In many parts of India and South Asia, the word Jamin means land or plot. Whether it is farmland, residential land, or a commercial plot, knowing the exact area of your land is very important. Land area is needed for buying and selling property, planning construction, farming, legal documents, and government records.
Land plots are not always simple rectangles. Some are triangular, some are four-sided with uneven edges, and some have irregular shapes. On top of that, land area is often measured in regional units like Bigha, Katha, Decimal, Acre, and Guntha instead of only square meters or square feet.
Jamin Area Calculator (Land Measurement)
Calculate land area and convert to Acre, Hectare, Bigha, Katha & more.
What the Jamin Area Calculator Is
The Jamin Area Calculator is an online tool used to calculate the area of land based on its shape and dimensions. It supports multiple land shapes such as:
Rectangular or square plots
Triangular land
Four-sided (quadrilateral) plots using a diagonal
After calculating the area, the tool can also convert the result into regional land units like:
Acre
Bigha
Katha
Decimal
Dhur
Guntha
This makes it very useful for people who deal with land measurement in different regions of India.
How the Jamin Area Calculator Works
Inputs You Enter
Depending on the shape of your land, the calculator asks for:
Length and width for rectangular plots
Three side lengths for triangular land
Four sides and one diagonal for quadrilateral land
Your region or unit type for conversion
These measurements describe the exact shape and size of the land.
Calculation Process
The calculator follows these steps:
It identifies the land shape
It applies the correct area formula
It calculates the total land area
It converts the area into local units
Output You Get
You receive:
Total land area
Converted value in regional units
The results are shown clearly for easy understanding.
Key Formulas Used
Rectangle / Square Land
A = l \times wThis formula is used when the plot has straight and equal sides.
Triangle Land (Heron’s Formula)
s = \frac{a + b + c}{2} A = \sqrt{s(s - a)(s - b)(s - c)}This is used when the land has three uneven sides.
Quadrilateral Land (Using Diagonal)
The land is divided into two triangles:
A_{total} = A_1 + A_2Each triangle is calculated using Heron’s formula.
Step-by-Step Examples
Example 1: Rectangular Plot
Length = 40 m
Width = 20 m
If converted to acres:
800 \div 4046.86 = 0.198 \text{ acres}So, the land area is 0.198 acres.
Example 2: Triangular Land
Sides: a = 30 m, b = 40 m, c = 50 m
s = \frac{30 + 40 + 50}{2} = 60 A = \sqrt{60(60-30)(60-40)(60-50)} A = \sqrt{60 \times 30 \times 20 \times 10} A = 600 \text{ m}^2Example 3: Four-Sided Plot
If a quadrilateral plot has a diagonal, it is split into two triangles and each area is calculated separately, then added together for the total land area.
Regional Land Unit Conversion
Different Indian regions use different land units. The calculator converts square meters into:
Acre for official and real estate use
Bigha for northern states
Katha for Bihar, Assam, and West Bengal
Decimal for small land measurements
Guntha for Maharashtra and Gujarat
This saves people from manually remembering conversion values.
