How to Convert Biswa to Square Feet

Biswa to square feet conversion is simple once the local square-foot value of one biswa is known. The general formula is:

For the common North India profile used on this page by default, the multiplier is 1,350. Therefore:

If you have 5 biswa, the calculation is \(5\times1{,}350=6{,}750\text{ sq ft}\). If you have 10 biswa, the calculation is \(10\times1{,}350=13{,}500\text{ sq ft}\). If you have 20 biswa, the result is \(20\times1{,}350=27{,}000\text{ sq ft}\), which equals 1 bigha in the same profile.

To convert square feet back to biswa, divide by the square-foot value of one biswa:

For the 1,350 profile, \(5{,}000\div1{,}350\approx3.7037\) biswa. The reverse calculation is important because many property listings and building plans use square feet while local land conversations use biswa or bigha.

What Is a Biswa?

Biswa is a traditional land area unit used in parts of North India. It is commonly connected to bigha, with the relationship \(1\text{ bigha}=20\text{ biswa}\) in many systems. The word is especially common in rural and semi-urban land discussions where farmland, inherited land, village plots and smaller land parcels are described in bigha and biswa rather than only in square feet or square meters.

The difficult part is that biswa is not a single national measurement. Its value changes according to the local bigha definition. If the bigha is 27,000 square feet, one biswa is \(27{,}000\div20=1{,}350\) square feet. If the bigha is 27,225 square feet, one biswa is \(27{,}225\div20=1{,}361.25\) square feet. If the bigha is 8,100 square feet, one biswa is 405 square feet. These are not arithmetic contradictions; they are different regional definitions.

For ordinary learning and many North India property references, 1,350 square feet per biswa is a useful default. For legal, tax, inheritance, loan, valuation or construction decisions, the value in the official record should control. The calculator is designed around that reality: use the default when it matches the document, choose another profile when the local value is known, or enter a custom value when the record states a specific conversion.

North India Biswa Profiles

The default profile on this page is \(1\text{ biswa}=1{,}350\text{ sq ft}\), which gives \(1\text{ bigha}=20\text{ biswa}=27{,}000\text{ sq ft}\). This profile is often used for North India examples and is common in Uttar Pradesh land-unit explanations. It also gives a convenient gaj relationship: \(1{,}350\div9=150\text{ gaj}\).

Another common nearby profile is \(1\text{ bigha}=27{,}225\text{ sq ft}\), which gives \(1\text{ biswa}=1{,}361.25\text{ sq ft}\). This value appears where bigha is aligned with 3,025 square yards because \(3{,}025\times9=27{,}225\). It is close to the 1,350 profile but not identical. The difference is 11.25 square feet per biswa, or 225 square feet per 20 biswa.

Smaller bigha systems also exist. A bigha of 900 square yards equals 8,100 square feet, so one biswa is 405 square feet if the same \(20\text{ biswa}=1\text{ bigha}\) relationship is used. A bigha of 968 square yards equals 8,712 square feet, so one biswa is 435.6 square feet. These examples show why a converter should not hide the conversion factor from the reader.

If a property document gives a value such as "1 biswa = 151.25 square yards," convert square yards to square feet by multiplying by 9: \(151.25\times9=1{,}361.25\text{ sq ft}\). If it gives "1 biswa = 150 gaj," and gaj is being used as square yard, the square-foot value is \(150\times9=1{,}350\text{ sq ft}\). The key is to reduce the local unit to square feet before comparing it with other land areas.

Biswa Conversion Reference Table

The table below uses the common 1,350-square-foot North India profile. Use it for quick checks, then use the calculator above if your local record uses 1,361.25, 405, 435.6 or another biswa value.

Core Biswa Conversion Formulas

Biswa to square feet

Use 1,350 for the common North India profile. Use 1,361.25, 405, 435.6 or another value only when that is the relevant local or document value.

Square feet to biswa

Biswa to bigha

This formula assumes the local system uses 20 biswa in 1 bigha. In many North India contexts that relationship is expected, but the square-foot value of the bigha still depends on the selected profile.

Biswa to gaj

If 1 biswa equals 1,350 square feet, it equals \(1{,}350\div9=150\) gaj. If 1 biswa equals 1,361.25 square feet, it equals 151.25 gaj. For a focused square-yard calculation, use the gaj to square feet converter.

Biswa to acre

At 1,350 square feet per biswa, \(1\text{ biswa}=1{,}350\div43{,}560\approx0.030992\) acre. Therefore, 20 biswa equals \(27{,}000\div43{,}560\approx0.619835\) acre.

Biswa to square meters and hectares

At the 1,350 profile, one biswa is about 125.41935 square meters and 0.01254194 hectare. Metric conversion is useful when a record, map, survey or planning note uses square meters while the local discussion uses biswa.

Worked Examples

Worked examples make the profile issue clear. Every example below states the conversion factor before doing the arithmetic. This is the safest habit when using traditional land units because the same word can represent different areas in different places.

Example 1: Convert 5 biswa to square feet

Using \(1\text{ biswa}=1{,}350\text{ sq ft}\):

If the property document uses the 1,361.25 profile, the same 5 biswa equals \(5\times1{,}361.25=6{,}806.25\text{ sq ft}\). The difference is 56.25 square feet. That may be small for agricultural land, but it can matter for a residential plot, boundary estimate or price calculation.

Example 2: Convert 10 biswa to square feet

Using the 1,350 profile:

Ten biswa is half a bigha if 20 biswa equals 1 bigha. That makes mental checking easy: half of 27,000 square feet is 13,500 square feet.

Example 3: Convert 20 biswa to bigha and square feet

This is the anchor value for the default calculator profile. If your local bigha is not 27,000 square feet, change the profile before relying on this answer.

Example 4: Convert 5,000 square feet to biswa

Reverse conversion uses division:

If rounded for a listing conversation, this is about 3.70 biswa. If used in a document check, keep the square-foot value and write the precise conversion factor beside the calculation.

Example 5: Convert 1 hectare to biswa

One hectare equals 10,000 square meters. Since \(1\text{ sq m}=10.7639104167\text{ sq ft}\):

So 1 hectare is about 79.73 biswa in the 1,350-square-foot profile. If a local bigha or biswa profile differs, the biswa answer also changes.

Example 6: Convert 150 gaj to biswa

First convert gaj to square feet, using \(1\text{ gaj}=9\text{ sq ft}\):

Then divide by the biswa profile:

Under the 1,361.25-square-foot profile, the same 150 gaj would be \(1{,}350\div1{,}361.25\approx0.9917\) biswa.

Biswa and Bigha

Biswa is normally a subunit of bigha. In many North India systems, \(1\text{ bigha}=20\text{ biswa}\). This relationship is easy to use: 5 biswa is one quarter bigha, 10 biswa is half a bigha, 15 biswa is three quarters bigha, and 20 biswa is one full bigha.

The square-foot value of one bigha changes by region. If 1 biswa is 1,350 square feet, one bigha is 27,000 square feet. If 1 biswa is 1,361.25 square feet, one bigha is 27,225 square feet. If 1 biswa is 405 square feet, one bigha is 8,100 square feet. This is why a bigha conversion should not be copied from one state to another without checking the local definition.

If your calculation starts with bigha rather than biswa, the bigha to acre converter is usually the better starting point. Use this page when the main value is in biswa or when you need to convert square feet back into biswa.

Biswa and Gaj

Gaj is commonly treated as square yard in property conversations. One gaj equals 9 square feet. Therefore, the gaj value of one biswa depends on the square-foot value of the biswa. In the 1,350 profile, one biswa equals 150 gaj. In the 1,361.25 profile, one biswa equals 151.25 gaj. In the 405-square-foot profile, one biswa equals 45 gaj.

Use this relationship when a seller gives land area in gaj but the local record uses biswa. First convert gaj to square feet, then convert square feet to biswa using the local factor. Do not assume that 150 gaj always equals one biswa unless the selected profile is 1,350 square feet per biswa.

Biswa and Marla

Marla is another land unit used in North India and Pakistan, especially in Punjab, Haryana and neighboring property markets. The conversion from biswa to marla depends on both the biswa profile and the marla profile. Under the 1,350-square-foot biswa profile and the 272.25-square-foot marla profile:

Under the 225-square-foot marla profile:

These two answers are both mathematically valid because they use different marla definitions. If your work is primarily about marla, use the marla to square feet converter. If your work is about kanal and marla together, the kanal to marla converter is more focused.

Biswa, Acre and Hectare

Acre and hectare are useful for larger land parcels, agricultural holdings, planning reports and map-based comparisons. The acre relationship is based on 43,560 square feet per acre:

Using 1,350 square feet per biswa, one biswa is approximately 0.030992 acre and one bigha of 20 biswa is approximately 0.619835 acre. For acre-first problems, the acre to square feet converter gives a direct acre-to-square-foot bridge before you convert into biswa.

Hectare conversion uses the metric area standard. One hectare is 10,000 square meters. Because one square meter equals approximately 10.7639104167 square feet, one hectare equals about 107,639.104167 square feet. Under the 1,350 profile, that gives about 79.7327 biswa per hectare.

Using the Converter for Land Records

Land records may use traditional units, metric units or a mixture of both. A record may show bigha-biswa, a map may show square meters, a property listing may show square feet, and a local conversation may use gaj. The safest workflow is to convert each value into square feet first, then convert the square-foot total into the target unit.

If a record says 1 bigha 6 biswa, first convert the compound entry into total biswa. Since 1 bigha equals 20 biswa in the selected profile, \(1\text{ bigha }6\text{ biswa}=26\text{ biswa}\). Under the 1,350 profile, the square-foot area is \(26\times1{,}350=35{,}100\text{ sq ft}\). Under the 1,361.25 profile, it is \(26\times1{,}361.25=35{,}392.5\text{ sq ft}\).

If a record gives 0.5 bigha, convert to biswa first: \(0.5\times20=10\text{ biswa}\). Then multiply by the square-foot profile. This avoids confusion when one person thinks in bigha and another thinks in biswa.

For mixed Indian land units such as katha, dhur, decimal, cent, guntha, kanal and marla, the India land unit conversion table gives a broader reference. This page stays focused on biswa so that the calculator remains clear for the most common North India biswa-to-square-foot problem.

Using Biswa Conversion for Property Listings

Property listings often use the unit buyers expect locally. In a rural market, a listing may say 4 biswa, 8 biswa or 1 bigha rather than square feet. In an urban or semi-urban market, the same plot may be described in square feet or gaj. Converting biswa into square feet makes it easier to compare listings, calculate price per square foot and estimate construction potential.

Start by copying the listing value exactly. If the listing says 5 biswa, enter 5 and select the profile that matches the local area. If the listing says 0.25 bigha, enter 0.25 bigha and use the same profile. If it gives square feet, enter square feet and convert back to biswa. Then compare the result with the wording in the listing.

Next, compare dimensions. If a rectangular plot is 45 feet by 150 feet, its area is \(45\times150=6{,}750\text{ sq ft}\). Under the 1,350 profile, that is exactly 5 biswa. If the listing says 5 biswa and gives those dimensions, the arithmetic matches. If the listing says 5 biswa but the dimensions produce 5,400 square feet, the plot may be 4 biswa under the 1,350 profile, or the listing may be using another profile, approximate wording or an irregular shape.

For rectangle-first work, the rectangle area calculator can calculate the square-foot area before you convert the result into biswa. For learners who need the area step explained, the guide on how to calculate square feet is a useful companion.

Price Per Biswa and Price Per Square Foot

Land prices are often quoted per biswa or per bigha in local markets, but square-foot comparison is clearer when two listings use different units. The formula for price per square foot is:

If a 5 biswa plot costs 4,500,000 rupees under the 1,350 profile, its area is 6,750 square feet. The price per square foot is \(4{,}500{,}000\div6{,}750\approx666.67\) rupees per square foot.

To convert a price per biswa into price per square foot, divide by the square-foot value of one biswa:

If the rate is 900,000 rupees per biswa and the profile is 1,350 square feet per biswa, the square-foot rate is \(900{,}000\div1{,}350\approx666.67\). If another area uses 1,361.25 square feet per biswa at the same price per biswa, the square-foot rate is \(900{,}000\div1{,}361.25\approx660.55\). The difference is small in this example but can matter in larger transactions.

To convert price per square foot back to price per biswa:

This is useful when an urban listing gives square-foot rates but a local buyer wants to understand the value in biswa or bigha terms.

Construction Planning and Biswa

Construction planning usually requires square feet or square meters, not only biswa. A plot described as 2 biswa under the 1,350 profile is 2,700 square feet. The buildable area may be smaller because of setbacks, access requirements, road widening, open-space rules, boundary walls, drainage, parking and local development controls.

If a 2 biswa plot has 70 percent permissible ground coverage, the estimated ground coverage is \(2{,}700\times0.70=1{,}890\text{ sq ft}\). If the same 2 biswa label uses a 405-square-foot profile, the land area is 810 square feet and 70 percent coverage is only 567 square feet. The unit profile changes the planning context completely.

For irregular plots, split the land into simple shapes, calculate each area in square feet, add the parts, and then convert the total into biswa. If a land parcel has a rectangle plus a triangular corner, calculate rectangle area and triangle area separately. Do not convert each small part into rounded biswa values and then add them, because repeated rounding can distort the total.

For broader area-unit work beyond biswa, the area converter and advanced area converter can help compare standard units after the square-foot value is known.

Regional Variation and Document Priority

The most important rule for biswa conversion is document priority. If a government record, registered deed, survey map, local revenue note or official layout plan states the square-foot or square-meter value, use that value. If the document gives a bigha value and the local bigha definition, divide by 20 to find the biswa value. If the document gives only the word "biswa," confirm the local conversion before using it for price, sale, loan, tax, inheritance or construction decisions.

Online converters and tables are useful for arithmetic, but they cannot know every district practice or every historical record convention. A district may use pucca bigha, kucha bigha, local bigha, state revenue bigha or another named system. Some values differ only slightly, while others differ substantially. A result that is right for one state may be wrong for another.

The calculator handles this by showing the active profile and allowing custom input. If your record says one biswa equals 1,350 square feet, use the default. If it says one biswa equals 1,361.25 square feet, select that profile. If it says one biswa equals 45 square yards, either select the 405-square-foot profile or enter 405 as a custom value. If it states another figure, enter the stated figure directly.

Rounding Biswa Conversion Results

Rounding should match the purpose of the calculation. For quick conversation, 3.70 biswa is usually clearer than 3.7037037037 biswa. For a document check, keep the exact source number and the exact profile value. If the document says 5,000 square feet, do not replace it with a rounded biswa value and discard the original square-foot number.

When converting from biswa to square feet, whole-number results are common if the profile is whole-number square feet. For example, 7 biswa at the 1,350 profile is 9,450 square feet. When converting square feet to biswa, decimals are common. For example, 12,000 square feet is \(12{,}000\div1{,}350\approx8.8889\) biswa.

If a calculation involves multiple pieces, round only once at the end. Add all areas in square feet first. Then convert the total into biswa, bigha, acre or hectare. This avoids small errors that build up when each piece is rounded separately.

Common Mistakes to Avoid

The first mistake is treating 1 biswa as a universal value. The default 1,350-square-foot profile is useful, but it is not the only value used in India. The second mistake is using the correct biswa value but the wrong bigha relationship. If the local system does not use 20 biswa per bigha, the bigha result must be adjusted.

The third mistake is confusing gaj with square feet. If gaj means square yard, multiply by 9 to get square feet. The fourth mistake is comparing price per biswa from two regions without converting both to price per square foot. The fifth mistake is using plot area as if it were built-up area. A land parcel of 5 biswa does not mean the full 5 biswa can be built on every floor.

The sixth mistake is ignoring irregular shape. Frontage and depth may not describe the full land area if a plot is tapered, has a missing corner, includes a road deduction or follows a non-rectangular boundary. The seventh mistake is depending on a casual listing when an official record is available. Use the calculator to check arithmetic, then verify important decisions with reliable local records.

Verification Workflow

1. Identify the source of the area: listing, deed, survey, map, revenue record, valuation note or classroom problem.
2. Write the starting unit exactly: biswa, bigha, square feet, gaj, acre, hectare, square meters, marla or kanal.
3. Choose the local biswa profile or enter the custom square-foot value stated by the document.
4. Convert the value to square feet.
5. Check the reverse conversion by dividing square feet by the same profile.
6. Compare with dimensions if length and width are available.
7. Use square feet for price per square foot, material planning and cross-listing comparison.
8. Use official records and qualified local advice before relying on the number for a formal transaction.

How to Choose a Biswa Profile in Practice

Choosing the correct biswa profile is more important than pressing the convert button. The most reliable source is the document that created or describes the land right. That may be a sale deed, registry extract, khasra or khatauni record, allotment letter, mutation note, survey sheet, village revenue map, court document, family partition record or approved layout plan. If the document gives square feet, square meters, bigha or gaj along with biswa, use those numbers to identify the implied profile.

For example, if a record says 1 bigha equals 27,000 square feet and 1 bigha equals 20 biswa, then one biswa is:

If a record says 1 bigha equals 27,225 square feet, then one biswa is:

If a record states square yards instead, convert square yards to square feet first. A bigha of 3,000 square yards equals \(3{,}000\times9=27{,}000\) square feet, so one biswa is 1,350 square feet. A bigha of 3,025 square yards equals \(3{,}025\times9=27{,}225\) square feet, so one biswa is 1,361.25 square feet.

When no conversion factor is stated, check local practice instead of guessing. A village revenue office, local surveyor, licensed deed writer, district record room or experienced local property professional may know which value is normally used in that area. The answer can differ even within a broad region because traditional units were shaped by local revenue history. A converter should support arithmetic, but it cannot replace the local definition.

It is also sensible to keep a written note of the profile used. Instead of writing only "6 biswa = 8,100 sq ft," write "6 biswa at 1,350 sq ft per biswa = 8,100 sq ft." That one phrase makes the calculation auditable. If another person uses 1,361.25 square feet per biswa, the reason for the different answer becomes immediately visible.

Reverse Conversion Examples

Many users arrive with square feet and need the local biswa label. Reverse conversion is common when a property plan, municipal record, valuation sheet or construction drawing gives square feet, while a buyer or seller wants to discuss the land in biswa. The reverse formula is:

Convert 2,700 square feet to biswa

Using the 1,350 profile:

Using the 1,361.25 profile:

The two answers are close but not identical. For quick conversation they may both sound like about 2 biswa, but formal work should use the profile from the record.

Convert 9,000 square feet to biswa

Using the 1,350 profile, \(9{,}000\div1{,}350\approx6.6667\) biswa. This is one third of a bigha if 20 biswa equals 1 bigha, because \(6.6667\div20\approx0.3333\) bigha. Using the 1,361.25 profile, \(9{,}000\div1{,}361.25\approx6.6116\) biswa.

Convert 54,000 square feet to biswa

Using the 1,350 profile:

Since 20 biswa equals 1 bigha in this profile, 40 biswa equals 2 bigha. This type of reverse check is useful when an acre-sized parcel is described in square feet and the local discussion uses bigha-biswa.

Checking Dimensions Against Biswa

Dimension checks help identify whether a listed biswa value is plausible. For a rectangular plot, area is length multiplied by width:

Suppose a plot is listed as 30 feet wide and 90 feet deep. The area is \(30\times90=2{,}700\text{ sq ft}\). Under the 1,350 profile, this is exactly 2 biswa. If the listing calls it 2 biswa, the dimensions and unit label match. If the listing calls it 3 biswa, ask whether the dimensions are approximate, whether a rear portion is omitted, or whether the profile is different.

Suppose another plot is 50 feet by 135 feet. The area is \(50\times135=6{,}750\text{ sq ft}\). Under the 1,350 profile, this is exactly 5 biswa. This kind of clean match is common in examples, but real plots may have uneven sides, road cuts, curved boundaries or non-rectangular shapes.

For non-rectangular land, calculate the square-foot area from the shape before converting. A triangular portion uses \( \frac{1}{2}\times\text{base}\times\text{height} \). A trapezoid uses \( \frac{1}{2}\times(a+b)\times h \), where \(a\) and \(b\) are the parallel sides. Add all parts in square feet, then convert the total into biswa. This keeps the conversion clean and avoids rounding each small piece separately.

When a survey plan gives meters, calculate square meters first and then convert to square feet. A rectangle that is 20 meters by 30 meters has area \(20\times30=600\text{ sq m}\). In square feet, that is \(600\times10.7639104167\approx6{,}458.35\text{ sq ft}\). Under the 1,350 profile, it is \(6{,}458.35\div1{,}350\approx4.784\) biswa.

Biswa Conversion in Agricultural Land

Agricultural land is often described in larger traditional units, but biswa remains useful for partial holdings, field divisions, inheritance shares and sale portions. If a family holding is 2 bigha 8 biswa, the total is \(2\times20+8=48\) biswa. Under the 1,350 profile, the square-foot area is \(48\times1{,}350=64{,}800\text{ sq ft}\). In acres, that is \(64{,}800\div43{,}560\approx1.4876\) acres.

If the same land is split equally among three heirs, each share is \(48\div3=16\) biswa. Under the same profile, each share is \(16\times1{,}350=21{,}600\text{ sq ft}\). In bigha terms, 16 biswa is 0.8 bigha. The arithmetic is straightforward, but it depends entirely on using one consistent local profile across the whole calculation.

For agricultural comparisons, hectare conversion may also appear in government schemes, land-use reports or map documents. Under the 1,350 profile, 80 biswa is 108,000 square feet, which is about 10,033.55 square meters or about 1.0034 hectare. That is why people sometimes use "about 80 biswa" as a rough mental bridge for 1 hectare in this profile, though the precise result is about 79.73 biswa.

Biswa Conversion in Residential Plot Planning

In residential planning, biswa is often converted to square feet because building layouts, room sizes, setbacks, parking areas, staircases, septic systems, courtyards and boundary walls are normally designed in feet or meters. A 1 biswa plot under the 1,350 profile is much larger than many urban plots. It could support a substantial residential layout if local zoning permits, but the usable footprint still depends on regulations and site shape.

For a 1 biswa plot, if only 60 percent of the land can be covered on the ground floor, the ground coverage is \(1{,}350\times0.60=810\text{ sq ft}\). For a 2 biswa plot, it is \(2{,}700\times0.60=1{,}620\text{ sq ft}\). For a 5 biswa plot, it is \(6{,}750\times0.60=4{,}050\text{ sq ft}\). These numbers are planning examples only; local building rules determine the actual permitted coverage.

If a plot is priced in biswa but construction is estimated per square foot, convert land area and building area separately. Land area tells you plot size. Built-up area tells you construction quantity. They are related but not identical. A larger land parcel can have a smaller built-up area if setbacks are large, and a smaller parcel can have more total built-up area if multiple floors are allowed.

Practice Questions

Use these examples to test the conversion process. Unless a different profile is stated, assume \(1\text{ biswa}=1{,}350\text{ sq ft}\).

1. Convert 3 biswa to square feet. Answer: \(3\times1{,}350=4{,}050\text{ sq ft}\).
2. Convert 12 biswa to bigha. Answer: \(12\div20=0.6\text{ bigha}\).
3. Convert 8,100 square feet to biswa. Answer: \(8{,}100\div1{,}350=6\text{ biswa}\).
4. Convert 750 gaj to biswa. Since \(750\times9=6{,}750\text{ sq ft}\), the result is \(6{,}750\div1{,}350=5\text{ biswa}\).
5. Convert 0.25 hectare to biswa. Since \(0.25\text{ ha}=2{,}500\text{ sq m}\), square feet are \(2{,}500\times10.7639104167\approx26{,}909.78\). Divide by 1,350 to get about 19.93 biswa.
6. Convert 2 bigha 5 biswa to square feet. Total biswa is \(2\times20+5=45\). Square feet are \(45\times1{,}350=60{,}750\text{ sq ft}\).

When solving your own problems, write the factor first. A clear line such as "using 1,350 square feet per biswa" prevents most mistakes. If the question provides a different local conversion, replace 1,350 with that value throughout the calculation. Keep the original source area beside the converted value for clear review later.
