🌾 Regional & International Land Measurement FAQs

Why does 1 Bigha vary in square feet across different states in India?

Historically, land measurement in India was codified under diverse local rulers, British colonial settlement systems (such as the Permanent Settlement in Bengal/Bihar and Ryotwari/Mahalwari in North India), and post-independence state revenue codes. For instance, the UP Revenue Code sets 1 Pucca Bigha at 27,225 sq ft (55 × 55 yards), while Uttarakhand's Garhwal-Kumaon hill settlement historically codified 1 Bigha as 6,804 sq ft (756 sq yards). Using the wrong state formula during property registry can lead to catastrophic legal errors.

How much is 1 Bigha in Uttar Pradesh, Dehradun, Bihar, and Punjab?

1 Bigha varies by state: Uttar Pradesh (Pucca): 27,225 sq ft (3,025 Gaj); Uttar Pradesh (Kaccha): 9,075 sq ft; Uttarakhand (Dehradun): 6,804 sq ft (756 Gaj); Bihar: 27,220 sq ft (20 Kattha); Punjab & Haryana: 9,075 sq ft (or 4 Kanals); Rajasthan (Pucca): 27,225 sq ft; Assam & West Bengal: 14,400 sq ft; Himachal Pradesh: 8,712 sq ft.

What is the difference between Pucca Bigha and Kaccha Bigha?

A Pucca Bigha is the standard, legally recognized unit in state revenue department land records (e.g. 27,225 sq ft in UP). A Kaccha Bigha is a traditional rural subdivisional measure, typically one-third (9,075 sq ft in UP) or slightly less, commonly used by local village elders before formal survey demarcation.

How much is 1 Bigha in Dehradun, Uttarakhand, and why is it smaller than UP?

In Dehradun and throughout Uttarakhand, 1 Bigha equals exactly 6,804 square feet (756 Gaj or square yards, or ~632.11 square meters). It is approximately 3.15 traditional Pahari Nalis. British settlement officers (Traill & Beckett) established this smaller measure to match the physical yield and terrace-plowing capacity of mountain terrain.

What is a Nali in Uttarakhand, and how many square feet is 1 Nali?

1 Nali equals exactly 2,160 square feet (240 Gaj or ~200.67 square meters). 1 Nali is subdivided into 16 Mutthi (1 Mutthi = 135 sq ft). In Uttarakhand land registry, 1 Bigha contains approximately 3.15 Nalis.

What is 1 Guntha in Maharashtra, Gujarat, and Karnataka?

1 Guntha equals 1,089 square feet (measuring 33 ft × 33 ft, or 121 Gaj / 101.17 square meters). In Maharashtra, 40 Gunthas equal exactly 1 Acre. Official 7/12 extract (Saat Baara) land records express areas in Hectares, Are (1 Are = 1 Guntha), and Square Meters.

What are Ground and Cent in Tamil Nadu, Kerala, and South India?

1 Cent equals 435.6 square feet (1/100th of an Acre or 40.47 m²). In urban Tamil Nadu (especially Chennai and Coimbatore), plots are quoted in "Ground" (1 Ground = 2,400 sq ft or 266.67 Gaj). Therefore, 1 Ground equals approximately 5.51 Cents.

How many Bighas make 1 Acre and 1 Hectare across different Indian states?

How do I convert agricultural land measurements into Square Meters (m²) for registry?

To convert square feet into square meters, multiply by 0.092903 (or divide square feet by 10.7639). Modern computerized land registries (UP Bhulekh, Bihar Bhumi, Mahabhulekh, Kaveri) require stating total plot area in square meters alongside traditional local units.

Which official revenue documents verify land area in India?

Always verify: Khasra (plot/survey number and soil classification), Khatauni (record of rights and verified landholding shares), Jamabandi (ownership record in Punjab/Haryana), 7/12 Extract (Saat Baara in Maharashtra/Gujarat), and Patta/Chitta (Tamil Nadu/AP). Ensure the ground survey (Naksha) matches the sale deed dimensions.

🏗️ Building, Civil Engineering & Construction Material FAQs

How many bags of cement are needed for 1,000 square feet of roof slab casting?

For a 1,000 sq ft roof slab with a standard 5-inch thickness (0.416 ft), total concrete volume is 416 cubic feet (~11.8 cubic meters). Using standard M20 grade RCC (1:1.5:3 mix ratio), approximately 90 to 95 bags of cement (50 kg each) are required, along with ~170 cubic feet of sand and ~340 cubic feet of coarse aggregate gravel.

How do you calculate steel (TMT rebar) weight using bar diameter?

Use the standard Indian Standard (IS 1786) formula: Weight (kg/meter) = D² / 162, where D is the diameter of the TMT bar in millimeters. For example: 8mm = 8² / 162 = 0.395 kg/m; 10mm = 10² / 162 = 0.617 kg/m; 12mm = 12² / 162 = 0.888 kg/m; 16mm = 16² / 162 = 1.578 kg/m.

How many kilograms of steel are required per square foot of house construction?

By thumb rule in India, a standard G+1 or G+2 residential house requires approximately 3.5 kg to 4.5 kg of steel per square foot of built-up area. For a 1,000 sq ft house, you will need approximately 3.5 to 4.5 metric tons (3,500 kg to 4,500 kg) of TMT steel rebar.
