Why Bigha varies by state
Understand why Bigha needs state, locality and record context before it is converted to a standard area unit.
The name is regional
Bigha developed through different local measurement and settlement systems, so the same name can represent different areas.
A state can still have exceptions
Some sources document more than one convention within a state. District, locality and the record itself can therefore matter.
Use a traceable factor
Choose a sourced factor only when it matches the location and record context, or enter a verified local factor and keep it visible.
Examples from the sourced dataset
GharGanit records 14,400 sq ft for the documented Assam Bigha context and 27,225 sq ft for the documented Rajasthan Bigha context. The difference is not a rounding error: the same regional name belongs to different local systems. Each figure therefore travels with its state, status, source and exception note.
| Context | Dataset factor | How to use it |
|---|---|---|
| Assam | 14,400 sq ft | Only with Assam source context |
| Rajasthan | 27,225 sq ft | Only with Rajasthan source context |
The state name may still be insufficient
A source can document district, settlement or historical exceptions within one state. Check whether the parcel’s record uses the same convention as the factor. A state dropdown is a discovery aid, not proof that one factor is legally universal across every locality.
How GharGanit treats uncertainty
Documented factors are tied to the recorded source context. Customary and approximate factors are labelled ‘verify locally’. Conflicting values are not averaged, and a number is withheld when the available evidence cannot support a responsible factor. Users can enter a custom local factor only after obtaining relevant evidence.
Verify before conversion
Read the registered deed, survey map and current official record. Record district, village and plot or survey identifiers, then confirm the unit and factor with the relevant authority or an authorised survey professional when needed. Convert to square feet or acre only after that location-sensitive step is resolved.
What the conversion cannot establish
Even a correct factor cannot prove title, boundaries, possession, mutation, encumbrances or the accuracy of the underlying record. Those questions belong to the official process and appropriate professionals. Keep the factor status visible in any shared calculation.
Bigha conversion record
When keeping or sharing a conversion, write the quantity, spelling used on the record, state, district or locality, square-foot factor, status, source, exception and date checked. Preserve the original regional-unit entry beside the standard-area result. This record is more useful than a bare number because another person can see whether the factor matches the same place and can repeat the calculation without assuming every Bigha is identical.
- Never average state or district factors.
- Prefer the exact deed and current official record.
- Keep customary and approximate warnings attached.
