শতক, কাঠা, বিঘা ও একর (Shotok, Katha, Bigha, Acre)
| Unit | Equals | Square feet | শতক |
|---|---|---|---|
| ১ ছটাক (Chatak) | — | 45 | 0.103 |
| ১ কাঠা (Katha) | 16 Chatak | 720 | 1.65 |
| ১ শতক (Shotok / Decimal) | 1/100 Acre | 435.6 | 1 |
| ১ বিঘা (Bigha) | 20 Katha (80 Hat × 80 Hat) | 14,400 | 33.06 |
| ১ একর (Acre) | 100 Shotok = 3.025 Bigha | 43,560 | 100 |

কানি–গণ্ডা system (৮ হাত নল)
| Unit | Equals | Square feet |
|---|---|---|
| ১ তিল (Til) | — | 3.6 |
| ১ ক্রান্তি (Kranti) | 20 Til | 72 |
| ১ কড়া (Kora) | 3 Kranti | 216 |
| ১ গণ্ডা (Gonda) | 4 Kora | 864 |
| ১ কানি (Kani) | 20 Gonda (about 40 Shotok) | 17,280 |
⚠ It varies by region: কানি and গণ্ডা are not the same size in every district. In the Chattogram–Noakhali area the ৮ হাত নল reckoning is usual (1 কানি = 20 গণ্ডা = 17,280 square feet), while elsewhere 1 গণ্ডা is treated as roughly 1 শতক, making 1 কানি about 40 শতক. Pick the system that matches your own district above, and for any transaction rely on the figure written on the deed.

How many শতক is 1 বিঘা?
In Bangladesh 1 বিঘা = 20 কাঠা = 14,400 square feet ≈ 33 শতক (33.06 to be exact). So 3 বিঘা comes to roughly 1 একর.
