How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Formula and method

With the 720 ft²-per-katha preset, 2 katha is 1,440 ft² or 133.7803776 m². With the 3,645 ft² preset, the same count describes a different area.

Area in square feet = katha count × selected square-feet-per-katha factor

Worked example

Enter these known values and leave the other values blank.

Area convention and explicit factor
Bangladesh preset — 720 ft²
Number of katha under that convention
2 katha
Equivalent area, initially square feet
1440 ft²
Equivalent area, initially square meters
133.78 m²

Assumptions and limitations

  • Katha is region-dependent. Match the displayed numerical factor to the convention used in the original measurement or record.
  • The Assam choice uses the Brahmaputra Valley convention of 2,880 ft². Assam’s Barak Valley uses 720 ft²; choose a 720 ft² preset for that arithmetic.
  • Several retained presets use whole-square-foot approximations, including 1,361 ft². Results are exact arithmetic for the selected factor, not proof that a rounded preset matches a specific parcel record.
  • Area and katha counts are nonnegative. One international square foot is exactly 0.09290304 m².

Common questions

Why is a regional selection necessary?

The same katha count can denote different areas under different local conventions. The selected square-foot factor determines this calculation.

Why show the factor in every option?

It lets you compare the preset with the source measurement directly instead of assuming a place name uniquely establishes the unit.

Bookify requires nonnegative quantities in this volume/mass, dose-unit or land-area conversion. The international acre is exactly 43560 square international feet; Bookify replaces the rounded captured area factor.
