What Formulas Are Used in This Calculator?

The calculator uses a single base unit (Square Feet) and converts all other units to and from this base. The core “formulas” are the fixed equivalent values of each unit in Square Feet.

Base Unit: 1 Square Foot (Sq Ft)

Standard International Units (and their approximate Sq Ft equivalents):

  • 1 Square Meter (SqM) = 10.76391 Sq Ft
  • 1 Acre = 43,560 Sq Ft
  • 1 Hectare (Ha) = 107,639.1 Sq Ft (derived from 10,000 SqM * 10.76391 SqFt/SqM)

Traditional Indian Units (and their fixed Sq Ft equivalents):

  • 1 Decimal = 435.6 Sq Ft (Common in Eastern India – WB, Bihar, Jharkhand, Odisha)
  • 1 Guntha = 1089 Sq Ft (Common in Western/Southern India – MH, KA, GJ, MP, AP/TL)
  • 1 Ground = 2400 Sq Ft (Common in South India – Tamil Nadu, especially Chennai)
  • 1 Cent = 435.6 Sq Ft (Common in Southern India – KL, TN, KA, AP/TL, same as Decimal)
  • 1 Ankanam = 72 Sq Ft (Common in Andhra Pradesh/Telangana)

Regional Units (Bigha, Katha, Biswa) – Values depend on “Your Region” Selection:

The tool uses these approximate Square Feet values based on the selected region:

  • Bigha:

    • Uttar Pradesh (Pucca), Bihar (Common), Rajasthan, MP, Uttarakhand: 27,225 Sq Ft

    • Punjab, Haryana, Himachal Pradesh: 9,075 Sq Ft

    • West Bengal: 14,400 Sq Ft

    • Nepal (Nepali Bigha – Terai region): 72,900 Sq Ft

  • Katha:

    • Bihar (Common), Jharkhand (Common): 750 Sq Ft

    • Bihar (Specific – Lathi-based), Jharkhand (Specific): 1361.25 Sq Ft

    • West Bengal: 720 Sq Ft

    • Assam: 2880 Sq Ft

    • Odisha: 1600 Sq Ft

    • Nepal: 3645 Sq Ft

  • Biswa (1/20th of a Bigha in that region):

    • UP/Bihar/Rajasthan/MP/Uttarakhand (from Pucca Bigha): 1361.25 Sq Ft (27225 / 20)

    • Punjab/Haryana/HP (from Bigha): 453.75 Sq Ft (9075 / 20)

    • West Bengal (from Bigha): 720 Sq Ft (14400 / 20)

Important Disclaimer: While this tool uses the most commonly accepted values, traditional unit values (especially Bigha, Katha, Biswa) can still have slight variations based on very local customs, specific land records, and precise area definitions. Always confirm final and precise measurements with local authorities, a Patwari, or property experts before making any major decisions.

How Our Land Area Units & Conversions Tool Works:

This tool works by using a common base unit (Square Feet) for all conversions, and by allowing you to specify your region for variable units:

Input Your Value: Enter the numerical value of the land area you want to convert.

Select Input Unit: Choose the unit of your entered value from a comprehensive dropdown list (e.g., Sq Ft, Acre, Bigha, Katha, Decimal, etc.).

Choose Your Region (Crucial for Bigha, Katha, Biswa): This is the most important step for accuracy with traditional Indian units. If your input or desired output unit is Bigha, Katha, or Biswa, you must select the specific Indian state or region (e.g., Uttar Pradesh, West Bengal, Bihar, Punjab, Nepal) from a dropdown. This tells the calculator which specific Square Feet value to use for that unit.

Instant & Dynamic Conversion: As you input values or change units/regions, the tool instantly converts your entered area into all other supported units. A dynamic table or list will display these converted values in real-time.

Conversion Logic:
Internally, the tool first converts your input value into its equivalent in Square Feet (Sq Ft), which acts as the universal base. Then, it converts this Square Feet value into all other target units using their respective Sq Ft equivalents.

✅ Common Questions in Q&A Format

Q3: Is the conversion always exact?
A3: For standard units (Sq Ft, SqM, Acre, Hectare, Decimal, Guntha, Ground, Cent, Ankanam), the conversions are fixed. For regional units (Bigha, Katha, Biswa), the conversions are based on widely accepted approximate values and may vary locally.

Q4: What is the base unit used for all conversions?

Frequently Asked Questions

Historically, land measurement units evolved locally based on regional customs, agricultural practices, and different ruling systems, leading to a diverse set of units across the country.

“Pucca Bigha” (often 27,225 Sq Ft) is a larger, more standardized Bigha, while “Kaccha Bigha” is a smaller, less standardized version (often 1/3rd of a Pucca Bigha) found in some regions. Our tool primarily uses the common Pucca Bigha values where applicable.

It helps farmers and agricultural businesses convert plot sizes between different local and standard units, useful for planning, yield estimation, and subsidy applications.

Yes, based on the definition that 1 Cent = 435.6 Sq Ft and 1 Acre = 43,560 Sq Ft, 1 Acre is precisely equal to 100 Cents.

Biswa is typically 1/20th of a Bigha in a particular region. So, its value depends entirely on the Bigha value of that specific area.

Hectare is a metric unit (based on meters), used globally, and is larger (approx. 2.47 acres). Acre is an imperial unit (based on feet), used in a few countries like the US/UK, and is smaller.

Due to historical variations in traditional units, local land records, and potential minor discrepancies, a local verification ensures legal accuracy and avoids future disputes.
