What is Dhur To Biswa Bihar Up Converter?
Convert Dhur to Biswa. 20 Dhur = 1 Katha (Bihar); approximate comparison with UP Biswa.
Historical origin and significance of the Dhur
The Biswa derives from the Sanskrit vinsha meaning twentieth -- it is always 1/20 of the local Bigha. British colonial land settlement reports from the 1860s record the Biswa as the unit patwaris used for calculating individual field sizes in khasra-khatauni registers. The UP Revenue Code legally codifies 1 Biswa at 1,350 sq ft. Its sub-unit Biswansi was used to record fractional ownership in joint-family landholdings.

Conversion accuracy and official sources
The conversion factor used — 1 Dhur = 0.050000 Biswa — is sourced from: State Revenue Department records, DILRMP (Digital India Land Records Modernisation Programme), and official Jamabandi portal documentation.
Traditional Indian measurement units can vary between districts within the same state, between historical periods, and between formal (government-recorded) and informal (market-practice) usage. The factor used here represents the current officially notified standard.
This calculator applies the Bihar/UP official standard. Conversion factors for traditional Indian units vary between states and sometimes between districts. Always verify the applicable local standard with your district patwari, sub-registrar, or BIS-certified assayer before finalising any legal or financial transaction.
Step-by-step verification guide
- Obtain official documents first. For land: retrieve Khasra-Khatauni from your state land records portal. For gold: request a BIS hallmark certificate. The area or weight will be stated in the traditional unit alongside the metric equivalent.
- Use calibrated instruments. For land: a licensed surveyor uses a standard Gunter chain (66 feet) or electronic total station. For gold and cooking: use a BIS-certified laboratory balance traceable to the National Physical Laboratory (NPL India).
- Verify boundary markers. Every registered plot has boundary pillars (dhaiya) at corners. Measure each boundary independently and verify against the document dimensions.
- Cross-check with the issuing authority. For any transaction above Rs 10 lakh, an official survey by the revenue department or a BIS-certified assayer is recommended before registration.
- Convert to metric for official submissions. All government filings (RERA, bank valuations, mutation) require metric units. Use the conversion this calculator provides for your official submission documents.
Common errors and how to avoid them
- Assuming a uniform standard across states. The Dhur varies significantly by state. Always confirm the state-specific standard before converting.
- Confusing similar-sounding units. Many Indian measurement units share similar names but differ widely in value. For example, Bihar Dhur (68 sq ft) and Tripura Dhur (3.6 sq ft) are entirely different despite the same name.
- Using outdated factors. Some older websites cite historical or regional variants. This calculator uses the current officially notified standard.
- Premature rounding. For property transactions, use full decimal precision. A rounding error of 0.1 Dhur on a 10-unit plot can represent a legally significant area.
- Not accounting for deductions. In land measurement, recorded area includes rights-of-way, water channels, and boundary widths. Usable (net) area is typically 95-98% of gross recorded area.
