Ask what a bigha is and you will get a confident answer. Ask in two states and you will get two confident answers that differ by a factor of four.

A bigha in Uttarakhand is 6,804 square feet. A bigha in Uttar Pradesh is 27,225 square feet. Same word, same country, two neighbouring states, four times the land.

This is not a quirk. It is the single most expensive unit of measurement in India, because it is used in high-volume land markets by people who assume everyone means the same thing.

## What a bigha actually is

The bigha is a traditional unit with no standard definition in national law. It predates metric standardisation and, in most places, predates the acre's arrival in Indian revenue records. What it measured was practical rather than geometric: roughly the land one pair of oxen could plough in a day, or the area a given quantity of seed would sow.

Because soil, terrain and practice differ, so did the area. Every region settled on its own value and kept it.

When the British revenue system imposed the acre as the administrative unit, the bigha did not disappear. It survived in everyday speech, in family conversation and in local negotiation, while the acre took over the paperwork. That split is still exactly where the problem lives: **the deal is discussed in bighas and recorded in acres.**

## The values, state by state

| State                 | Square feet per bigha | Bighas per acre |
| --------------------- | --------------------- | --------------- |
| Uttarakhand           | 6,804                 | 6.4             |
| Punjab, Haryana       | 9,072                 | 4.8             |
| Madhya Pradesh        | 12,000                | 3.63            |
| West Bengal           | 14,400                | 3.025           |
| Assam                 | 14,400                | 3.025           |
| Rajasthan (kaccha)    | 17,424                | 2.5             |
| Gujarat               | 17,427                | 2.5             |
| Bihar                 | 27,220                | 1.6             |
| Rajasthan (pucca)     | 27,225                | 1.6             |
| Uttar Pradesh (pucca) | 27,225                | 1.6             |

Even this table simplifies. Several states have district-level variation, and a few have village-level variation.

## Pucca and kaccha: the trap inside the trap

Rajasthan and Uttar Pradesh use two bighas at once.

The **pucca bigha** is 27,225 square feet, or 3,025 square yards. The **kaccha bigha** is 17,424 square feet in Rajasthan, which works out to exactly 0.4 acre.

They are both called "bigha". Which one applies depends on the district and, frequently, on who is speaking. A seller quoting pucca and a buyer hearing kaccha are 56 percent apart on the area, which on any meaningful parcel is a very large sum.

If you are transacting anywhere in Rajasthan or UP, **the first question is not the price per bigha. It is which bigha.**

## Where buyers actually lose money

**Price per unit comparison.** You see two parcels, one at ₹8 lakh per bigha in Gujarat and one at ₹12 lakh per bigha in Bihar, and conclude the first is cheaper. Per acre, the Gujarat parcel is ₹20 lakh and the Bihar parcel is ₹19.2 lakh. The cheaper-looking one costs more.

**Cross-state comparison in general.** Any mental model of "what land costs per bigha" built in one state is actively misleading in another. Convert to acres or square feet before comparing anything.

**Inherited land across a family spread over states.** Relatives describing holdings in bighas from different states will not be describing comparable things, and partition arithmetic done in mixed bighas goes wrong quickly. See [mother deed and chain of title](/blog/mother-deed-chain-of-title-explained) for why extent errors in a partition matter years later.

**The deed-versus-conversation gap.** This is the one that ends in litigation. The negotiation happens in bighas; the sale deed records acres or hectares. If the conversion was done loosely, you have agreed one area and bought another, and the document wins.

## How to protect yourself

**Convert everything to square feet immediately.** It is the one unit that does not shift, and the arithmetic is unambiguous. The full set of conversions is in the [Indian land units cheat sheet](/blog/land-unit-conversion-india-cheat-sheet).

**Ask the seller to state the extent in acres or hectares.** If they cannot or will not, that is information in itself.

**Check what the record says.** The [revenue record](/blog/how-to-read-rtc-pahani-record) and the sale deed carry an official extent. Compare it against the bigha figure you were quoted. A gap you cannot explain is a reason to stop, not to proceed carefully.

**Get it measured.** Where the sums justify it, an official survey settles the question for good. The process is in [verifying a survey number](/blog/how-to-verify-survey-number-land), and the on-site checks in the [farmland site visit checklist](/blog/farmland-site-visit-checklist).

**Write the conversion into the agreement.** If the deal was struck at a price per bigha, record in the agreement to sell both the bigha figure and the square-foot or acre equivalent you both agreed. It costs nothing and removes the ambiguity entirely.

## A note on the other travelling units

The bigha is the worst offender but not the only one. A **katha** is 720 square feet in West Bengal, 1,361 in Bihar and 2,880 in Assam. A **biswa** is a twentieth of whichever bigha applies, so it inherits the same problem. Detail on these is in the [north India](/blog/north-india-land-units-explained) and [cheat sheet](/blog/land-unit-conversion-india-cheat-sheet) guides.
