Katha to Square Feet — East India Guide

Katha is regional — start with your city

Katha evolved from Mughal and colonial revenue maps where each province fixed its own rectangle of Biswa or decimal fractions. Patna, Muzaffarpur, Bhagalpur, Siliguri, and Guwahati each have broker conventions that do not match without conversion. BhumiMeter binds Katha variants to state data files — select Bihar + Patna Katha in the converter for 1,361.25 sq ft, then cross-check the name on your deed.

Katha, Decimal, and Bigha in speech

Brokers may say "3 Katha 5 Decimal" — decimal is a fraction of an acre or local chain depending on state. Convert each term separately in our tool rather than adding numbers mentally. Bihar Bigha links to Katha through the state file; see Bigha chart for sq ft per Bigha. UP buyers near Bihar border: compare with UP Bigha (27,225 sq ft eastern).

West Bengal and Assam notes

• Kolkata and district Katha sizes differ — pick the correct variant in converter state dropdown.
• Assam listings may pair Katha with Bigha; verify on Dharitree/ Bhunaksha exports.
• Convert to sq ft before comparing with cent-based South India plots.
• NRI heirs often need sq m — use sq ft to sq m guide after Katha step.
