How to Convert Bigha to Acre

Bigha to acre conversion is a two-step calculation. First, convert bigha into square feet using the state or local bigha profile. Second, divide the square-foot result by 43,560 because one acre is exactly 43,560 square feet.

Combining those two steps gives the direct formula:

For example, using a 27,000-square-foot bigha, \(1\text{ bigha}=27{,}000\div43{,}560\approx0.619835\text{ acre}\). Using a 14,400-square-foot bigha, \(1\text{ bigha}=14{,}400\div43{,}560\approx0.330579\text{ acre}\). Using a 9,070-square-foot bigha, \(1\text{ bigha}=9{,}070\div43{,}560\approx0.208218\text{ acre}\).

The acre value is not attached to the word bigha alone. It is attached to the square-foot profile behind the word bigha. That is why this calculator asks for a state or custom profile before showing acre results.

What Is a Bigha?

Bigha is a traditional land area unit used in several parts of India and nearby regions. It is common in agricultural land transactions, rural property records, family inheritance discussions, village land descriptions, and older revenue systems. In many places, people still say a plot is 1 bigha, 2 bigha or 5 bigha even when official records also show square meters, hectares, acres or square feet.

The challenge is that bigha is regional. A bigha in one state may not equal a bigha in another state. Even within a state, district practice, pucca and kachha distinctions, older records, local land categories and revenue conventions can create different values. A state-wise calculator is therefore more useful than a calculator that assumes one bigha value for every user.

For calculation purposes, square feet is the bridge unit. Once a bigha profile is expressed in square feet, it can be converted into acre, hectare, square meters, gaj, biswa, marla or kanal. If you are comparing land across states, convert each property into square feet or acres first, then compare.

State-wise Bigha Values

The table below lists common bigha profiles used for calculation and comparison. Treat these as practical conversion profiles, not a substitute for a district land record. If a deed, survey or official portal gives a specific value, use that value in the custom field.

Core Bigha Conversion Formulas

Bigha to square feet

This is the base step. If the selected bigha profile is 27,000 square feet, 5 bigha equals \(5\times27{,}000=135{,}000\text{ sq ft}\). If the selected profile is 14,400 square feet, 5 bigha equals \(5\times14{,}400=72{,}000\text{ sq ft}\).

Bigha to acre

Use this when the goal is land comparison in acres. For acre-first calculations, use the acre to square feet converter and then convert square feet into bigha with the selected state profile.

Acre to bigha

For example, 1 acre in the 27,000 profile equals \(43{,}560\div27{,}000\approx1.6133\) bigha. In the 14,400 profile, 1 acre equals \(43{,}560\div14{,}400=3.025\) bigha.

Bigha to hectare

Hectare conversion is useful because many official and planning documents use metric area units. One hectare equals 10,000 square meters.

Bigha to gaj

When gaj is used as square yard, 1 gaj equals 9 square feet. For focused gaj calculations, use the gaj to square feet converter.

Bigha to biswa

This relationship applies where the local system uses 20 biswa in one bigha. If your local record uses a different subdivision, change the interpretation accordingly. For biswa-first calculations, use the biswa to square feet converter.

Worked Examples

Worked examples show why state-wise selection matters. The method is the same in every example, but the square-foot profile changes the answer.

Example 1: Convert 1 bigha to acre in Uttar Pradesh common profile

Using \(1\text{ bigha}=27{,}000\text{ sq ft}\):

So 1 bigha is about 0.62 acre in this profile. In the reverse direction, 1 acre is about \(43{,}560\div27{,}000\approx1.6133\) bigha.

Example 2: Convert 5 bigha to acre in West Bengal

Using \(1\text{ bigha}=14{,}400\text{ sq ft}\):

Five bigha in this profile is about 1.65 acres. Five bigha in a 27,000-square-foot profile would be 135,000 square feet, or about 3.10 acres, which is almost twice as much land.

Example 3: Convert 10 bigha to acre in Punjab profile

Using \(1\text{ bigha}=9{,}070\text{ sq ft}\):

Ten bigha in this profile is about 2.08 acres. This example is a good reminder that a "10 bigha" label can mean very different physical land area across regions.

Example 4: Convert 1 acre to bigha in Bihar profile

Using \(1\text{ bigha}=27{,}220\text{ sq ft}\):

So 1 acre is about 1.60 bigha in this profile. If a listing says 2 acres, it is about \(2\times1.600294=3.200588\) bigha.

Example 5: Convert 1 hectare to bigha in the 27,000 profile

One hectare equals 10,000 square meters. In square feet:

Then divide by 27,000:

That is why many quick explanations round 1 hectare to about 4 bigha in a 27,000-square-foot profile.

Example 6: Convert 3,000 gaj to bigha

If gaj is square yard, \(3{,}000\text{ gaj}=3{,}000\times9=27{,}000\text{ sq ft}\). In a 27,000-square-foot bigha profile, that is exactly 1 bigha. In a 14,400-square-foot bigha profile, it is \(27{,}000\div14{,}400=1.875\) bigha.

How to Choose the Correct State Profile

The safest source is the document that controls the land description. That may be a registered deed, revenue record, survey map, allotment letter, mutation record, khasra or khatauni entry, court record, family partition document, development authority plan or official measurement sheet. If the document states square feet or square meters, use that as the controlling area and convert from there.

If the document states a bigha value and a square-foot equivalent, calculate the profile by division. For example, if a document says 2 bigha equals 54,000 square feet, then one bigha is \(54{,}000\div2=27{,}000\) square feet. If it says 4 bigha equals 57,600 square feet, then one bigha is \(57{,}600\div4=14{,}400\) square feet.

If the document states bigha and biswa, first confirm the subdivision. Many North India systems use 20 biswa in 1 bigha. If the same document states one biswa equals 1,350 square feet, one bigha is \(20\times1{,}350=27{,}000\) square feet. If one biswa equals 1,361.25 square feet, one bigha is 27,225 square feet.

If no profile is stated, do not assume a value for legal or financial decisions. Ask a local revenue office, surveyor, deed writer, land records professional or qualified property adviser. Online tables are useful for checking arithmetic, but local records determine real property area.

Bigha, Biswa and Katha

Biswa and katha are common subunits related to bigha in many regions. The relationship is not identical everywhere, but many North India contexts use \(1\text{ bigha}=20\text{ biswa}\). In Bihar and Bengal-related systems, katha may be part of the local land-unit chain. Because these subunits vary, the cleanest calculation path is to convert everything to square feet.

For a 27,000-square-foot bigha with 20 biswa, one biswa is \(27{,}000\div20=1{,}350\) square feet. For a 27,225-square-foot bigha, one biswa is \(27{,}225\div20=1{,}361.25\) square feet. For a 14,400-square-foot bigha with 20 katha in a local system, one katha would be \(14{,}400\div20=720\) square feet if that subdivision is used. Always follow the local subdivision named in the source.

If your calculation starts with biswa, use the biswa to square feet converter. If it starts with bigha and the goal is acreage, this page is the better fit.

Bigha, Marla and Kanal

Marla and kanal are often used in Punjab, Haryana, Jammu and Kashmir, Himachal Pradesh, parts of North India and Pakistan-related property contexts. These units can overlap with bigha in conversation, but their relationships depend on local definitions. A common big marla is 272.25 square feet, while a common Pakistan urban marla is 225 square feet. Kanal is often 20 marla.

To compare bigha with marla, convert bigha to square feet and divide by the marla profile. In a 27,000-square-foot bigha, the number of 272.25-square-foot marla is \(27{,}000\div272.25\approx99.1736\). In a 9,070-square-foot bigha, the same comparison is \(9{,}070\div272.25\approx33.315\) marla. If using 225-square-foot marla, the values are different.

Use the marla to square feet converter for marla-first calculations and the kanal to marla converter for compound kanal-marla entries. This keeps each calculator focused on its own search intent.

Bigha and Gaj

Gaj is commonly treated as square yard in real estate conversations. Since \(1\text{ gaj}=9\text{ sq ft}\), the gaj value of one bigha is the bigha square-foot value divided by 9. A 27,000-square-foot bigha equals 3,000 gaj. A 27,225-square-foot bigha equals 3,025 gaj. A 14,400-square-foot bigha equals 1,600 gaj. A 9,070-square-foot bigha equals about 1,007.78 gaj.

This is useful when land prices are quoted per gaj while the plot area is described in bigha. Convert bigha to square feet, divide by 9 to get gaj, and then calculate the price. If the listing starts in gaj, convert gaj to square feet first and then divide by the selected bigha profile.

Using Bigha Conversion for Property Listings

Property listings often use familiar local units because buyers and sellers understand them quickly. A listing may say 3 bigha, 5 bigha or 10 bigha without showing acres. That may be enough for local conversation, but it is not enough for cross-state comparison. The same bigha number can represent very different acreage depending on the profile.

Start by copying the listing value exactly. Choose the profile that matches the location and record. Convert the area to square feet and acres. Then compare with nearby listings using the same basis. If one listing is in bigha and another is in acres, convert both to square feet or both to acres before comparing size or price.

When dimensions are available, calculate the area from length and width. For a rectangular plot, \( \text{area}=\text{length}\times\text{width} \). If a plot is 150 feet by 180 feet, it is \(150\times180=27{,}000\) square feet. That is 1 bigha in the 27,000 profile and 1.875 bigha in the 14,400 profile. For rectangle-first work, use the rectangle area calculator or the guide on how to calculate square feet.

Price Per Bigha and Price Per Acre

Price comparisons become clearer when all values use the same area basis. A seller may quote price per bigha, while a buyer may compare price per acre. The conversion depends on the selected bigha profile.

If a 27,000-square-foot bigha is priced at 2,000,000, the acre-per-bigha value is about 0.619835. The price per acre is \(2{,}000{,}000\div0.619835\approx3{,}226{,}667\). If a 14,400-square-foot bigha is priced at 2,000,000, the acre-per-bigha value is about 0.330579 and the price per acre is about 6,049,999. The same price per bigha is not the same price per acre when the bigha size differs.

To find price per square foot:

Square-foot pricing is especially useful when comparing agricultural land with development land, plots with different shapes, or properties listed in different regional units.

Agricultural Land and Metric Records

Agricultural land may be described in bigha by local users and in hectare by official or planning documents. Metric records are common because hectare and square meter are standardized units. When a record gives hectare but a local discussion uses bigha, convert hectare to square feet first, then divide by the bigha profile.

For the 27,000 profile, 1 hectare is about 3.9866 bigha. For the 14,400 profile, 1 hectare is about 7.4749 bigha. For the 9,070 profile, 1 hectare is about 11.8676 bigha. The same hectare is a fixed metric area, but the bigha count changes with the local bigha definition.

For broad area conversions beyond bigha, use the area converter or advanced area converter. For general unit resources, the unit conversion calculator chart, unit converters page and converters page provide wider navigation.

Regional Notes for Common Profiles

Uttar Pradesh is often shown with a 27,000-square-foot bigha in calculator tables, but local UP usage can vary. Some references describe eastern, western, pucca and kucha relationships. If the record says 20 biswa of 1,361.25 square feet each, use 27,225 square feet. If the source says 27,000 square feet, use 27,000.

Bihar is commonly shown near 27,220 or 27,225 square feet, but katha and dhur values can vary by district. A Bihar record that gives katha or dhur should be converted through the local values stated in that record. Do not assume that a katha from one district matches a katha from another district.

West Bengal and Assam are often shown with 14,400 square feet per bigha, which equals 1,600 square yards. In these profiles, 1 acre is about 3.025 bigha. This is very different from the 27,000-square-foot profile, where 1 acre is about 1.61 bigha.

Punjab, Himachal Pradesh and Uttarakhand have commonly cited smaller bigha profiles. Punjab is often shown as 9,070 square feet in calculator tables, while Himachal Pradesh is often shown as 8,712 square feet. Uttarakhand may show different hilly and plain values. These are profile choices for calculation, not a replacement for a local land record.

Rajasthan may distinguish pucca bigha and kachha bigha. The pucca profile is often shown as 27,225 square feet, while the kachha profile is often shown as 17,424 square feet. If a Rajasthan document names pucca or kachha, choose the matching profile.

Common Mistakes to Avoid

The first mistake is using one bigha value for every state. Bigha varies too much for that. The second mistake is converting bigha directly to acre without first identifying the square-foot profile. The third mistake is comparing price per bigha across states without converting to price per acre or price per square foot.

The fourth mistake is treating rounded examples as legal values. A page may say 1 bigha is about 0.62 acre, but the exact value for a 27,000-square-foot bigha is about 0.619835 acre. Rounded figures are fine for quick understanding, but formal work should keep the original area and the exact factor.

The fifth mistake is ignoring document hierarchy. A casual listing, broker note, website table and official record may not carry the same authority. Use the calculator to check arithmetic, then verify the actual land area against the proper record before making a purchase, sale, loan, tax, inheritance or construction decision.

Verification Workflow

1. Identify the source of the land area: listing, deed, survey, revenue record, map, valuation note or classroom problem.
2. Write the starting value and unit exactly as given.
3. Choose the state or custom bigha profile that matches the source.
4. Convert bigha to square feet using the selected profile.
5. Divide square feet by 43,560 to get acres.
6. Reverse-check by multiplying acres by 43,560 and dividing by the same bigha profile.
7. Compare dimensions if length and width are available.
8. Keep the original source area beside the converted answer.
9. Verify official decisions with local records and qualified guidance.

Practice Questions

Use these questions to test the method. Unless a different profile is stated, use \(1\text{ acre}=43{,}560\text{ sq ft}\) and follow the bigha profile named in the question.

1. Convert 2 bigha to acre using the 27,000 profile. Answer: \(2\times27{,}000\div43{,}560\approx1.2397\text{ acre}\).
2. Convert 3 bigha to acre using the 14,400 profile. Answer: \(3\times14{,}400\div43{,}560\approx0.9917\text{ acre}\).
3. Convert 1 acre to bigha using the 9,070 profile. Answer: \(43{,}560\div9{,}070\approx4.8026\text{ bigha}\).
4. Convert 5 bigha to square feet using the 12,000 profile. Answer: \(5\times12{,}000=60{,}000\text{ sq ft}\).
5. Convert 10,000 square meters to bigha using the 27,000 profile. Answer: \(10{,}000\times10.7639104167\div27{,}000\approx3.9866\text{ bigha}\).
6. Convert 3,025 gaj to bigha using the 27,225 profile. Answer: \(3{,}025\times9=27{,}225\text{ sq ft}\), so the result is 1 bigha.

Reverse Conversion: Acre to Bigha by Profile

Many users do not start with bigha. They start with acres because agricultural land, bank valuation reports, project summaries and comparison listings often use acre. Reverse conversion uses the same profile in the opposite direction:

In the 27,000-square-foot profile, 1 acre is about 1.6133 bigha. In the 27,225-square-foot profile, 1 acre is exactly 1.6 bigha because \(27{,}225\times1.6=43{,}560\). In the 14,400-square-foot profile, 1 acre is 3.025 bigha. In the 9,070-square-foot profile, 1 acre is about 4.8026 bigha. In the 8,712-square-foot profile, 1 acre is exactly 5 bigha.

These reverse values are useful when a listing says "2 acres" but the local market discusses land in bigha. For example, 2 acres in a 27,000 profile is \(2\times43{,}560\div27{,}000\approx3.2267\) bigha. The same 2 acres in a 14,400 profile is \(2\times43{,}560\div14{,}400=6.05\) bigha. The acres are identical, but the bigha count changes because the bigha profile changes.

Reverse conversion also helps spot listing errors. If a broker says a plot is 1 acre and 1 bigha in the same sentence, those two labels may not match unless the local bigha equals one acre, which is not true for the common profiles in this calculator. A 1 acre plot is about 1.61 bigha in a 27,000 profile, 3.025 bigha in a 14,400 profile, and 5 bigha in an 8,712 profile.

More State Profile Guidance

State labels are helpful, but the document profile is still the highest priority. A state may contain more than one local bigha usage. Some areas distinguish pucca bigha from kachha bigha. Some districts use local katha, dhur, biswa or nali values. Some online tables round a value for convenience. For this reason, the calculator treats each selection as a profile, not as a legal declaration.

For Uttar Pradesh, a 27,000-square-foot profile is widely used in conversion calculators and property examples. However, many explanations also mention values based on 20 biswa of 1,361.25 square feet, giving 27,225 square feet. Western and eastern districts can be described differently in older or local explanations. When an UP record provides the square-foot value, use it directly.

For Bihar and Jharkhand, values near 27,220 and 27,211 square feet are common in state-wise tables. These are close to the 27,225 profile but not identical. If the conversion is for study, price comparison or a broad estimate, the preset is useful. If the conversion is for a deed, partition, bank loan or boundary decision, use the value in the document or confirm the district standard.

For West Bengal and Assam, the 14,400-square-foot profile is a common reference. It gives 1 acre = 3.025 bigha. This profile is much smaller than a 27,000-square-foot bigha, so direct bigha-to-bigha comparison with North Indian values can be misleading. Ten bigha in West Bengal at 14,400 square feet is 144,000 square feet, while ten bigha at 27,000 square feet is 270,000 square feet.

For Rajasthan, the distinction between pucca and kachha bigha is especially important. A pucca profile of 27,225 square feet gives 0.625 acre per bigha. A kachha profile of 17,424 square feet gives exactly 0.4 acre per bigha. If a listing or record simply says "bigha" in a Rajasthan context, ask whether pucca or kachha is intended.

For Punjab, Himachal Pradesh and Uttarakhand, smaller bigha values are common in many conversion references. A small bigha profile can make a large bigha count correspond to fewer acres than a North India 27,000-square-foot profile. This matters when comparing farms, orchards, hill land, road frontage, family holdings or compensation values.

Using the Custom Bigha Field

The custom field exists because the safest conversion factor is the one stated by the source. If your record says one bigha equals 2,500 square meters, convert that to square feet first or enter the square-foot equivalent if it is already provided. If your source says one bigha equals 3,000 square yards, the square-foot value is \(3{,}000\times9=27{,}000\). If it says one bigha equals 1,600 square yards, the value is \(1{,}600\times9=14{,}400\).

If the record gives a compound relationship, derive the value carefully. Suppose the record says 1 bigha = 20 biswa and 1 biswa = 1,350 square feet. Then one bigha is \(20\times1{,}350=27{,}000\) square feet. Suppose it says 1 bigha = 20 katha and 1 katha = 720 square feet. Then one bigha is \(20\times720=14{,}400\) square feet.

Once the custom value is entered, all results are based on that one value. The acre result uses \(43{,}560\) square feet per acre, the hectare result uses square meters, and the gaj result uses 9 square feet per square yard. This keeps the calculation internally consistent even when the local bigha profile is unusual.

Checking Area from Dimensions

Dimensions provide a strong reality check. A rectangular parcel with a 150-foot frontage and 180-foot depth has area:

That is 1 bigha in the 27,000 profile, 0.9917 bigha in the 27,225 profile, 1.875 bigha in the 14,400 profile, and about 2.9779 bigha in the 9,070 profile. The physical plot did not change. Only the local name attached to the area changed.

A parcel measuring 120 feet by 120 feet has area \(120\times120=14{,}400\text{ sq ft}\). That is 1 bigha in the West Bengal and Assam profile, 0.5333 bigha in the 27,000 profile, and about 1.5877 bigha in the 9,070 profile. If a listing describes a 120 by 120 feet parcel as 1 bigha, it probably uses a 14,400-square-foot profile.

Irregular plots need a more careful approach. Split the land into rectangles, triangles or trapezoids, calculate each part in square feet, add the parts, and only then convert the final square-foot total into bigha and acre. If you convert each part into rounded bigha values first, repeated rounding can create avoidable differences.

For a triangular part, use \( \frac{1}{2}\times\text{base}\times\text{height} \). For a trapezoid, use \( \frac{1}{2}\times(a+b)\times h \), where \(a\) and \(b\) are the parallel sides. Once the total area is in square feet, the bigha and acre conversion is straightforward.

Land Records, Surveys and Local Use

A bigha calculator is useful for arithmetic, but land records decide the authoritative area. Official records may use hectares, square meters, acres, bigha, katha, biswa, kanal, marla or a combination of these. Older records may use traditional units, while newer records may store metric values. Survey maps may also show boundary measurements without giving a simple rectangle.

When a record and a listing disagree, do not force them to match by changing conversion factors. Instead, identify what each number represents. A listing may describe approximate market area. A survey may show measured area. A revenue record may use a local unit. A development plan may show net plot area after road widening or reserved land. Each source can be describing a different area basis.

For purchase, sale, inheritance, bank valuation, land acquisition, tax, compensation, court or construction decisions, use the calculator as a checking tool and then verify against the proper record. Keep screenshots or notes of the selected profile if you need to explain the arithmetic to another party.

Comparing Land Across States

Cross-state comparison is one of the main reasons to convert bigha to acre. A buyer comparing 5 bigha in one state with 5 bigha in another may think the properties are the same size. They are not necessarily the same. Five bigha at 27,000 square feet each is 135,000 square feet, or about 3.10 acres. Five bigha at 14,400 square feet each is 72,000 square feet, or about 1.65 acres. Five bigha at 9,070 square feet each is 45,350 square feet, or about 1.04 acres.

When comparing land across states, convert every listing into acres and square feet first. Acres are familiar for agricultural land, while square feet are useful for exact price and development comparisons. If price is quoted per bigha in two states, convert the quoted rate to price per acre before comparing. Otherwise, a cheaper price per bigha may actually be more expensive per acre.

For example, suppose land in State A costs 2,000,000 per bigha and uses a 27,000-square-foot bigha. The price per acre is about 3,226,667. Land in State B costs 1,400,000 per bigha and uses a 14,400-square-foot bigha. The price per acre is about \(1{,}400{,}000\div0.330579\approx4{,}234{,}722\). State B looks cheaper per bigha but is more expensive per acre.

When to Use Acre, Hectare or Square Feet

Use acre when comparing larger agricultural parcels, farm land, orchard land, institutional parcels, development land and cross-state listings. Acre is widely recognized and has a fixed square-foot value. Use hectare when working with metric government records, planning documents, agricultural reports or international comparisons. Use square feet when you need exact price, frontage-depth checks, building-area planning or small plot comparison.

Use bigha when the local market, land record or family discussion uses bigha. There is nothing wrong with bigha as a local unit; the risk comes from forgetting that it is regional. A clear conversion should name both the local unit and the profile: "3 bigha at 27,000 sq ft per bigha = 81,000 sq ft = about 1.86 acres."

For construction planning, square feet and square meters are usually more actionable than bigha. A builder needs the actual site area, setbacks, coverage limits, floor area, access, drainage, road width and shape. Bigha can describe the land category, but square feet or square meters drive most design calculations.

Additional Practice Scenarios

These scenarios combine units the way they often appear in real work.

1. A listing says 6 bigha in a 14,400-square-foot profile. Square feet are \(6\times14{,}400=86{,}400\). Acres are \(86{,}400\div43{,}560\approx1.9835\).
2. A buyer has 2.5 acres and wants the equivalent in the 27,225 profile. Bigha are \(2.5\times43{,}560\div27{,}225=4\).
3. A farm is 0.75 hectare. In square feet, it is \(0.75\times10{,}000\times10.7639104167\approx80{,}729.33\). In the 27,000 profile, it is about 2.990 bigha.
4. A plot is 1,600 gaj. Square feet are \(1{,}600\times9=14{,}400\). In the 14,400 profile, it is 1 bigha. In acres, it is \(14{,}400\div43{,}560\approx0.3306\).
5. A record shows 1 bigha 10 biswa and the profile uses 20 biswa in 1 bigha. Total bigha are \(1+10\div20=1.5\). At 27,000 square feet per bigha, area is \(1.5\times27{,}000=40{,}500\text{ sq ft}\), or about 0.9298 acre.

In every scenario, the reliable workflow is the same: reduce the source unit to square feet, then convert to acre, hectare or another comparison unit.

Quick Reliability Checklist

Before sharing or relying on a bigha conversion, check four items. First, name the state or local profile. Second, write the square-foot value used for one bigha. Third, show the acre formula with 43,560 square feet per acre. Fourth, keep the original source area beside the converted answer. A result written as "2 bigha = 1.24 acre" is less clear than "2 bigha at 27,000 sq ft per bigha = 54,000 sq ft = 1.2397 acre." The second version can be reviewed, corrected and traced back to the source.
