About the Plot & Land Area Converter
In India and South Asia, land measurements are uniquely multifaceted because modern real estate documents use metric and imperial units (such as square metres, square feet, and acres), while state revenue records, patwari registers, and agricultural deeds continue to use historical customary units. Because traditional land measurement systems originated regionally, customary units like Bigha and Biswa vary in definition across state lines (for example, a standard Uttar Pradesh pucca Bigha equals 27,225 sq ft with 20 Biswa per Bigha, while in West Bengal or Bihar it can differ). This tool uses standardized benchmark conversion factors based on 1 Square Foot = 1.0 base unit: 1 Square Yard (Gaj) = 9 sq ft, 1 Square Metre = 10.7639 sq ft, 1 Acre = 43,560 sq ft, 1 Hectare = 107,639 sq ft (10,000 m²), 1 Guntha = 1,089 sq ft (Western India / Maharashtra), 1 Cent = 435.6 sq ft (Southern India / Tamil Nadu, Kerala), 1 Marla = 272.25 sq ft (Northern India / Punjab, Haryana), and 1 Biswa = 1,361.25 sq ft.
Primary Applications
- Converting agricultural land records into square feet, square yards, and acres
- Translating regional customary units (Bigha, Biswa, Guntha, Cent) for property buyers
- Verifying property listings and broker quotations across different regional metrics
- Checking land area calculations for revenue registry and municipal building sanction applications
- Independent mathematical check of land survey reports and title deeds
Formula & Method
Key Variables & Parameters:
- 1 Guntha: 1089.0 sq ft (33 ft × 33 ft) = 101.17 sq metres
- 1 Bigha: Regional unit: Standard Pucca Bigha = 27225 sq ft; Bengal Bigha = 14400 sq ft
- 1 Acre: 43560 sq ft = 4046.86 sq metres = 40 Gunthas
- 1 Hectare: 10000 sq metres = 107639 sq ft = 2.471 Acres
Land area conversion normalizes all regional and international measurement units to standard square feet (or square metres) as a common denominator before projecting into the desired target unit.
How This Calculator Works
Enter project-specific parameters into the designated input fields. The calculation engine standardizes numerical values, verifies boundary conditions, and computes all results in real time. Results update automatically as you change inputs.
- Enter the numerical land or plot area value in the "Area value" input field.
- Select your starting source measurement unit from the "From unit" dropdown (e.g. Acre, Bigha, Guntha, Cent, Square Yards/Gaj, or Square Feet).
- Review the comprehensive conversion table below, which instantly calculates and highlights the exact equivalent area across all 10 supported units.
- Use the converted figures for preliminary property comparisons, verifying land broker claims, reviewing municipal building bylaws, or checking revenue registry documentation.
Worked Example: Converting 1.5 Acres of Agricultural Land to Regional Units
Scenario: An investor is purchasing a 1.5-acre parcel of land in Uttar Pradesh and needs to verify its equivalent area in Square Feet, Square Yards (Gaj), Bigha, and Guntha.
- 1. Base area in Square Feet: 1 Acre = 43,560 sq ft. For 1.5 Acres = 1.5 × 43,560 = 65,340 sq ft.
- 2. Convert to Square Yards (Gaj): 65,340 sq ft ÷ 9 sq ft/sq yd = 7,260.00 sq yd (Gaj).
- 3. Convert to Square Metres: 65,340 sq ft ÷ 10.7639 sq ft/m² = 6,070.29 m².
- 4. Convert to Hectares: 6,070.29 m² ÷ 10,000 = 0.6070 Hectares.
- 5. Convert to Bigha (UP standard pucca: 27,225 sq ft): 65,340 ÷ 27,225 = 2.4000 Bigha.
- 6. Convert to Biswa (1/20 Bigha = 1,361.25 sq ft): 65,340 ÷ 1,361.25 = 48.00 Biswa.
- 7. Convert to Guntha (1,089 sq ft): 65,340 ÷ 1,089 = 60.00 Guntha.
- 8. Convert to Cent (435.6 sq ft): 65,340 ÷ 435.6 = 150.00 Cent.
Result Summary: 1.5 Acres equals exactly 65,340 sq ft, 7,260 Gaj, 2.40 Bigha (UP), 60 Guntha, or 150 Cents.
Inputs and Units to Verify
Reliable results require verified input data and strict consistency of units. Review all measurements, dimensions, rate benchmarks, and underlying assumptions before relying on the calculated outputs.
- Parcel Value: Enter positive numerical area measurement.
- Source Unit: Select original unit as recorded in survey deeds or title documents.
- Target Unit: Choose desired output measurement (e.g. Acres, Gunthas, Sq Metres, Sq Ft).
- Regional Definition: Verify local state definitions for Bigha, Biswa, or Ground, as these vary by state.
Key Checks / Assumptions
- Confirm local district revenue definitions for Bigha and Biswa; while 27,225 sq ft is standard pucca Bigha in UP, kachha Bigha can be one-third of this value in rural pockets.
- Always cross-reference conversion results against the official Khatoni, 7/12 extract, Patta, or Jamabandi revenue record.
- Check boundary coordinates with an authorized Total Station or DGPS physical land survey rather than relying solely on paper conversions.
- When comparing urban residential plots quoted in 'Gaj', remember that 1 Gaj equals exactly 1 Square Yard (9 square feet).
- In Southern India (Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, Kerala), 1 Cent = 435.6 sq ft (1/100 of an acre), and 1 Ground = 2,400 sq ft.
- In Western India (Maharashtra, Gujarat), 1 Guntha = 1,089 sq ft (1/40 of an acre), and 40 Gunthas equal exactly 1 Acre.
Understanding the Result
Outputs exact equivalent land area across metric, imperial, and regional Indian revenue units without rounding distortions.
Practical Tips
- When converting property sale deeds, always preserve at least four decimal places when calculating hectares or acres to prevent substantial square-foot discrepancies on large parcels.
- For plot boundary calculations, remember that area conversions do not define shape; two plots of identical area (e.g. 1000 sq ft) can have radically different frontages and depths (e.g. 20×50 ft vs 25×40 ft).
- Confirm whether municipal development authorities require building plans submitted in metric units (sq m) even if land was originally purchased in Gaj or sq ft.
- Verify encumbrance certificates (EC) and ensure the area recorded in the parent deed matches the current revenue record before executing agreements.
Limitations
- Traditional units such as Bigha, Biswa, and Katha have regional variations across different Indian states and districts; this tool uses the standard UP/North Indian benchmark (27,225 sq ft per Bigha).
- Does not replace a physical land boundary survey by a licensed government surveyor or revenue department demarcation.
- Does not determine setback requirements, road widening deductions, or permissible Floor Space Index (FSI/FAR).
- Legal property registration must always adhere to the units and measurements recognized by the local state sub-registrar office.
Practical Workflow
- Review parcel area from registered title deeds, 7/12 extracts, or cadastral map surveys.
- Input numerical value and select current unit of measure.
- Select desired reporting unit for property transactions, approvals, or development proposals.
- Verify regional multipliers with local revenue department (Taluk / Patwari) norms.
- Document converted figures in formal project boundary sheets.
Frequently Asked Questions
How many square feet are in 1 Gaj?
1 Gaj is equivalent to 1 Square Yard, which equals exactly 9 Square Feet (3 feet × 3 feet = 9 sq ft). In many North Indian property markets, residential plots are commonly quoted in Gaj.
How many Gunthas make one Acre?
Exactly 40 Gunthas make one Acre. One Guntha equals 1,089 Square Feet (33 feet × 33 feet). Therefore, 40 Gunthas × 1,089 sq ft = 43,560 sq ft, which is exactly 1 Acre.
What is the difference between Bigha and Biswa?
Biswa is a fractional sub-unit of Bigha. In standard North Indian revenue measurement, 1 Bigha (pucca) contains exactly 20 Biswa. In Uttar Pradesh, 1 Bigha equals 27,225 sq ft, making 1 Biswa equal to 1,361.25 sq ft.
How many square feet are in 1 Cent of land?
1 Cent equals exactly 435.6 Square Feet, which represents 1/100th of an Acre (43,560 sq ft ÷ 100 = 435.6 sq ft). Cent is the predominant customary land measurement unit across Southern India (Tamil Nadu, Kerala, Andhra Pradesh, and Karnataka).
Important Professional-Use Note
Regional land units (such as Bigha, Katha, and Ground) have distinct statutory definitions across Indian states. For legal conveyance, registration, and boundary disputes, always refer to certified state revenue cadastral records.
