West Bengal Land Area Converter — Katha, Bigha
West Bengal's BLRO (Block Land Reforms Office) records measure land in Bigha and Katha, with 20 Katha making one Bigha. These are the numbers that appear on Bengal's Record of Rights (RoR) and are what banks and registrars check against when you're buying land in Kolkata's suburbs or rural Bengal.
Guntha, Bigha, and Katha values vary by state. Using West Bengal standard — 1 Bigha = 14,400 sq ft, 1 Katha = 720 sq ft, 1 Guntha = 1,089 sq ft. Source: West Bengal BLRO (Block Land Reforms Office) land records.

Why West Bengal's Units Differ
Bengal's Bigha (≈14,400 sq ft, about 0.33 acre) is roughly half the size of Uttar Pradesh's or Bihar's Pucca Bigha (≈27,225 sq ft). This is not a rounding difference — it's because each state fixed its own local Bigha independently, based on regional agricultural plot conventions, and neither the British land-settlement system nor independent India ever standardized the unit nationally. The same asymmetry carries down to Katha: Bengal's Katha is 720 sq ft, while Bihar's Katha is nearly double at about 1,361 sq ft. If you're comparing a Bengal Bigha figure against a Bihar or UP one, they are not interchangeable — always check which state's standard a document is using.

Bigha
1 Bigha (West Bengal) = 14,400 sq ft = 1,337.8 sq m ≈ 0.33 acre.
