Katha to Bigha
Convert katha to bigha using the correct value for your state — katha is not the same size everywhere in India.
A traditional unit whose size changes from state to state — always check the local value. · 1 bigha = 20 biswa
ℹ️ Pukka bigha (≈27,000 sq ft) shown; 1 bigha = 20 biswa. Western UP and kaccha bigha are much smaller (~6,800–13,600 sq ft) — confirm locally.
Please verify: bigha, katha and biswa vary by region and even by district, and can differ between pukka and kaccha measures. These are common values for a quick estimate — always confirm against your official land records (patwari / revenue department) before any deal or registration.
In most of eastern India 20 katha make a bigha — but Assam uses 5. Pick the state to get it right, because getting this ratio wrong is a five-fold error on a land deal.
