How many square feet is one guntha, and how many guntha make an acre

One guntha is 1,089 square feet. One acre is equal to 40 guntha, and 1 acre is 43,560 square feet.

The second figure produces the first. 43,560 divided by 40 is 1,089, with nothing left over. From that same division, 1 guntha is 0.025 acre exactly, 121 square yards, and 101.17 square metres.

Guntha is written gunta in Karnataka revenue records and in most local conversation, and the two spellings mean the same unit. It is one of several units a seller may quote you. The same parcel can arrive described in acre, cent, gajam or square feet, depending on the district and on who is doing the describing.

What is the full conversion table for Karnataka land units

This table converts between the units used in Karnataka land dealings: square feet, square metre, square yard (gajam), guntha, cent, ankanam, acre and hectare.

One unit
Is equal to1 guntha | 1,089 sq ft; 121 sq yd (gajam); 101.17 sq m; 2.5 cent; 15.125 ankanam; 0.025 acre
1 acre | 43,560 sq ft; 4,840 gajam; 4,046.86 sq m; 40 guntha; 100 cent; 605 ankanam; 0.404686 hectare
1 cent | 435.6 sq ft; 48.4 gajam; 40.47 sq m; 0.4 guntha; 0.01 acre
1 gajam | 1 square yard; 9 sq ft; 0.836 sq m
1 ankanam | 72 sq ft; 8 gajam; 6.69 sq m
1 hectare | 10,000 sq m; 107,639 sq ft; 2.4711 acre; 98.84 guntha; 247.1 cent
1 square metre | 10.7639 sq ft

How this conversion table was built: every figure is computed from 1 acre = 43,560 square feet and the Karnataka ratios of 40 guntha and 100 cent to the acre. None of it is copied from another site. 

One further unit, anna, appears in some Karnataka listings at one sixteenth of a guntha. It is held out of the table on purpose.

Which unit a seller reaches for usually depends on where in Karnataka the land sits.

Which land units are actually used where in Karnataka?
Karnataka does not use one land unit statewide: guntha and acre for agricultural land in the interior, cent along the coast, and square feet for urban property in Bengaluru.

Cent is used in Mangalore and Udupi. Guntha is used in interior Karnataka for agricultural land, with the acre for anything larger. In Bengaluru, urban plots are quoted in square feet, which is why a site is described as 30 by 40 rather than as a share of an acre.
Gajam is the square yard under a Telugu name. 
Kaveri 2.0 has largely standardised registration records in square metres. Sale deeds and mutation extracts from before 2015 can still carry the local unit, so one parcel can hold two different units across its own paperwork.
Usage varies by district, and no published list of districts is complete. What settles the size of your parcel is not the district habit, it is the extent written in the revenue records. Even inside one unit, though, the published figures do not agree with each other.

Why do published guntha figures disagree with each other
Four of the pages that rank for this conversion publish different values for it: 0.025 acre, 0.0247 acre and 0.03 acre, all for the same 1 guntha. The exact figure is 0.025 acre, because 40 guntha make one acre.
on the first page of results for guntha to acre:

  • MagicBricks: 1 guntha is 0.024999966 acre, and 1 acre is 40.00005365 guntha.
  • Housing.com: 1 guntha is 0.024999 acre, and 1 acre is 40.0 guntha.
  • Bajaj Finserv: 1 guntha is 0.0247 acre, and 1 acre is approximately 40.47 guntha.
  • Tata Capital: 1 guntha is 0.03 acre.
  • indialandconverter.in: 1 guntha is 0.03 acre in Bangalore.

The first two are 0.025 carrying a rounding artefact, and both keep the 40-guntha rule. The other three do not. A guntha of 0.0247 acre implies 40.47 guntha to the acre, which contradicts the 40 that the same pages state elsewhere, and 0.03 is not 0.025 rounded either.

MagicBricks also records a Maharashtra variant on its square-feet-to-guntha page, read the same day: a guntha treated informally as 100 square metres, or 1,076.4 square feet. That runs about 1.2 percent smaller than the 1,089 square feet a Karnataka guntha carries.

A rounding difference moves the number by a fraction of a percent. A change of unit moves it much further.

How is a unit switch used to make a parcel sound bigger

A unit switch changes the figure without changing the land: 0.1492 acre, 5.97 guntha, 14.92 cent and 6,500 square feet all describe the same parcel. Converting every quoted figure into one unit before you compare is the only way to see which parcel is actually larger.

6,500 sounds bigger than 0.15. It is the same land, measured with a smaller ruler.

Where the gap opens up:

  • A plot advertised as 5 guntha should measure 5,445 square feet, which is 5 times 1,089. Buyers in Bengaluru peripheral areas have received 4,800 square feet against that expectation, because the seller worked from a local approximation of guntha rather than the revenue definition. (onecityproperty.com, common land measurement disputes)
  • The Maharashtra guntha of 1,076.4 square feet runs about 1.2 percent smaller than the Karnataka 1,089, for every guntha in the deal. (MagicBricks.)
  • A property in the Mangalore to Bengaluru transition zone can be described in cent in the sale deed and in guntha in the revenue records, so the two documents that should agree are not using the same unit. (onecityproperty.com.)
  • A layout deduction does the same work without any unit change: a plot sold as 1,200 square feet measuring 1,100 to 1,150 square feet once internal roads and common areas are accounted for. (onecityproperty.com.)

None of this needs bad intent. It needs two people using different units and nobody checking. The seller’s number is a claim. The revenue records and a licensed surveyor’s measurement are what settle it.

What do you check a stated measurement against before you pay

The seller’s stated extent is a claim until it matches the record. Check it against three things: the RTC for the survey number, the certified 11E sketch if the parcel has been subdivided, and a licensed surveyor’s physical measurement.

  • The RTC, also called the Pahani, records the extent of the parcel against its survey number in the Karnataka revenue record. Pull it for the survey number and hissa written on the sale deed, from Bhoomi.
  • The 11E sketch is a certified survey partition map issued by Survey Settlement and Land Records, required when a parcel is subdivided. Certified is the operative word: a statewide crackdown on fabricated 11E subdivisions began in 2025.
  • A licensed surveyor works from the tippan and produces a report with the physical dimensions in square feet and square metres, GPS coordinates for each boundary point, and a statement of whether the physical measurement matches the revenue record. A measurement by anyone not licensed by the Survey and Settlement Department carries no legal standing.

Verify all three before money moves, not after. Size matters after the purchase as well: in Karnataka, how many guntha the parcel runs to now shapes what you are allowed to do with it.

Does the size in guntha change what you are legally allowed to do with the plot

The size of an agricultural parcel in guntha now determines whether a land-use conversion application is accepted at all, as reported and not yet confirmed against a primary source.

As reported by beegru.com, a February 2026 circular directs Deputy Commissioners to reject outright any land-use conversion application for agricultural land of 5 guntha or smaller, under Section 95 of the Karnataka Land Revenue Act 1964. 5 guntha is 5,445 square feet, and that piece of arithmetic is not in doubt. The same report states that existing titles on parcels below the threshold remain valid, and that it is the DC conversion route that closes rather than the ownership.

The practical check follows from the section above: read the survey extent on the RTC rather than the seller’s stated size, because the recorded extent is what a Deputy Commissioner’s office will apply.

Figures like 5 guntha and 5,445 square feet are easier to hold on to when they are run against real, named parcels.

What does a real plot size look like in every unit
A 6,500 square foot managed farm plot is 5.97 guntha, 14.92 cent, 0.1492 acre and 603.87 square metres. 

The sizes below are in square feet, as the fact sheet records them, with the same area repeated in the units a seller might use. Every row is one plot size said five ways, so a quoted figure can be checked against what the plot actually measures. 

Plot size  | Guntha  | Cent  | Acre  | Square metres

6,500 sq ft managed farm plot  | 5.97  | 14.92  | 0.1492  | 603.87 

3,500 sq ft villa plot  | 3.21  | 8.03  | 0.0803  | 325.16 

8,000 sq ft villa plot  | 7.35  | 18.37  | 0.1837  | 743.22 

30,000 sq ft legacy estate  | 27.55  | 68.87  | 0.6887  | 2,787.09 

The same 6,500 square foot plot is also 722 gajam.
Whole estates read differently again. Vibez Sirivana in Chikkaballapur is 25 acres, which is 1,000 guntha, or 10.12 hectares. Vibez Coffee Estate in Sakleshpur is 35 acres, or 1,400 guntha, or 14.16 hectares. Vibez Kaira, also in Sakleshpur, is 40 acres, or 1,600 guntha, or 16.19 hectares. Across everything it manages, Vibez Estates holds 1,100 acres as at, which is 44,000 guntha, or 445.15 hectares. Its estates sit in corridors including Sakleshpur in Hassan district, Chikkaballapur and Chikmagalur.
