Survey numbers, sale deeds and online records (Bhulekh, Dharani, Bhoomi, Meebhoomi, Banglarbhumi) rarely print the same unit a seller quotes. Convert everything to square feet or square metres before comparing offers: price per sq ft is the only fair way to compare a plot quoted in katha with one quoted in square feet. For rectangular plots, multiply length by breadth in feet to get square feet, then convert. Always get the final measurement from a licensed surveyor and match it to the registered document before paying.
