What is Shotok?
Shotok, also known as Decimal, is one of the most common land units in Bangladesh. One Shotok equals exactly 1/100 of an acre — about 435.6 square feet or 40.47 square meters. Property in rural and semi-urban Bangladesh is frequently priced and recorded in Shotok, making it essential for buyers, sellers, and CS/RS record checks.
What is Katha?
Katha is heavily used in both Bangladesh and West Bengal, especially for residential plots. In the standard system, one Katha equals 720 square feet, and twenty Katha make one Bigha. Because urban plots are often described in Katha, converting Katha to square feet and square meters is one of the most frequent needs.
What is Bigha?
Bigha is a larger traditional unit. In the standardized Bangladesh and West Bengal system, one Bigha equals 20 Katha, or 14,400 square feet — roughly 33.06 Shotok, or about one-third of an acre. Note that Bigha size historically varied by region, so always confirm the local standard for legal transactions.
What is an Acre?
The acre is an internationally recognized unit equal to 43,560 square feet or about 4,046.86 square meters. Because one acre equals exactly 100 Shotok, it acts as a natural bridge between traditional South-Asian units and the metric system used in official surveys.
Land Measurement in Bangladesh
Bangladesh commonly uses Shotok, Katha, Bigha, and Acre alongside metric units. A typical chain is: 1 Acre = 100 Shotok, 1 Bigha = 20 Katha = 14,400 sq ft, and 1 Katha = 720 sq ft. Our converter locks these relationships to a precise square-meter base so every result stays consistent.
Land Measurement in West Bengal
In West Bengal (পশ্চিমবঙ্গ), official land records (CS, RS, and LR Khatian/Porcha) heavily use Shotok (Decimal/শতক) alongside Katha (কাঠা), Bigha (বিঘা), Chatak (ছটাক), Dhur (ধুর), and Ganda (গণ্ডা). One Shotok equals 1/100 of an acre (435.6 sq ft). In West Bengal's standard land revenue chain: 1 Bigha = 20 Katha = 33.06 Shotok = 14,400 sq ft, 1 Katha = 16 Chatak = 720 sq ft, 1 Chatak = 4 Ganda = 45 sq ft, and 1 Katha = 20 Dhur (36 sq ft per Dhur). Micro-shares in older deeds are recorded in Kranti (3.75 sq ft) and Til (0.1875 sq ft).
