About this calculator
In-depth guide for the Land Area calculator — formulas, examples, and official sources for India.
Introduction
Land is often measured in acres, square feet, square meters, cents (South India), guntha (Karnataka/Maharashtra), or bigha (North India). This calculator converts between these units quickly.

Convert land area between acres, sq ft, sq m, hectare, cent, guntha, and bigha. Cent, guntha, and bigha do not have one national standard. This tool uses commonly used conversion values and is meant for quick estimates — verify with local land records for legal purposes.
Who should use this calculator
Anyone who needs a quick, accurate estimate for everyday calculations in India. Use this tool if you want a clear estimate before speaking with a bank, post office branch, or tax advisor.
