Square Yard (Gaj) to Katha
Convert square yard (gaj) to katha using the correct value for your state — square yard (gaj) is not the same size everywhere in India.
Also called gaj. 1 gaj = 9 sq ft. The most common way plots are quoted in North India.
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.
Handy in Bihar and Bengal, where a plot may be advertised in gaj but recorded in katha. A gaj is fixed at 9 sq ft, so the whole answer depends on the local katha.
