Why does a bigha differ from state to state?

Because it was never standardised nationally. A bigha is a customary unit and its size varies between and within states, so this tool asks which one you mean rather than assuming. A registered sale deed will state the area in square metres or square feet as well, and that figure is the authoritative one.

How many square feet are in a guntha?

1,089, which is 121 square yards. A guntha is one fortieth of an acre, and forty gunthas make an acre exactly.

Method and background

How this is calculated

The metric and imperial units are exact. The Indian units are not: bigha, kanal and marla were local measures long before they were standardised, and several still differ by district. The figures here are the commonly quoted ones for the named state, and a registry or a survey document is the authority for a specific plot.

result = value * factor_from / factor_to
