Understanding the Bigha to Acre Conversion Formula

Unlike the standardized international acre, which is strictly standardized at exactly 43,560 square feet (4,840 square yards or approximately 4,046.86 square meters), the Bigha is a traditional land measurement whose physical size depends on the state and local revenue code where the land is situated.

To convert Bighas to Acres accurately, you must always divide the total square footage of the regional Bigha by 43,560:

General Formula:
Acres = (Number of Bighas × Square Feet in Regional Bigha) ÷ 43,560

State-Wise Conversion Multipliers:

Uttar Pradesh, Rajasthan, and Madhya Pradesh (Pucca Bigha):
1 Pucca Bigha = 27,225 sq ft (3,025 Gaj).
Conversion: 27,225 ÷ 43,560 = 0.6250 Acre (exactly 5/8 Acre).
Inverse: 1 Acre = 1.6000 Pucca Bighas.
Haryana & Punjab (Traditional Bigha):
1 Traditional Bigha = 21,780 sq ft (2,420 Gaj = 4 Kanals).
Conversion: 21,780 ÷ 43,560 = 0.5000 Acre (exactly 1/2 Acre).
Inverse: 1 Acre (or Killa) = 2.0000 Bighas.
West Bengal & Assam (Standard Bigha):
1 Bigha = 14,400 sq ft (1,600 Gaj = 20 Katha).
Conversion: 14,400 ÷ 43,560 = 0.330578 Acre (approx 33.06 Decimals).
Inverse: 1 Acre = 3.0250 Bighas.
Gujarat (Vigha / Bigha):
1 Vigha = 17,424 sq ft (16 Gunthas = 1,936 Gaj).
Conversion: 17,424 ÷ 43,560 = 0.4000 Acre (exactly 2/5 Acre).
Inverse: 1 Acre = 2.5000 Vighas.
Bihar:
1 Bigha = 27,220 sq ft (20 Katha = 400 Dhur).
Conversion: 27,220 ÷ 43,560 = 0.624885 Acre (approx 0.625 Acre).
Inverse: 1 Acre = 1.6003 Bighas.
Himachal Pradesh:
1 Bigha = 8,712 sq ft (4 Kanals = 20 Biswa).
Conversion: 8,712 ÷ 43,560 = 0.2000 Acre (exactly 1/5 Acre).
Inverse: 1 Acre = 5.0000 Bighas.

Worked Real-World Examples

Example 1: Farmland in Meerut (Uttar Pradesh)

A farmer inherits 12 Pucca Bighas in Meerut district and needs to know the area in statutory Acres for bank loan documentation.

Total Sq Ft = 12 × 27,225 sq ft = 326,700 sq ft
Acres = 326,700 ÷ 43,560 = 7.5000 Acres

Result: 12 UP Pucca Bighas equals exactly 7.50 Acres.

Example 2: Agricultural Sale in Karnal (Haryana)

A buyer agrees to purchase 6 Bighas in Karnal. In Haryana, 1 Bigha equals 4 Kanals (21,780 sq ft).

Total Sq Ft = 6 × 21,780 sq ft = 130,680 sq ft
Acres = 130,680 ÷ 43,560 = 3.0000 Acres (3 Killas)

Result: 6 Haryana Bighas equals exactly 3.0 Acres (or 3 Killas).

Example 3: Tea Plantation Parcel in Jalpaiguri (West Bengal)

A tea garden boundary records an expansion parcel of 30 Bengal Bighas.

Total Sq Ft = 30 × 14,400 sq ft = 432,000 sq ft
Acres = 432,000 ÷ 43,560 = 9.9174 Acres (approx 992 Decimals)

Result: 30 Bengal Bighas equals approximately 9.92 Acres.

Example 4: Agricultural Holding in Anand (Gujarat)

An agricultural plot in central Gujarat measures 15 Vighas (16 Gunthas each).

Total Sq Ft = 15 × 17,424 sq ft = 261,360 sq ft
Acres = 261,360 ÷ 43,560 = 6.0000 Acres

Result: 15 Gujarat Vighas equals exactly 6.00 Acres.

Frequently Asked Questions

In Uttar Pradesh, 1 standard Pucca Bigha equals exactly 0.625 Acre (5/8 of an acre). This is calculated as 27,225 square feet divided by 43,560 square feet per acre. Conversely, 1 Acre equals 1.6 Pucca Bighas.

In Haryana and Punjab, 1 traditional Bigha equals exactly 0.500 Acre (half an acre or 4 Kanals), which equals 21,780 square feet. A standard agricultural parcel of 1 Acre (or Killa) contains exactly 2 Bighas.

In West Bengal, under the Bengal Tenancy Act, 1 Bigha is standardized at 14,400 square feet (1,600 Gaj), which equals approximately 0.330578 Acre (or 33.06 Decimals). Exactly 3.025 Bengal Bighas make 1 Acre.

A Pucca Bigha is a commonly referenced Uttar Pradesh land-area convention (27,225 sq ft = 3,025 Gaj); verify the definition used in the specific land record. Kaccha Bigha is an informal rural unit customarily equal to one-third of a Pucca Bigha (approx 9,075 sq ft or 1,008.33 Gaj), used colloquially by farmers in Western UP and eastern Rajasthan.

In Gujarat, 1 Vigha (or Bigha) equals 17,424 square feet (16 Gunthas), which translates to exactly 0.400 Acre. Therefore, 2.5 Gujarat Vighas equal exactly 1 Acre.

Historical land revenue assessments prior to Indian independence utilized local measuring ropes and chains (Jaribs) that varied between princely states and British presidencies. When state revenue codes were enacted post-1947, each state codified its prevailing local village cadastral maps (Shajra), preserving regional variation.

This calculator provides standard revenue equivalents, but official deed registration, mutation, and boundary surveys require consulting the official Khatauni or Khasra document issued by the local tehsil office or sub-registrar.
