How many shotangsho in one katha?

Oh honey, a katha is a unit of area measurement in South Asia, typically used in Bangladesh and Nepal. It's equivalent to 20 lecha or 338.63 square meters. As for shotangsho, I have no clue what that is. Maybe you meant "chotangsho," which is a unit of measurement in Bangladesh equal to 1/100th of a katha. So, there you have it, one chotangsho in one katha.
