Bigha to Acre, Hectare & Square Yard Conversion Guide

Why Bigha Has No Single National Value

India has run on the metric system as its sole legal standard of measurement since 1957, so official land records — the ceiling calculations in every state's agricultural land law, the area fields in a modern digitised revenue record — ultimately express area in hectares or square metres. The Bigha predates all of that. It was never a unit defined once by a central authority and then handed down uniformly; it was a village-level, practical unit that each local revenue survey fixed independently, using whatever rope, chain, or pole length that particular settlement operation adopted.

That single fact explains almost everything a buyer needs to know before trusting a quoted Bigha figure. A Bigha in Rajasthan's Pucca (पक्का) system is roughly 0.625 acre. A Bigha in Himachal Pradesh is roughly 0.2 acre — nearly a third the size. A Bigha in western Uttar Pradesh can be smaller again, while a Bigha in Lucknow or the state's eastern districts swells back up to roughly the Rajasthan figure. None of these are "wrong" — each is simply the figure that particular region's settlement history fixed, and each remains the operative figure in that region's revenue records to this day.

For a buyer working across this corridor — comparing a Rajasthan farmhouse plot against a Haryana parcel against a Himachal hillside — the practical rule is simple to state and easy to forget under time pressure: a Bigha figure is only meaningful once you know which state's, and sometimes which district's, Bigha it refers to. Everything in this guide exists to make that confirmation quick rather than guesswork.

Square Yard, Gaj and the Standard Reference Units

Before working through the Bigha's variations, it's worth fixing the units this entire guide ultimately converts back to — the units that appear on official documents, government portals, and any converter tool worth trusting.

• Square Yard / Gaj (गज) — the everyday unit for residential and farmhouse-sized plots across North India, and the unit most corridor conversions ultimately reduce to for a practical, human-scale comparison. 1 Square Yard = 9 square feet ≈ 0.836 square metres. "Gaj" and "square yard" are used interchangeably in this corridor's listings and revenue documents.
• Square Feet — the finest-grained standard unit, and the easiest one to state a precise Bigha conversion factor in, since a Bigha's square-yard or acre figure is often itself a rounded version of a cleaner square-foot number.
• Acre — the traditional English unit still in wide informal and semi-official use. 1 Acre = 43,560 square feet = 4,840 square yards ≈ 0.4047 hectares.
• Hectare — the standard metric unit, and the unit every ceiling act and most modern digitised land records in this corridor ultimately express area in. 1 Hectare = 10,000 square metres ≈ 2.471 acres.

The reason this guide converts every Bigha figure into all four of these columns, rather than just one, is that different documents in a single transaction will use different reference units — a broker's verbal quote in Bigha, a sale deed drafted in square yards, and a ceiling-law calculation expressed in hectares. Being able to move fluidly between all four, starting from whichever local Bigha figure actually applies, is the practical skill this guide is built to give you.

Where the Bigha Comes From: A Brief History

The Bigha's variability isn't an accident of poor record-keeping — it's a direct inheritance from how land was actually measured for centuries before any modern survey authority existed. Under Akbar's 16th-century administrative reforms, a standard measure — the ilahi gaz — was fixed, and a Bigha of that era was defined as 3,600 square ilahi-guz, a figure later reckoned as roughly equivalent to 3,025 square yards of the modern yard. That single Mughal-era standardisation is the ancestor of the "Pucca Bigha ≈ 3,025 square yards" figure still quoted in Rajasthan and in central and eastern Uttar Pradesh today.

What happened next is the part that actually produced today's patchwork. Village-level revenue measurement in the centuries that followed was carried out by a local patwari using a rope or chain — known locally as a lattha or jarib — whose length was itself a local convention, not a centrally issued standard. A British settlement commissioner reviewing North Indian land records in the 1920s is on record describing roughly forty different Bigha measures then in active use across the region, built on chains ranging from about 100 feet to 185 feet in length — and noting that some of that variation was itself the product of landlords quietly shortening the measuring chain to inflate the apparent rent yield per unit of land. Once a village's fields had been surveyed and recorded under one particular chain length, that figure became the operative local Bigha for that village's revenue record — and, in the many places where no fresh settlement has re-measured the land since, it still is.

Three things followed from this history, and all three are still true today. First, a Bigha's size was calibrated to local land-survey convention, not to any property of the land itself — there's no agricultural logic that makes a western Uttar Pradesh field naturally different in "Bigha-ness" from an eastern one. Second, once fixed in a village's revenue record, that figure has enormous inertia — a full re-survey happens only once every several decades in most districts, so an 1880s chain length can still be the operative figure in a 2026 khasra extract. Third, and most importantly for a buyer, this history is exactly why no single national conversion factor exists to look up — the number was always a local fact, not a universal constant, and it remains one.

It's worth being clear about how much of this history is well-documented versus how much is reasonable inference. The Mughal-era ilahi-gaz standardisation and the existence of British-era settlement variation are both well-attested in general historical and reference sources. The specific chain length or Bigha figure that was fixed for any one particular village a century or more ago, however, is not something this guide can verify — it lives in that village's own settlement records, if they still exist, not in any secondary source we could confirm for this article. Treat the history here as the honest explanation for why the variation exists, not as a way to derive today's figure for a specific parcel without checking the current local record.

Kaccha Bigha vs Pucca Bigha

Across much of this corridor, and most explicitly in Rajasthan, the Bigha doesn't even come as a single figure within one state — it comes in two, distinguished as Pucca (roughly "standard" or "full") and Kachha (कच्चा, roughly "raw" or "informal"). Both terms are still in genuine, simultaneous use in local speech and in revenue documents, and a buyer who doesn't ask which one applies is guessing at a factor-of-1.5 difference in the actual land area.

• Pucca Bigha — the larger, more "complete" measure. In Rajasthan this works out to 27,225 square feet (3,025 square yards), approximately 2,529 square metres, roughly 0.625 acre — tracing back to the Mughal-era ilahi-gaz standard described above.
• Kachha Bigha — the smaller, customary measure. In Rajasthan this is 17,424 square feet (1,936 square yards), approximately 1,619 square metres, roughly 0.4 acre.

The Pucca/Kachha distinction isn't unique to Rajasthan — it echoes through the corridor under different labels. Uttarakhand's plains districts use a Bigha that follows this same Kachha-style figure (roughly 17,424 square feet), distinct from the smaller hill-district Bigha covered in the state snapshot below. Some Haryana and Punjab sources describe a "Pukhta" Bigha figure that tracks closer to the Pucca number, though — as flagged in the state snapshot — this belt's Bigha usage is genuinely inconsistent enough that we recommend leaning on the Kanal-Marla system there instead of any Bigha figure.

State-by-State Bigha Snapshot

Here is the short version of what each corridor state's Bigha actually means, cross-checked across multiple independent sources for this guide. Full worked figures are in the master table below.

Rajasthan

Runs the Pucca/Kachha system described above, side by side, with the specific district and document determining which one applies to a given parcel. Both figures genuinely coexist in local usage and in revenue records across Rajasthan's districts — this isn't a case of one being the "correct" modern figure and the other an outdated one, and a buyer moving between, say, Jaipur-belt and Marwar-belt districts should expect to confirm the applicable variant fresh in each location rather than carrying an assumption forward from the last district they researched. See our dedicated Rajasthan Bigha and Biswa guide for the full district-by-district picture.

Haryana and Punjab

The Bigha is used far less consistently here than anywhere else in the corridor, precisely because the Kanal-Marla system is this belt's dominant everyday and revenue-record unit. Our own research for this guide found genuine disagreement between sources on a Haryana/Punjab Bigha figure — one common citation places it around 8,712 square feet (close to the Himachal figure below), while other sources describe a larger "Pukhta" Bigha closer to the Rajasthan Pucca figure. We were not able to resolve this to one confident number, and we recommend treating Kanal-Marla, not Bigha, as the reliable reference unit for any Haryana or Punjab parcel.

Uttar Pradesh

The most variable Bigha in the entire corridor — variable enough that it gets its own full deep-dive article, linked in full below. In short: a western UP Bigha and a central or eastern UP Bigha can differ by roughly four times for the identical unit name.

Uttarakhand

Runs two different Bigha figures depending on whether you're in a hill district or a plains district. The hill-district Bigha (roughly 6,806 square feet) matches the smaller western-UP-style figure, cross-checking arithmetically against the state's own Nali unit (a hill Bigha works out to approximately 3.15 Nali). The plains-district Bigha follows the larger, Kachha-style figure instead.

Himachal Pradesh

A smaller, hill-calibrated Bigha at approximately 8,712 square feet (968 square yards) — with the convenient shorthand that 5 Bigha equal almost exactly 1 acre in HP's system (5 × 8,712 = 43,560 square feet, precisely one acre).

Uttar Pradesh: One State, Several Bighas

Uttar Pradesh deserves a separate note here because its internal variation is large enough to change how you should even approach a UP land search. Western UP districts commonly use a Bigha of roughly 6,806 square feet — about 756 square yards — while a second, slightly larger western figure of roughly 9,075 square feet also appears in some local usage. Central and eastern UP districts, including Lucknow, commonly use a Bigha of roughly 27,225 square feet — the same figure as Rajasthan's Pucca Bigha — a difference of close to four times within the borders of a single state.

This guide deliberately does not attempt to give you a single "UP Bigha" figure, because doing so would itself be the mistake this entire article exists to prevent. Our companion deep-dive, Bigha in Uttar Pradesh — District-wise Variations, covers the district-level picture, the historical settlement reasons behind it, and exactly which figures we could and couldn't independently confirm. If you're evaluating any UP parcel specifically, treat that article — not the general table below — as your primary reference.

Master Conversion Table: Bigha to Square Yard, Square Feet, Acre and Hectare

The table below converts every figure introduced above into a consistent set of reference columns for Farmland India's six corridor states. Treat every row as a starting reference to confirm locally, not a number to plug directly into a contract — the notes column flags exactly where that confirmation matters most.

Worked Conversion Examples

Example 1: The four-times trap. Suppose a broker in a western UP district quotes you "4 Bigha" using the roughly 6,806-square-foot local figure. Four of those Bigha equal 27,225 square feet — which happens to be exactly one Rajasthan Pucca Bigha. If you mentally price that western UP quote using the Rajasthan Pucca conversion instead of the correct local one, you'll believe you're buying a parcel four times larger than the western UP figure actually delivers. On a real transaction, that's the difference between a 0.625-acre parcel and a 0.156-acre one — for the identical phrase, "4 Bigha," spoken by two different sellers in two different districts.

Example 2: Converting for a ceiling-law check. Say you're assembling a 15-Bigha holding in Rajasthan, quoted in the Pucca system, and you need to check it against a ceiling limit expressed in hectares (every ceiling act in this corridor states its limits in hectares or acres, never in Bigha). 15 Bigha × 27,225 square feet = 408,375 square feet. Converting: 408,375 ÷ 43,560 = 9.375 acres, and 9.375 × 0.4047 ≈ 3.79 hectares. That final hectare figure — not the "15 Bigha" figure — is the one that actually matters against a written ceiling limit, and it's only correct if the Pucca assumption was correct in the first place.

Example 3: A clean cross-check. Himachal Pradesh's own shorthand — 5 Bigha to the acre — is a useful sanity check for any HP figure you're given: 5 × 8,712 square feet = 43,560 square feet, precisely one acre. If a Himachal quote doesn't land close to that ratio when you do the arithmetic, that's worth a direct question before you proceed, not an assumption that the math is fine.

Example 4: Comparing a per-Bigha price across two states. Say a Rajasthan seller quotes ₹18 lakh per Pucca Bigha, and a Himachal Pradesh seller quotes ₹8 lakh per Bigha for a comparable hillside plot. Converted to a common reference unit: ₹18 lakh ÷ 0.625 acre ≈ ₹28.8 lakh per acre for the Rajasthan parcel, while ₹8 lakh ÷ 0.2 acre = ₹40 lakh per acre for the Himachal parcel. Read as raw per-Bigha prices, the Himachal quote looks cheaper; converted to a common per-acre basis, it's actually the more expensive parcel per unit of land. This is exactly the comparison a buyer needs before deciding between two states, and it's impossible to make correctly without converting both quotes to the same reference unit first.

Common Mistakes Comparing Land Ads Across States

Most of the buyer mistakes this guide exists to prevent aren't arithmetic errors — they're the result of skipping a confirmation step under the time pressure of a live negotiation. The pattern repeats often enough across this corridor's listings and broker conversations that it's worth naming each version explicitly:

• Applying one state's Bigha figure to another state's listing. The single most common and most expensive mistake in this guide — a "per Bigha" price from Rajasthan and a "per Bigha" price from Himachal Pradesh are not comparable numbers until both are converted to the same reference unit, because the underlying Bigha itself differs by roughly three times between them. This mistake is especially easy to make when browsing listings across multiple states in one sitting, where the eye naturally anchors on whichever Bigha figure it saw most recently.
• Skipping the Pucca-versus-Kachha question. Wherever this distinction applies, not asking it outright means guessing at a 56% area difference — large enough to change whether a parcel meets a minimum-size requirement you had in mind.
• Trusting an online calculator's default state. Many generic converter tools quote a single national "1 Bigha = X" figure with no state selector at all, or bury the state selector below a default that's easy to miss — a red flag, given everything covered in this guide, and a reason to double-check which state a tool's output actually assumes before trusting it.
• Ignoring the Biswa count printed in the ad itself. A listing that specifies "5 Biswa" versus "20 Biswa" per Bigha is telling you directly which regional Bigha applies — that detail is a clue, not clutter, and it's worth reading rather than skipping past on the way to the price line.
• Rounding early in a large-parcel calculation. A small per-Bigha rounding error, multiplied across a 20-Bigha or 50-Bigha holding, can shift the final acre or hectare figure enough to matter for a ceiling-law check or a per-acre price comparison — convert once, precisely, at the parcel's actual total size rather than rounding a per-unit figure first and multiplying the rounded number.
• Treating a broker's colloquial Bigha as identical to the khasra record's Bigha. In most cases they're the same figure, but where they diverge, the khasra record — not the verbal quote — is the one that will matter at registration, and it's worth pulling that record before, not after, you've agreed a price.
• Assuming a single "corridor-wide" Bigha exists at all. Everything in this guide points to the same conclusion: it doesn't. Every one of the mistakes above ultimately comes back to treating a locally defined figure as if it were a portable, universal one.

Confirming Your Bigha Figure Before You Buy

Given everything above, the practical rule for any purchase in this corridor is short: never rely on a single, remembered "1 Bigha = X" figure for an actual transaction — confirm the state- and district-specific number first. In practice, that means, roughly in order of reliability:

• Ask the local Patwari or Tehsildar directly. The revenue official responsible for the specific village's records will know the operative local conversion with certainty, and it costs nothing but a visit or a call.
• Pull the actual khasra record for the parcel. As covered in our companion guide, Khasra and Khatauni Explained, most khasra records already state area in the local traditional unit — compare that figure against what you've been told, rather than taking a verbal quote at face value.
• Check whether a state land-record portal publishes its own conversion table. Where one exists and is directly citable, it's the most authoritative source available; where it isn't, treat convergent secondary sources as a reasonable starting estimate instead, and say so plainly rather than implying a citation that wasn't actually verified.
• Use a converter tool as a starting estimate only, never a final figure. Farmland India's own unit converter is built around exactly the state- and district-level variation covered in this guide — but treat any converter's output, including ours, as a number to confirm rather than a number to contract on.
• Get the confirmed figure in writing before you calculate a final price. A verbal confirmation from a Patwari or broker is a good start, but the number that actually protects you is the one that ends up written into the sale deed and cross-checked against the khasra record at registration — treat everything before that point as a working estimate, however confident it sounds.

This same discipline matters even more directly if you're checking a multi-parcel holding against a state ceiling limit — see our state-by-state agricultural land rules guide for how those limits are actually expressed, always in hectares or acres, never in Bigha.

How Farmland India Helps

Every Farmland India Reviewed listing in this corridor states its area in both the seller's local unit and a standard metric reference — acres and hectares — cross-checked against the parcel's own khasra record, so you're never left converting a verbal Bigha quote yourself. This guide, along with the district-level detail in our Uttar Pradesh deep-dive, is the reference material behind that cross-check.
