Land measurement units in Bihar
In Bihar, land and plots are commonly measured in decimals, acres, as well as local units such as bigha, katha (kattha), dhur. The fixed units are converted below. Local units have no single value, so this page does not give one; it says how to get the real area instead.
Fixed units used in Bihar
Fixed definitions, the same everywhere in India.
Local units: bigha, katha (kattha), dhur
Their size differs by state and often by district or village.
A bigha in one part of Bihar is not the same size as in another, so any single figure would be wrong somewhere. Treat it as a label, not a measurement:
- Take the area in square feet or square metres from the land record (the jamabandi register), or ask the local revenue office for the value used in that village.
- Compare plots per square foot, not per bigha.
- Convert the recorded area with the area unit converter.
