Bigha to Acre Conversions — Every Amount, Every State

52 worked conversions, each answered for all 13 states. No single national figure, because there isn't one.

Short answer

The bigha is not a standardised unit, which is why every page here gives a state-wise range rather than one number — from the 1,600 square-yard bigha of West Bengal to the far smaller one used in Himachal Pradesh. Pick your conversion, then confirm the local figure with your district land revenue office before acting on it.

One conversion, thirteen answers

"How many acres is 10 bigha" does not have an answer. It has thirteen. In Uttarakhand it comes to 1.563 acres; in Uttar Pradesh the same ten bigha is 6.25. That is a fourfold spread on one question, and on a land deal it is the difference between plots worth very different sums.

The reason is straightforward. The acre is an international unit, fixed worldwide at exactly 43,560 square feet. The bigha is not. It is a customary unit that predates the metric system, and each state fixed its own against the local measuring rod in use at the time. Colonial-era settlement records then wrote those local values down rather than harmonising them, and they have stayed put ever since.

So every conversion page here leads with the range and then gives the figure for each state. A converter that publishes a single national number has quietly picked one region's convention and is wrong everywhere else — which is why the answer you want is never just a number, it is a number with a state attached to it.

Why does one bigha-to-acre conversion have thirteen answers?

There is no single national bigha-to-acre figure for India. Ten bigha, for example, is 1.563 acres in Uttarakhand and 6.25 acres in Uttar Pradesh — a fourfold difference on one question. An acre is fixed worldwide at exactly 43,560 square feet, but the bigha is a customary unit that each state defined for itself long before the metric system arrived. That is why every amount here has its own page, and why each page gives the figure for all thirteen states rather than an average that would be wrong everywhere. Several states also run competing conventions internally — a pucca and a kaccha bigha — so naming the state does not always settle the question on its own. These are commonly-cited reference figures derived from each state's traditional definition, not legal standards: the area recorded by your district land revenue office governs any transaction.

How to use these conversion pages

Three steps, including the one people most often skip.

1
Pick the amount you actually have
Choose the quantity you are converting — 10 bigha, 5 acres, whatever it is. Each page is worked out for that exact amount, so there is no arithmetic left for you to do.
2
Read your own state's row
Every table lists all thirteen states. The row that matters is the one your land sits in; the rest are there so you can see how far the figure moves across a border.
3
Confirm at district level
Several states run more than one convention at once — pucca and kaccha bigha, or separate hill and plain measures. Before agreeing a price, confirm the figure with your district land revenue office.

Commonly-cited approximate figure — confirm the exact local value with your state or district land revenue department before any transaction.

Bigha against other units

Square feet, square metres, killa, katha, biswa and the rest — each answered per state, because the bigha side of the sum changes.

Bigha to acre, by quantity

The exact amount you searched for, worked out for all thirteen states rather than averaged into one misleading number.

Acre to bigha, by quantity

The same sum in reverse. An acre is fixed at 43,560 square feet everywhere, so here it is the answer that moves.

Bigha to acre: frequently asked questions

How many bigha are in one acre?

It depends on the state. One acre is about 1.6 bigha in Uttar Pradesh, Bihar, Rajasthan and Jharkhand, 2 in Punjab and Haryana, 2.5 in Gujarat, 3.025 in West Bengal and Assam, 3.63 in Madhya Pradesh and Chhattisgarh, 5 in Himachal Pradesh and 6.4 in Uttarakhand. Any answer that does not name a state is guessing.

Why does the answer change from state to state?

The bigha was never defined against a physical standard. It was defined against local measuring rods, which differed between revenue surveys, and colonial settlement records documented those local values instead of harmonising them. Ten bigha is 1.563 acres in Uttarakhand and 6.25 in Uttar Pradesh for exactly that reason.

Which figure should I use on a sale deed?

None of these. Use the area recorded in your own land records. Deeds and mutation entries are written from the khasra, khatauni or record of rights held by the district land revenue office, and that figure governs the transaction. The conversions here are for understanding a listing or checking a quoted price, not for paperwork.

What if my state uses both pucca and kaccha bigha?

Then the state alone does not settle it and you have to ask which one a seller means. In Rajasthan a pucca bigha is 27,225 square feet against a kaccha bigha of 17,424 — a 56% gap on the same word. Western Uttar Pradesh uses a bigha roughly a quarter the size of the eastern one. Every conversion page lists the competing conventions for each state.

Is the bigha the same in Bangladesh and Nepal?

Bangladesh is different in a useful way: it inherited a single Bengal revenue system, so a bigha is 14,400 square feet everywhere — the same as West Bengal. Its official records are kept in shotangsho (decimal) rather than bigha, which catches people out. Nepal uses a bigha in the Terai and ropani in the hills; this site does not cover Nepal yet.
