By the common standard 1 katha = 720 square feet, so 1 katha ≈ 1.653 decimals. Conversely, 1 decimal ≈ 0.605 katha.

1 bigha = 20 katha = 14,400 square feet, i.e. about 33.06 decimals. However, the size of a bigha can vary by region.

No. The most common standard in Bangladesh is 720 square feet per katha and 20 katha per bigha, which this converter also uses. Local custom differs in some regions — check the local value when reconciling figures with a deed.

Yes, they are the same. Deeds and khatians often say 'decimal', while people say 'shotok' or 'shotangsho' — all three mean the same unit.
