The Mathematical Formula: 1 Acre to Gunta
Under official Indian survey and revenue measurement standards, 1 standard Acre contains exactly 43,560 square feet.
A Gunta is defined as 121 square yards (33 feet by 33 feet, which equals 1,089 square feet). Dividing the total square footage of an Acre by one Gunta yields the exact standard ratio: 43,560 / 1,089 = exactly 40 Guntas.
- Exact ratio: 1 Acre = Exactly 40 Guntas
- 1 Gunta in square feet: Exactly 1,089 sq ft (33 ft x 33 ft)
- 1 Gunta in square yards: Exactly 121 sq yards
- 1 Gunta in square meters: Approximately 101.17 sq meters
- 1 Hectare to Gunta: 1 Hectare = 2.471 Acres = Approximately 98.84 Guntas
Regional Usage in State Land Records (7/12 & RTC)
The Gunta is the legal sub-unit recorded in agricultural land title records across western and southern India.
In Maharashtra's 7/12 (Saat-Bara) extract and Karnataka's RTC (Pahani) records, land parcels are formally designated in Hectare-Are-Gunta format (where 1 Are = 100 sq meters, closely approximating 1 Gunta).
- Maharashtra (7/12 Extract): Land holding areas recorded in Hectare-Are (1 Are = approx. 1 Gunta)
- Karnataka (Bhoomi RTC): Official land certificates specify Acre and Gunta divisions
- Telangana & Andhra Pradesh: Land survey records in Dharani specify Acre and Guntas
- Gujarat: Land revenue deeds recognize Gunta alongside Vigha divisions
Sub-Units: Anna, Cent, and Decimal Conversions
In traditional village surveys, a single Gunta is further subdivided into 16 Annas (where 1 Anna = 68.06 sq ft).
When cross-referencing land sizes across states with different measurement units, understanding the relationship between Guntas, Cents, and Bighas ensures accurate documentation.
- Gunta to Anna: 1 Gunta = 16 Annas (1 Anna = 68.06 square feet)
- Gunta to Cent: 1 Acre = 40 Guntas = 100 Cents (1 Gunta = 2.5 Cents = 1,089 sq ft)
- Gunta to Bigha: In Pucca Bigha states (27,225 sq ft), 1 Bigha = 25 Guntas
- Legal caution: Verify the official survey chain (Gunter's chain of 66 feet) on local cadastral maps
