What Is Bangladesh Land Measurement?
Bangladesh uses a dual system: local traditional units for daily land talk, and survey decimal system for government records. The Ministry of Land (ভূমি মন্ত্রণালয়) and Department of Land Records & Survey (DLRS) maintain cadastral maps where land is often recorded in Decimal (শতাংশ / Shotangsho), while sellers may quote price per Bigha or Katha.
Understanding both systems prevents errors when buying agricultural land, homestead plots, or verifying mutation (নামজারি) and khatian (খতিয়ান) records.
