The decimal is a traditional South Asian land measure equal to 1/100 of an acre (≈ 0.01 acre).
In more familiar units, 1 decimal = 48.4 square yards, 435.6 square feet or approximately 40.47 square meters.
The term "decimal" derives from the Latin decimus, meaning "tenth", reflecting its basis in the decimal subdivision of the acre.
Following metrication efforts in the mid-20th century in India and Bangladesh, the decimal was officially rendered obsolete, yet it persists informally in land transactions.
Today, decimals remain in active use among rural communities, especially in West Bengal and adjacent areas of Bangladesh, where small plots under one acre are commonplace.
Variations in practical size can occur by locality, but the standard conversion (1 decimal = 0.01 acre) is widely recognized.
Although superseded in official records by metric units (square meters and hectares), the decimal continues to appear in land deeds, brokerage listings, and local vernacular when describing sub-acre parcels.
