About the Area & Land Converter
Property, farmland and flooring are all measured in different area units depending on where you are — square feet for a flat, acres or hectares for land, square metres on a plan. The AlarmDaddy Area & Land Converter switches between square kilometre, square metre, square centimetre, hectare, acre, square mile, square yard, square foot and square inch.
Crucially for Indian buyers and farmers, it also covers the traditional land units used across the country: **gaj** (square yard), **bigha**, **biswa**, **katha**, **guntha**, **cent**, **decimal (dismil)**, **ground**, **ankanam**, **kanal**, **marla** and **killa**. So you can convert bigha to square feet, gaj to square metres, or guntha to acre in one place.
Enter a value, choose units, and read the result plus the full table — handy when a listing quotes square feet but the seller talks in bigha or gaj. Everything runs in your browser.

The formula
Each unit is defined in square metres (1 acre = 4046.8564224 m², 1 gaj = 0.8361 m², 1 guntha = 101.17 m², 1 cent = 40.47 m²). The value is converted to square metres, then divided by the target unit. Note: bigha, biswa and katha are not standardised nationally — this tool uses widely-cited standard ("pucca") values, so always confirm the local definition for legal or purchase decisions.
