The Bigha-to-Acre Conversion Trap in Punjab Agricultural Land Banking
When acquiring agricultural or industrial land in Punjab, converting bighas to acres depends on the applicable revenue system. Applying Mohali's 2 bigha/acre factor to a Rajpura listing (where 4.8 bigha = 1 acre) results in a severe overestimation of acreage.
Regional Comparison of Bigha-to-Acre Ratios
1. Mohali/Kharar (System A): 2 bigha = 1 acre. 2. Rajpura/Patiala (System B): 4.8 bigha = 1 acre. 3. Ludhiana (System F): 1.6 bigha = 1 acre. 4. Majha (System D): 4.356 bigha = 1 acre.
