask for by name. Walk the site, and ask for them there.
