How It Works
This converter turns any Bangladeshi land measurement into every other unit at once, using the Ministry of Land standard factors with square feet as the canonical base. It also surfaces the district-by-district variation that trips people up with kani and bigha.
- 1Enter an amount and pick a unitType a value and choose the source unit - katha, bigha, shotok (decimal), kani, gonda, ojutangsho, square foot, square metre or acre. Quick-amount chips (0.5, 1, 5, 10, 20) speed up common lookups.
- 2Read the live result across all unitsThe headline card shows shotok, square feet and square metres immediately, and the grid below lists every unit. Conversions recompute instantly as you type - no submit button.
- 3Choose a regional conventionBecause kani and bigha differ by district, pick a preset (Ministry standard, Noakhali/Chittagong 120-decimal kani, Sylhet, or a 60-decimal bigha). Affected units are flagged with an asterisk so you never silently get the wrong value.
- 4Copy or shareTap any tile to copy its value, switch between Western (123) and Bengali (১২৩) digits, or use Copy all to grab a full labelled summary. Expand the reference table for the exact square-feet and decimal factors.
Every calculation runs entirely in your browser. Nothing you enter is uploaded, logged, or stored on any server.
