The gunta is the working unit of agricultural land across Karnataka and Maharashtra, where it is also spelled **guntha**. Unlike the bigha, it does not change size as you move around. Learn one number and every other conversion follows.

## The one number

**1 gunta = 1,089 square feet.**

Everything else is arithmetic from there, because 1,089 was chosen to divide an acre cleanly:

**40 guntas = 1 acre = 43,560 square feet.**

It is also exactly 121 square yards, which is why older documents move between guntas and square yards without awkward decimals.

## The full table

| From      | To            | Value  |
| --------- | ------------- | ------ |
| 1 gunta   | square feet   | 1,089  |
| 1 gunta   | square yards  | 121    |
| 1 gunta   | square metres | 101.17 |
| 1 gunta   | cents         | 2.5    |
| 1 gunta   | acres         | 0.025  |
| 1 gunta   | ares          | 1.0117 |
| 1 acre    | guntas        | 40     |
| 1 cent    | guntas        | 0.4    |
| 1 hectare | guntas        | 98.84  |

**Gunta to cent is the one worth memorising: 1 gunta = 2.5 cents.** A cent is one hundredth of an acre and a gunta is one fortieth, so the ratio is 100/40. Going the other way, 1 cent = 0.4 gunta.

## Common conversions people actually search

- **1 gunta = 1,089 sq ft**
- **5 guntas = 5,445 sq ft = 12.5 cents**
- **10 guntas = 10,890 sq ft = 25 cents = 0.25 acre**
- **12 guntas = 13,068 sq ft = 30 cents**
- **20 guntas = 21,780 sq ft = 50 cents = half an acre**
- **30 guntas = 32,670 sq ft = 75 cents**
- **0.04 acre = 1.6 guntas**
- **1 acre 5 guntas = 48,005 sq ft = 1.125 acres**

That last one is where most of the confusion lives.

## Acres and guntas written as one number

Karnataka and Maharashtra revenue records state extents as **acres and guntas in two separate columns**. When that gets flattened into a single figure for a listing or a message, the two columns collapse with a dot between them -- and the dot is not a decimal point.

So "1.05 acres" in a Karnataka listing may well mean **1 acre 5 guntas**, which is 1.125 acres, not 1.05.

The quick test: **the gunta part can never exceed 39**, because 40 guntas is a full acre. If you see .36, .22 or .08, the gunta reading is possible. If you see .75 or .90, it must be decimal.

This single ambiguity is worth [a guide of its own](/blog/what-2-36-acres-means-land-listing), because on a parcel of any size the gap is real money.

## Converting in your head

Three shortcuts that cover most situations:

**Guntas to cents:** multiply by 2.5. Twelve guntas is 30 cents.

**Guntas to acres:** divide by 40, or move the decimal and divide by 4. Thirty guntas is 0.75 acre.

**Guntas to square feet:** multiply by about 1,100 and subtract a little. Close enough to sanity-check a quoted figure on the spot, and the [land unit converter](/tools/land-unit-converter) gives the exact number.

## Where guntas sit against other south Indian units

| Unit    | Square feet | Guntas |
| ------- | ----------- | ------ |
| Cent    | 435.6       | 0.4    |
| Gunta   | 1,089       | 1      |
| Ground  | 2,400       | 2.2    |
| Ankanam | 72          | 0.066  |

Cents dominate Tamil Nadu and Kerala, grounds are urban Tamil Nadu, and ankanams are Andhra and Telangana house sites. Detail in [south India's land units decoded](/blog/south-india-land-units-explained).

## Before you rely on a gunta figure

The number is stable, but the document still governs. Confirm that the extent in acres and guntas on the [RTC or Pahani](/blog/how-to-read-rtc-pahani-record) matches the sale deed and the survey sketch, and that the parcel on the ground is the parcel on the paper -- the method is in [verifying a survey number](/blog/how-to-verify-survey-number-land).

A conversion error nobody notices at the time becomes a boundary dispute later.
