The area of one Bigha varies significantly by state:
- • Uttar Pradesh: 27,000 sq ft
- • Bihar: 27,220 sq ft
- • Haryana: 27,225 sq ft
- • Punjab: 9,070 sq ft
- • West Bengal: 14,400 sq ft
- • Himachal Pradesh: 8,712 sq ft
Always specify the state when converting Bigha to avoid confusion.
Acre and Hectare are both standardized units but from different systems:
1 Acre (Imperial)
- • 43,560 square feet
- • 4,840 square yards
- • 0.4047 hectares
- • Commonly used in India
1 Hectare (Metric)
- • 10,000 square meters
- • 107,639 square feet
- • 2.471 acres
- • International standard
Guntha conversion is standardized across states that use this unit:
Standard Formula:
- • 1 Guntha = 1,089 sq ft
- • 40 Guntha = 1 Acre
- • 1 Acre = 43,560 sq ft
Quick Conversion: Divide Guntha by 40 to get Acres, or multiply by 0.025
Example: 100 Guntha = 100 ÷ 40 = 2.5 Acres
India's diverse land measurement systems developed due to several historical factors:
Historical Governance
Different kingdoms and regional rulers developed their own measurement standards
Agricultural Practices
Units evolved based on local farming methods, crop types, and land productivity
Cultural Influences
Language, traditions, and regional customs shaped measurement terminology
Colonial Impact
British administration attempted standardization but often adapted to local systems
The Katha system is primarily used in eastern and northern Indian states with significant variations:
| State | 1 Katha = | Bigha Relation | Usage |

| Bihar | 1,361 sq ft | 20 Katha = 1 Bigha | Agricultural land |
| Assam | 2,880 sq ft | 5 Katha = 1 Bigha | Tea gardens, paddy |
| Jharkhand | 1,361 sq ft | 20 Katha = 1 Bigha | Tribal land, mining |
The Cent system is a standardized unit primarily used in South Indian states:
Standard Cent System
- • 1 Cent = 435.6 sq ft (standardized)
- • 100 Cent = 1 Acre (always)
- • 1 Cent = 40.468 sq meters
States using Cent system:
- • Tamil Nadu: Universal usage, 1 Ground = 5.5 Cent
- • Kerala: Residential and commercial property
- • Karnataka: Alongside Guntha in some regions
- • Puducherry: Standard for all land transactions

Our calculators maintain high precision while providing practical results:
Precision Standards
- • Internal calculations: 10+ decimal places
- • Display precision: 2-4 decimal places
- • Rounding: Standard mathematical rules
- • Accuracy: ±0.01% for most conversions
Practical Considerations
- • Land measurements have inherent tolerances
- • Survey variations can exceed 1-2%
- • Traditional measurements are approximations
- • Results suitable for planning and estimates
Recommendation: For high-value transactions, professional surveying is recommended for absolute precision.
Cross-state conversions require using standardized units as intermediaries:
Best Practice Method
Always convert through Square Feet or Acres for accuracy
Example: Punjab Bigha to West Bengal Bigha
Step 1
1 Punjab Bigha = 9,070 sq ft
Step 2
9,070 sq ft ÷ 14,400 = 0.63 WB Bigha
Result
1 Punjab Bigha = 0.63 WB Bigha
Tool Tip: Use our individual state calculators to find the sq ft value, then convert using the target state's calculator.
