How to Calculate Land Area in Bihar

Calculating land area is essential for property transactions, construction planning, and agricultural purposes. Follow these steps:

1. Measure Your Land

Use a measuring tape or professional surveying equipment to measure the length and width of your property. For irregular shapes, divide the land into regular shapes (rectangles, triangles) and calculate each separately.

2. Choose the Right Units

In Bihar, traditional units are commonly used in property documents:

  • Square Feet (Sq Ft): Most common for urban properties
  • Katha/Dhur: Traditional units used in rural areas and older records
  • Bigha: Used for larger agricultural lands
3. Understand Shape Variations

Different shapes require different calculation methods:

Shape Formula Example
Rectangle Length × Width 100 ft × 50 ft = 5,000 sq ft
Triangle (Base × Height) ÷ 2 (100 ft × 50 ft) ÷ 2 = 2,500 sq ft
Circle π × Radius² (π ≈ 3.1416) 3.1416 × 50 ft × 50 ft ≈ 7,854 sq ft
