About this calculator
Land in India is measured in bigha, guntha, cent, marla and acre, and plans and listings use square feet and square metres. The Area Converter turns any of these into all the others at once.
Standard units are exact: 1 acre is 43,560 square feet and 4,046.86 square metres, 1 hectare is 10,000 square metres, 1 guntha is 1,089 square feet and 1 cent is 435.6 square feet. Local units such as the bigha and marla vary by state, so confirm with your land record before you trade.
