Real estate listings around the world use wildly different units. The same plot of land might be described as 5 katha in Dhaka, 30 decimal in rural Bengal, 8,300 square feet in city listings, or 0.19 acre in an international ad. This calculator converts between all the common ones so you can compare like with like.
The unit definitions matter: a "katha" in Bangladesh (720 sq ft) is different from a "katha" in some parts of India, where regional variations push it to 1,000+ sq ft. Always confirm the local definition when buying property — the calculator uses the most common Bangladesh values.
For metric users buying or selling in South Asia, the most useful conversion is usually square metres to katha or decimal. For agricultural land, acres and hectares dominate; for urban plots, square feet and square metres are the everyday units.
Historical reasons. Many traditional units were defined by what one person could plough in a day, or by local royal decree. Standardisation never reached land measurement the way it reached weights and metric volumes.
Almost, but check locally for very rural deals. The values used here are the most common modern Bangladesh definitions.
Mathematically exact for the unit definitions used. The risk is in the definitions themselves varying regionally — always confirm with a local lawyer or land surveyor before a transaction.
