The Ultimate Guide to Indian Land Measurement Units
In the diverse landscape of Indian real estate, land measurement units change as frequently as the dialects. While the metric system (Square Meters, Hectares) is the official standard, regional units like Dismil, Katha, Bigha, and Ground dominate local property transactions. Toolvala.in's Indian Land Unit Converter is designed to bridge this gap, offering a unified platform to convert between these varied units instantly.
This guide explores the definitions, conversion formulas, and the regional significance of these units, helping you navigate property deals with confidence.
Understanding the Conversion Process
Converting land units involves a two-step mathematical process to ensure accuracy across all unit types. Here is a visual representation of how our calculator works:
(e.g., 1000 Sq Ft)
(Square Feet)
(e.g., Dismil)
1. Square Foot (Sq Ft)
The Square Foot is the most universally understood unit in Indian real estate, especially for residential apartments and commercial spaces. It is the area of a square with sides of 1 foot.
- Relation to Acre: 1 Acre = 43,560 sq ft
- Usage: Pan-India (Urban areas)
2. Dismil (Decimal)
The Dismil (or Decimal) is a legacy unit from the British era, representing 1/100th of an acre. It is the standard unit for agricultural land and plots in Eastern India.
Primary Usage: Bihar, Jharkhand, West Bengal, Odisha.
3. Katha (Cottah)
The Katha is a unit that varies significantly by region. In Patna, a Katha might be 1361 sq ft, while in rural Bihar, it could be 720 sq ft. Our calculator uses the "Standard Katha" widely accepted in legal documents.
- Standard Conversion: 1 Katha ≈ 1361.25 Sq Ft
- In Dismil: 1 Katha ≈ 3.125 Dismil
4. Bigha
The Bigha is a large unit used for agricultural land across North India. Like Katha, its size fluctuates.
- Standard Relation: 1 Bigha = 20 Katha
- Conversion: 1 Bigha ≈ 27,225 Sq Ft
5. Ground
Exclusively used in Tamil Nadu, particularly Chennai, for residential plots.
6. Guntha
Common in Maharashtra, Karnataka, and Andhra Pradesh.
- Conversion: 1 Guntha = 1,089 Sq Ft
- Relation: 40 Gunthas = 1 Acre
Conversion Cheat Sheet
Here is a quick reference table for common conversions based on the Standard Square Foot.
| Unit | Equivalent in Sq Ft | Equivalent in Dismil |
|---|---|---|
| 1 Dismil | 435.6 | 1 |
| 1 Cent | 435.6 | 1 |
| 1 Guntha | 1,089 | 2.5 |
| 1 Katha (Std) | 1,361.25 | 3.125 |
| 1 Ground | 2,400 | 5.51 |
| 1 Acre | 43,560 | 100 |
| 1 Hectare | 107,639 | 247.1 |
Why Precision Matters: The 1000 Sq Ft Dilemma
When converting 1000 sq ft to Dismil, you might see different results depending on rounding:
- Precise Calculation: 1000 / 435.6 = 2.295684...
- Rounded Calculation: Often rounded to 2.30 for simplicity.
Our tool allows you to choose the precision (2, 4, or 6 decimal places) to ensure you get the exact figure needed for legal documentation or the rounded figure for general estimation.
Tips for Accurate Land Measurement
- Verify the Unit: Always check if the "Katha" mentioned in a deed is the standard 1361 sq ft or a local variation (e.g., 720 sq ft).
- Use a Surveyor: For irregular plots, professional surveyors (Amins) use chains to measure the exact area.
- Cross-Check: Use this tool to convert the deed's values into Square Feet to visualize the actual size of the plot.
