Land Area Converter

Bangladeshi land units in one place

Land in Bangladesh is bought in katha, recorded in shotangsho, inherited in bigha and surveyed in acres — and a deed often uses two of them at once. This converter puts a single plot into every unit at the same time, so you can read a document in whichever unit you think in.

The conversions used here

• 1 katha = 720 sq ft · 1 bigha = 20 katha = 14,400 sq ft
• 1 shotangsho (decimal, shotok) = 435.6 sq ft · 1 bigha = 33 shotangsho
• 1 acre = 100 shotangsho = 43,560 sq ft = 3.025 bigha
• 1 kani = 40 shotangsho = 17,424 sq ft · 1 gonda = 2 shotangsho = 871.2 sq ft
• 1 hectare = 107,639 sq ft = 2.47 acres · 1 square metre = 10.764 sq ft

Worked example

A 5 katha plot is 3,600 square feet, which is 0.25 bigha, 8.264 shotangsho, 334.45 square metres and 0.083 acres. At 40 lakh per katha, the plot is worth 2 crore.

How to use the land converter

1. Enter the amount and pick the unit it is written in.
2. Read the table — the same plot appears in every common unit at once.
3. Add a price per katha if you want the value of the plot alongside the area.

Where the units differ

• Kani and gonda vary by region. The common Chittagong and Noakhali kani of 40 shotangsho is used here; in some districts a kani is 120 shotangsho.
• A katha is 720 sq ft across most of Bangladesh, but in parts of India it is 1,361 sq ft or 1,620 sq ft. Do not mix the two when reading an Indian document.
• For anything legal — a deed, a mutation, a loan — use the figures on the official record and confirm with the AC Land office. This tool is for working things out, not for proving them.
