Convert length, area and Bangladeshi land units in one place — square feet to square metres, mm to inch, katha, bigha, decimal and more. Type a number and see every unit at once.
Land units follow the standard Bangladesh convention (1 katha = 720 sq ft, 20 katha = 1 bigha, 1 decimal = 435.6 sq ft). Local practice can vary slightly by district — confirm before using these figures on legal documents.
Anyone working with drawings, land papers or site measurements ends up converting units constantly. Architects work in millimetres, contractors think in feet, imported fittings come in inches, and land in Bangladesh is measured in katha, bigha and decimal. Mixing them up leads to expensive mistakes.
This converter keeps the common ones in a single place. Pick a category, type a value, choose the unit you have, and every equivalent updates instantly — no need to remember conversion factors.
Converting a value is easy. Converting an old drawing, a scanned plan or a laser scan into a clean, dimensioned CAD or BIM model is real engineering work — and it is something ClickBit Digital does. If you have drawings that need redrawing, scaling or modelling, get in touch.
One katha equals 720 square feet in the standard Bangladesh convention. Twenty katha make one bigha, which is 14,400 square feet.
Divide millimetres by 25.4. So 100 mm ÷ 25.4 = 3.94 inches. This tool does it automatically under the Length category.
