Where you’ll use it
Square feet is the language of plot sales, building plans and municipal approvals, while the bigha survives in village records and in how families talk about land. Converting is common when agricultural land near a town is split into house plots, when a developer quotes a price per square foot for land the seller knows in bigha, or when a builder needs the plot area for a map approval. In those cases a mistake of one variant changes the area by tens of thousands of square feet.
Tip: For a plot you can walk, measure it directly instead of trusting a bigha conversion. The sides of a 14,400 sq ft bigha are about 120 ft if square, a 27,225 sq ft bigha about 165 ft, which is a quick sanity check on the ground.
