Buying a plot, reviewing a property deed, or dividing inherited land often requires comparing traditional and modern measurement units. Records may use Shatak or Decimal, Katha, and Bigha, while architects, developers, engineers, and municipal offices work in square feet or square meters. A small conversion mistake can affect valuation, construction planning, or a family partition.
The free PDF Studio Land Area Converter lets you convert between common units in real time. Enter a known value, select its unit, and review the equivalent area across the other units without doing the calculations manually.
Common Land-Area Units
Square Feet
Square feet are widely used for homes, apartments, boundary plans, construction estimates, and commercial spaces. Contractors and interior designers often need area in square feet to calculate usable space and material quantities.
Shatak or Decimal
In Bangladesh property records, Shatak and Decimal commonly refer to the same unit. Under the standard legal relationship, one Decimal is one hundredth of an Acre, or 435.6 square feet.
Katha
Katha is commonly used for urban and residential plots. A frequently used Bangladesh standard defines one Katha as 720 square feet, which is approximately 1.65 Decimals. Regional conventions can differ, so compare the result with the deed or local land office.
Bigha
Bigha is often used for agricultural or larger areas. Under the common standard described above, one Bigha equals 20 Katha, or about 14,400 square feet. Local historical definitions may vary, so never rely on a generic conversion for a legal transfer without verification.
Acre and Hectare
An Acre equals 43,560 square feet and 100 Decimals. A Hectare is an international metric unit equal to approximately 2.471 Acres. These units are useful for agricultural land, large developments, and official surveys.
Why Local Definitions Matter
Traditional units such as Katha and Bigha may have different values in different regions or historical records. A deed may also use a local convention that differs from a general online reference. Treat the converter as a calculation aid, then confirm the applicable standard with the land registry, surveyor, lawyer, or municipal authority handling the property.
Use the unit stated in the official document as your starting point. Keep the original deed, Khatian, Porcha, mutation record, and survey documents available when comparing results.
Why Local Calculation Protects Property Information
Land measurements can reveal details about family estates, planned purchases, commercial projects, and inheritance distributions. Entering those figures into an unknown property website may expose private information or invite unwanted marketing.
Local calculation also makes the result available immediately on a computer or phone without creating an account.
How to Convert Land Area Units
- Open the tool: Visit the PDF Studio Land Area Converter.
- Enter the value: Type the known area, such as 5.5.
- Select the source unit: Choose Katha, Shatak, Bigha, Acre, Square Feet, Square Meters, or another available unit.
- Review the results: Compare the equivalent values across the supported units.
- Record the result: Copy the required figure into a planning note, valuation worksheet, or draft calculation.
Keep enough decimal places for your purpose. Round only after the calculation, and state the unit beside every number so a reader cannot confuse Katha with Decimal or square feet.
Real-World Uses
Apartment buyers can compare an Undivided Land Share stated in Decimal or Katha with the project's square-foot information. Families can convert inherited land before discussing a fair partition. Bank and mortgage teams can check that valuation documents use consistent units. Developers and architects can translate deed measurements into square feet or square meters for early planning.
Conversion does not replace a boundary survey. A unit calculation tells you the area, but only an authorized survey and official records can establish the legal location and boundaries of a property.
Verification Checklist
- Confirm the region's definition of Katha, Bigha, or another traditional unit.
- Compare the converted figure with the original deed and survey records.
- Write the unit beside every value in contracts and calculations.
- Keep unrounded values during intermediate calculations.
- Ask a qualified surveyor or legal professional to verify numbers used in a transaction.
