Jamin Area Calculator (Land Measurement)
Calculate Area in Acre, Hectare, Bigha, Katha & More
In the vast and diverse landscape of India, “Jamin” (Land) is rarely measured in simple Square Feet. Instead, we use a rich tapestry of traditional units that change every few hundred kilometers. From the Bigha of the North to the Guntha of the West and the Ground of the South, navigating these regional standards can be confusing for buyers, sellers, and farmers.
The Jamin Area Calculator is your digital Patwari (Guide). It instantly converts standard measurements into your specific local unit, ensuring that whether you are in Bihar, Maharashtra, or Tamil Nadu, you know exactly how much land you own.
Key Regional Units
North & East India (Bihar, UP, Bengal)
- Bigha: The king of units. But beware—it is not standard! A “Pucca Bigha” in UP is 27,225 sq ft, while in Bihar it varies by village. Always specify “Kachha” or “Pucca”.
- Katha (or Cottha): A sub-unit. usually 20 Kathas = 1 Bigha.
- Dhur: A smaller unit. 20 Dhurs = 1 Katha.
West India (Gujarat, Maharashtra)
- Guntha: The standard for plotting agricultural land. One Guntha is approx 1,089 sq ft (33 ft x 33 ft).
- Acre: Widely used for larger tracts. 40 Gunthas = 1 Acre.
South India (Tamil Nadu, Kerala)
- Ground: Common in Chennai real estate. One Ground = 2,400 sq ft.
- Cent: 1/100th of an Acre (435.6 sq ft). Used extensively in Kerala.
- Ankanam: Used in parts of Andhra/Telangana (usually 72 sq ft).
How to Use This Calculator
Select your state and unit to get started:
1. Select Your State/Region
Because a “Bigha” in Bihar is different from a “Bigha” in Rajasthan, selecting your region sets the correct conversion factor.
2. Input Measurement
Enter the Total Area in Square Feet, Meters, or Yards. OR, enter the side lengths of the plot if you haven’t calculated the area yet.
3. The Laggi Size (Bihar Specific)
In rural Bihar, the area of a Dhur is determined by the “Laggi” (measuring pole) length, measured in “Haath” (cubits). Common sizes are 5.5, 6, or 6.5 Haath. Adjusting this slider changes the calculation of Dhur, Katha, and Bigha.
Why This Matters
Agricultural Planning
Government subsidies for fertilizer and seeds are often allotted per Hectare or Acre. Farmers thinking in Bighas need accurate conversions to claim their full benefits.
Real Estate Registry
Property disputes often arise from unit confusion. A seller might promise “1 Bigha” meaning a small Kachha Bigha, while the buyer expects a large Pucca Bigha. Converting everything to Square Feet provides a neutral, legal standard for the sale deed.
Construction
Architects design in Square Feet or Meters. If you tell a contractor your plot is “2 Kathas,” they cannot estimate cement bags until it is converted to a standard engineering unit.
Frequently Asked Questions (FAQ)
What is a “Decimal”?
Decimal is a standard unit used across East India (West Bengal, Odisha, Jharkhand). It is exactly 1/100th of an Acre or 435.6 sq ft. It is popular because it doesn’t fluctuate like the Bigha.
How do I measure an irregular field?
Most fields are not perfect rectangles. The “Heron’s Formula” method is best: divide the field into triangles, measure all three sides of each triangle, and the calculator sums them up.
Is a Hectare bigger than an Acre?
Yes. One Hectare is 10,000 square meters, which is approximately 2.47 Acres. Hectare is the standard metric unit used in official government land records (Khata/Khesra).
Final Words
Land is the most valuable asset in India. Do not let “Laggi” confusion or regional variations undervalue your property. Use the Jamin Area Calculator to speak the language of land with confidence and precision.
