Search "Bigha to acres" and you'll find dozens of calculators giving a single confident number — and most of them are wrong for at least part of India. Traditional land units like Bigha, Katha, and Biswa genuinely vary by state, and sometimes by district or local tradition within a state. Unit & Area Converter handles this properly, by region, rather than pretending one number fits everywhere.
Why a single "1 Bigha = X acres" answer is misleading
A Rajasthan Pucca Bigha, a Punjab Bigha, and a Uttar Pradesh Bigha are not the same real area — treating them as interchangeable produces a genuinely wrong answer, not just an imprecise one. The regions currently covered, each with its own accurate figures:
- Rajasthan (Pucca/Standard)
- Punjab / Haryana (Pucca)
- Uttar Pradesh (Western)
- Uttar Pradesh (Eastern)
- Bihar
- West Bengal / Assam
- Madhya Pradesh
- Tamil Nadu / South India
The steps
-
Select your state/region
Pick from the list above — each region has its own explicitly labeled unit set, not a generic shared conversion.
-
Choose your unit and enter a value
Bigha, Katha, Biswa, or whichever units apply in your selected region.
-
Convert to acres, hectares, or square meters
Or convert between two regional units directly if you need that instead.
Universal units too
The same tool also converts standard area units (square meters, hectares, acres, square feet, square kilometers) and standard length units (meters, kilometers, feet, miles) — useful on its own, without needing a regional context.
